Happy 100th Birthday to the Turbocharger

A century ago, Swiss engineer Alfred Buchi was studying steam turbines when inspiration struck: Why not spin the wheel with exhaust from an internal combustion engine and use the recovered energy to force-feed the intake side? It was a brilliant concept, since roughly a third of the energy in fuel is normally squandered out the tailpipe. Buchi applied for a patent to cover his invention in 1905.

ADS News – The Passenger Car & Light Duty Vehicle (LDV) Diesel Engine Market 2013-2023

NEW YORK, Oct. 22, 2012 — /PRNewswire/ — Reportlinker.com announces that a new market research report is available in its catalogue: The Passenger Car & Light Duty Vehicle (LDV) Diesel Engine Market 2013-2023 Diesel engines are becoming an increasingly attractive solution to high oil prices and the resulting high running costs of passenger cars and LDVs. Diesel engines are 20-40% more efficient than petrol engines depending on vehicle size and performance. Higher efficiency results in lower fuel consumption and lower carbon dioxide emissions for comparable performance. Diesel engines thus offer a solution to both economic and environmental challenges in the automotive sector. As a consequence Visiongain has determined that the total number of unit sales in the passenger car & LDV diesel engine market in 2013 will reach 11.54m.

ADS News – Ford Fiesta Gets 90 mpg with ECOnetic Diesel Engine

Just when you thought the internal combustion engine was dead, Ford engineers produce a 1.6-liter diesel engine that blows away the fuel-efficiency marathon record with an astounding 90.65 mpg in a Ford Fiesta. The record was set at the respected Fleet World MPG Marathon event that was recently held in the UK. The Fiesta with ECOnetic Technology used just 16.22 liters (4.28 gallons) over the 624 km (388 mile) course. The marathon takes the competitors and their cars over public roads “through tricky conditions” in south Wales and the Cotswold region of England.

The record result was set during the 2012 ALD Automotive/Shell FuelSave MPG Marathon, and was organized by Fleet World magazine in the UK. The diesel powered Ford Fiesta went up against competition including the Toyota Yaris Hybrid, Fiat Panda Multijet Easy, Volkswagen Golf Match Tdi 105 and Kia Rio 1.1 CRDi 1 Eco.

The driver used Eco-driving techniques, and the results were 21 percent lower than the official fuel-mileage ratings. But the results still come from real-world driving conditions on public roads. “Eco-driving techniques can massively lower your fuel consumption in any car, but to reach such levels you need a car designed for the job, and Fiesta ECOnetic Technology certainly is,” said Andreas Ostendorf, vice president Sustainability, Environment and Safety Engineering, Ford of Europe.

ECOnetic Technology brings together a range of new fuel-saving technologies. It starts with Fords new fuel-stingy 1.6-liter TDCi diesel engine. Diesel engines have always been known to be fuel-efficient and Ford’s new engine technology is proving they are here to stay. European automakers has been using diesel powerplants for decades and have been hugely successful in powering their cars.

Other ECOnetic Technology features on the marathon-winning Ford Focus include Auto-Start-Stop, Smart Regenerative Charging, Active Grille Shutter, EcoMode, Gear Shift Indicator, bespoke engine calibration and optimized gear ratios with a six-speed transmission. The Fiesta also gets a lower suspension, wheel deflectors and low-rolling resistance tires that reduce friction from the air and road. The Ford Fiesta also incorporates special underbody shielding making it highly aerodynamic.

While most drivers won’t achieve the kind of mileage the marathon vehicle produced, the Ford Focus with ECOnetic Technology still gets impressive fuel economy of over 70 mpg. The Ford ECOnetic Technology will also be put in the new Ford Focus which will go on sale across Europe this month. The 2012 Ford Fiesta is already Europe’s number one selling small car, and when Ford of Europe’s most fuel-efficient passenger car hits showrooms, it may move the small diesel powered car to the top of the list. Let’s hope Ford brings the fuel-stingy diesel to the U.S.

ADS News – LiquidPiston Unveils Ultra Efficient, Small Diesel Engine

By Katie Fehrenbacher from Gigaom

The internal combustion is officially still alive, and delivering efficiency innovation.

While electric cars get a lot of media attention, the reality is that the internal combustion engine is far from dead, particularly for the future car owners in the developing world. A startup called LiquidPiston — which has been around for years and which got its start as a father-son team in a business plan competition at MIT — is in the process of developing a diesel engine which is far more efficient, smaller and quieter than a standard diesel engine.

The engine, called the X2, will be available as a beta prototype for outside testing by the first quarter of 2013. The engine is able to achieve more than 50 percent efficiency under typical operating modes, while typical diesel engines usually achieve less than 20 percent efficiency.

The X2 is a new type of engine architecture, based on a rotary engine. LiquidPiston CEO and President Alexander Shklonik told met in an interview that this new version of the rotary engine is more flexible and can thus be more efficient when optimized in the right way. The engine is smaller, lighter, and cheaper, with ten times fewer parts, than current diesel engines on the market, says Shklonik.

Shklonik told me in a phone interview that the first applications for the engine won’t be the mainstream automotive industry, but will be industries like defense, long haul trucks, plug-in vehicle range extenders, and other more niche markets. LiquidPiston has raised $12.3 million so far, and tells me that it’s looking to raise another $20 million later this year. The company has around 12 employees.

Other startups that have developed more fuel efficient engines include EcoMotors, Pinnacle Engines, and IRIS Engines. More efficient engines will be used in both the next-generation of cars sold in developing countries, and also countries like the U.S. that have new fuel efficiency standards. The Obama administration passed the CAFE standards, which require a fuel efficiency of 54.5 miles per gallon by 2025.

BorgWarner’s award-winning regulated two-stage (R2S®) turbo-charging technology boosts performance while helping improve fuel efficiency and lower emissions for the first four-cylinder engine in the history of the Mercedes S-Class. The 2.2-liter diesel S 250 CDI Blue EFFICIENCY is the first car in the luