2021 Proton Persona facelift !!!!

 

Proton The 1.5 TGDI unit, codename JLH-3G15TD, is co-developed by Geely and Volvo,Proton

 ☺

We’ve just received confirmation from Proton’s officials that the 2020 Proton X50 1.5T & 1.5 TGDi will both be 3-cylinders. Our earlier reports that indicates the 1.5-litre multi-port injection turbo engine is a 4-cylinder unit is incorrect. All articles have since been amended.

Proton will be offering two 1.5-litre turbocharged 3-cylinder engine options for the X50 the difference between them is the type of fuel system used. The lower output 1.5T unit uses a multi-port injection (MPI) while the 1.5 TGDI uses direct injection.

 

The 1.5 TGDI is only available in the range-topping X50 Flagship variant. While the 1.5T will be featured in the other variants.

Both engine options are paired to the same 7-speed wet dual-clutch transmission first seen in the Proton X70 CKD. However, the 7DCT in the X50 will have a different calibration from the X70.

The 1.5 TGDI unit, codename JLH-3G15TD, is co-developed by Geely and Volvo. It develops 177 PS and 255 Nm of torque, making the X50 the most powerful car in its class.

However, there is very little info about the 1.5T as it is a new engine that will be making its debut in the X50. All we know that it will have 3-cylinders, a turbo, MPI, 7DCT, and makes 150 PS – the output figures we assure you, is accurate and verified by Proton.

Once again, we apologise for the misinformation.

Doble Water Tube Boiler (monotube)Doble Steam Motors automobiles

 ♥

Doble Water Tube Boiler (monotube)Doble Steam Motors automobiles, built from 1924-1931, are considered by many to be the finest steam vehicles ever produced, with the boiler figuring significantly in this evaluation.  An electric fan and igniter made the burner faster and easier to start and the small volume of fluid in the water tube boiler reached operating temperature and pressure in much less time than the Stanley.           Doble imagesThe Doble is a once-through boiler, water entering one end and heat applied until emerging from the other as steam in contrast to recirculating boilers which cycle water endlessly through a heating loop, extracting only that portion converted to steam.   The Doble is also a monotube boiler, meaning there is only one tube for the water to pass through rather than a number of parallel tubes.*The small water volume provides little reserve power in excess of maximum steady state output.*Superheating in a tube only starts above the water level; minor level fluctuation changes the length of the portions generating and superheating steam, making accurate control difficult.*The peak firing rate is limited by DNB and a circulation ratio of 1. Notwithstanding the above tradeoffs, monotube boilers have been the favored steam car boiler for generations and only relatively recently are we seeing a shift.The Doble monotube is composed of a number of helical ‘pancake’ coils, so named because the tube windings comprise flat discs stacked upon one another and connected end-to-end.  Water entering a ‘pancake’ from the outside spirals inwards until reaching center, moves upwards to the next ‘pancake’ and then spirals outwards.  See image o

Aston Martin Valkyrie’s 6.5-liter V-12

While the Valkyrie V-12 doesn’t have boost, it does have two other important factors in making power: high-revving capability, and large displacement. That combination allows more air to be fed into the engine, allowing for more power. It’s the reverse of the downsized turbocharged engines used in other cars, including Aston’s own Vantage and DB11. Those engines try to make up for smaller displacement by forcing more air in under pressure with turbos.

The engine’s high redline necessitated gear-driven camshafts, instead of a conventional timing belt or chain. The gears are located at the rear of the engine to reduce noise. The V-12 also uses port injection, rather than direct injection, because the latter would have required a particulate filter to meet European emissions standards. The engine does have four catalytic converters—two for each bank of cylinders.

Watch the full video for more details on this remarkable engine. Fenske also briefly discusses the engine for the upcoming Gordon Murray T50 supercar, which was also developed by Cosworth. Like the Valkyrie engine, the T50 engine is a high-revving (up to 12,100 rpm) naturally-aspirated V-12. However, it’s a bit smaller (3.9 liters) and develops less power (650 hp).

Fiat to build two cylinder SGE engine in Poland,The technology combines the latest 3-cylinder FireFly 1-litre

Hybrid Technology In 2020 Fiat 500 And Panda Begins Electrification Of Italian Brand

Some manufacturers believe that when a car has a small engine, say below 1.2 litres, fuel efficiency is already very good and there is no need for the added cost of a hybrid powertrain, not to mention extra weight. However, if fuel consumption can be improved further by adding an electric motor, why not?

This is how engineers at Fiat Chrysler Automobiles (FCA) see it and part of the reason why they developed FCA’s first city cars with new petrol Mild Hybrid technology. The technology combines the latest 3-cylinder FireFly 1-litre 70 bhp/92 Nm engine family with a 12-volt BSG (Belt-integrated Starter Generator) electric motor and a lithium battery pack.

Compared to the 1.2-litre 69 bhp Fire, the 77-kg Mild Hybrid version improves fuel efficiency, thus reducing carbon dioxide emissions by 30% on average, without sacrificing performance. The BSG system, allows for quiet, vibration-free restarting of the petrol engine in Stop&Start mode.

The BSG system is mounted directly on the engine and is operated by the belt that also drives the auxiliaries. The system recovers energy during braking and deceleration, stores it in the battery pack which has a capacity of 11 Ah. It can then use this energy, at a peak power of 3.6 kW, to restart the engine in Stop&Start mode and to assist it during acceleration.

Customers also benefit from all the advantages of going hybrid (the car is Euro 6D Final-compliant, for instance), which, depending on local regulations, include freedom of access and movement in European city centres, cheaper parking in town centres and tax breaks.

The first models to get the Mild Hybrid technology are the Fiat 500 and Fiat Panda, the two ‘souls’ of the Fiat brand for decades. The first, the more emotional one, is the pop, fashion and design icon. The second, the more functional, trendy one, with 5 doors. Sales will commence from February and March 2020, respectively.

Launch Editions for the first time
Furthermore, for the first time in the history of the two iconic and complementary Fiat brand models, the 500 and the Panda will be available in a special unique series: the exclusive ‘Launch Edition’. The special series can be recognized by the ‘Hybrid’ badge on the rear and the exclusive ‘H’ logo, formed by two dew drops, on the centre panel.

Dew – the symbol of the light of dawn and therefore of the beginning of a new era – has been used as inspiration for the new and exclusive ‘Dewdrop Green’ exterior finish that fits both cars like a bespoke suit, in perfect harmony with the themes of nature and innovation.

Pursuing a sustainable philosophy
On the inside, the seat upholstery is faithful to the sustainable philosophy of the entire project. The Launch Edition seats are the first in the automotive sector to be partly made with SEAQUAL YARN, the weaving of which produces a special material derived from recycled plastic. SEAQUAL YARN is produced by transforming plastics collected from the sea into flakes of polyethylene terephthalate. These flakes are then used in the yarn from which the fabrics are made.

Fiat is collaborating with SEAQUAL INITIATIVE to support ocean clean-ups to act against marine litter. The two Launch Edition models will therefore satisfy the customer who is just as attentive to aesthetics as to environmental issues, in terms of consumption and emissions.

Electrification of the brand
2020 also marks the new milestone in the history of the Fiat brand. With the launch of the new hybrid versions of the 500 and Panda, the electrification of the brand will begin, and will continue with the start of production in Turin of the new 500. This model will be 100% electric and therefore play a key role in the e-Mobility by FCA strategy.

Fiat to build two cylinder SGE engine in Poland

Fiat has decided that it will be building its new small SGE engine at its Bielsko Biala plant in southwest Poland. The SGE (Small Gasoline Engine) is Fiat’s smallest engine with only two cylinders and a 900cc displacement. It will be going into the upcoming Fiat Topolino and other small Fiat cars like the Fiat 500, Fiat Panda and possibly the Fiat Grande Punto as an economical baseline engine.

The engine will be equipped with Fiat’s Multiair electronic variable valve timing system and will have a few tune levels available ranging from a normally aspirated 65hp output to a turbocharged 110hp output. The engine design reduces the weight of a conventional 4-cylinder by 20% and installed volume by 25%.

how is Koenigsegg going to top this level of engineering geekery?

Getting 150-200bhp from a 3-cylinder engine is fairly normal these days, but how about triple that figure?! Koenigsegg recently released the Gemera – the first ever four-seater hypercar – and while it develops 1,700bhp in total, the most remarkable thing is that 600bhp of that comes from a 3-cylinder engine. As always, Christian von Koenigsegg has been as innovative as ever.

The  is awash with mind-blowing details. The most fascinating element is surely the engine - despite having only three cylinders and displacing just 2.0 litres, it produces 600bhp.

It’s also mounted in the middle yet powers the front wheels and has a seven-clutch gearbox, but less focus on one thing at a time - in this case, the output. How, exactly, has Christian and his team pushed so much out of such a small and light (70kg) package? Thankfully, YouTube’s most prominent whiteboard enthusiast Engineering Explained is here to make sense of what’s going on inside the Tiny Friendly Giant’s diminutive frame.

We’d recommend watching the whole thing and absorbing all of the knowledge Jason Fenske lays down, but what we will say is there are a few main areas that help the TFG achieve a specific output two and a half times greater than the next highest three-pot.

The TFG has huge bores and a very long stroke, but despite that, it’s capable of revving to 8500rpm. In other words, you have big pistons moving very far and very quickly. It also has a very clever sequential turbocharger setup and a ‘FreeValve’ cylinder head that controls the valves via pneumatic actuators, negating the need for a conventional camshaft.

Makes you wonder - how is  going to top this level of engineering geekery?

DARPA Making Progress on Miniaturized Atomic Clocks for Future PNT Applications

Researchers on the ACES program show early signs of success in developing chip-scale atomic clocks with 1000x performance improvements

OUTREACH@DARPA.MIL

8/20/2019

Many of today’s communications, navigation, financial transaction, distributed cloud, and defense applications rely on the precision timing of atomic clocks – or clocks that track time based on the oscillation of atoms with the highest degrees of accuracy. Harnessing the power of atoms for precise timing requires a host of sophisticated and bulky technologies that are costly to develop and consume large amounts of energy. New applications and technologies like 5G networks and GPS alternatives will require precise timekeeping on portable platforms, driving a demand for miniaturized atomic clocks with a high degree of performance.

Over the past few decades, DARPA has invested heavily in the advancement and miniaturization of atomic clock technology, generating chip-scale atomic clocks (CSACs) that are now commercially available and offer unprecedented timing stability for their size, weight, and power (SWaP). However, the performance of these first-generation CSACs are fundamentally limited due to the physics associated with their designs. Calibration requirements and frequency drift can generate timing errors, making it difficult to achieve the highest degrees of accuracy and reliability in a portable package. DARPA’s Atomic Clock with Enhanced Stability (ACES) program is exploring the development of next-generation, battery-powered CSACs with 1000x improvement in key performance parameters over existing options.

“Shrinking atomic clocks from large cesium beam tubes to chip-scale devices without eroding performance requires a rethinking of a number of critical components, including vacuum pumps and optical isolators as well as new approaches to component integration,” said Dr. John Burke, the program manager leading ACES in DARPA’s Microsystems Technology Office (MTO). “The target metrics we outlined for the ACES program are lofty, but as we enter the third phase of the program, researchers are already demonstrating engineering successes including reduced SWaP, lab-proven atomic clock technologies, as well as early prototypes of future clock architectures.”

Through the exploration of alternative physics architectures and novel component technologies, three sets of researchers have demonstrated early progress towards creating CSACs with 1000x improvement in temperature control, aging, and retrace.

A paper recently published in Optica highlights recent progress made by a team of researchers from the National Institute of Standards and Technology (NIST), with support from researchers at the California Institute of Technology, Stanford University, and Charles Stark Draper Laboratories. The team has demonstrated an experimental optical atomic clock that is comprised of only three small chips and supporting electronics and optics. Unlike standard atom clocks that operate at microwave frequencies and track the vibrations of cesium atoms, optical atomic clocks run at higher frequencies, offering greater precision because they divide time into smaller units. The NIST team’s clock uses a laser to track the oscillations of rubidium atoms confined in a vapor cell – or tiny glass container – that is 3 millimeters across sitting on top of a silicon chip. Within the clock’s chip-based “heart,” two frequency combs act like gears to convert the rubidium atoms’ high-frequency optical “ticks” to the lower microwave frequency, which is used by most PNT applications to track time. In addition to providing a higher-degree of accuracy (roughly 50 times better than the current cesium-based CSACs), the experimental clock uses very little power – just 275 milliwatts.

In addition to successfully demonstrating a chip-scale optical clock, the NIST team was able to microfabricate all of the key components, much in the same way that computer chips are fabricated. This enables further integration of the electronics and optics while creating a potential path towards mass production and commercialization.

A second team of researchers from Honeywell, working in partnership with University of California, Santa Barbara, is developing precision atomic sensors to support the development of a miniature atomic clock.

To date, the miniaturization of trapped-atom sensors has been stymied by bulk optical elements - such as lenses and mirrors - that traditionally compose the necessary optical system. The precision atomic sensors the Honeywell team has developed rely on a magneto-optic trap (MOT), which requires a three-dimensional arrangement of laser beams coming from different directions, precisely crossing at a point. To achieve this precise configuration without the use of lenses or mirrors, the researchers developed an integrated photonic chip that guides light around an “optical circuit” – which is analogous to the guiding of electrical signals in traditional computer chips. The photonic chip emits three large collimated beams of light in the proper three-dimensional arrangement to make a MOT. By combining these intersecting laser beams with a specialized set of compact magnetic field coils, Honeywell used this light source to trap rubidium atoms, and realize an advanced, miniature atomic clock.

Honeywell’s integrated photonic chip technology not only reduces the size, weight, and power of laser delivery systems, but also allows for batch fabrication of complex optical systems with reduced manufacturing cost.

Finally, a team from NASA’s Jet Propulsion Laboratory (JPL), with support from researchers at SRI International; University of California, Davis; and University of Illinois Urbana-Champaign, has demonstrated an experimental atomic clock capable of meeting ACES’ target metrics, while proving immune to temperature and environmental issues. Building off research that created the Deep Space Atomic Clock (DSAC), the team developed an ion-based approach to atom cooling that relies on ionized mercury and ultraviolet lamps instead of lasers. The JPL atomic clock showed an immunity of less than 1 part in 14 decimal places for 1 degree Celsius change. To put that in perspective, that is about 100x better than current CSACs. The use of mercury ions also provides more stability while making the technology less sensitive to magnetic fields and temperature changes.

As evidenced by the NIST and Honeywell research, progress on the ACES program is generating new means of fabricating atomic clock technologies at wafer scale, which makes continued exploration more cost effective and less reliant on massive engineering endeavors. “Today, we are dealing with complicated optical systems that require massive amounts of engineering whenever you want to iterate on a design. The early progress made on ACES shows that there are viable options in development for doing this same thing without the massive engineering manpower or hefty costs associated with current approaches,” noted Burke.

TVS Motors has patented a new type of transmission for motorcycles. Christened SMT (semi-automated manual transmission), this gearbox is an evolution of the clutchless gearbox that the company had first used in the TVS Jive, back in 2010.

This new gearbox will employ buttons on the switchgear to allow the rider to change gears. Whenever these buttons are triggered, an electric motor will take care of changing the gear according to the rider’s preference. TVS says that this SMT gearbox can also be used for three-wheelers. Since the principle behind the operation of the gearbox is the same, there won’t be a drop in fuel efficiency. Honda uses a similar mechanism for its litre-class range including the VFR1200 and the Africa Twin, though the gearbox in question is a completely automatic transmission unlike the one patented by TVS.

While the Jive’s transmission was quite revolutionary, this mechanism had a few issues. The effort required to engage a gear was larger than on a conventional gearbox. Besides, even a slight pressure on the gear lever activated the clutch, leading to unexpected behaviour of the powertrain and an increase in fuel consumption. With this new SMT gearbox, TVS will aim to retain the convenience while getting rid of the niggles.

recent years AMT gearbox has gained immense popularity, and its use in entry level cars is more prevalent than ever before. It offers an unbeatable combination of affordability and convenience. Not only that, the fuel efficiency that it has to offer is in fact more than what you would get with a manual gearboxes. They are also not expensive to maintain as some of the other automatic gearbox technologies. So, how does it work? The article answers some basic questions related to the AMT transmission.

What is an AMT transmission?

At the heart of the AMT transmission is a manual gearbox, hence the name – Automated Manual transmission. It is a two pedal technology just like all other automatic transmissions, and uses actuators for clutch and gearshift operations. Actuators are either electro-mechanical or electro-hydraulic type.

Note that there is a clutch, but no clutch pedal, so in the background the clutch and shifts are operated by actuators. All this is precisely controlled by the TCU (Transmission Control Unit).

Which cars offer the AMT transmission?

Maruti Alto K10, Tata Nano, Maruti Swift Dzire, Renault Duster, Tata Zest, Mahindra TUV300 are a few other cars that offer AMT transmission.

What are the modes of operation available in an AMT gearbox?

Most AMT gearboxes offer two modes of operation – Semi automatic & fully automatic. In case of fully automatic mode, the car drives like an automatic car and gear change takes place in accordance with your input at the accelerator / brake pedal. While the semi automatic mode has a provision for driver input and he can change the gears by pushing the gear lever forward or back. However, unlike a manual, there’s no need of clutch.

Are there any other differences between AMT and traditional automatic gearbox?

A traditional automatic offers ‘Creep’ function which enables the car to move forward as soon you take your foot off the brake pedal. Until recently the AMTs offered by different car companies did not offer the ‘Creep’ function and therefore, you required to use the accelerator pedal after releasing the brake pedal.

The new AMT systems developed by companies like Ricardo for TUV300 offer the creep function. Another car that offers the creep function includes Tata Nano. Cars from Maruti like Celerio and Alto K10 does not offer this feature. The Tata Zest is another car that skips the Creep functionality.  

Which are the different companies that develop the AMT gearbox?

Among the prominent companies like Magneti Marelli & Ricardo some other names among manufacturers include Getrag, ZF and Wabco.
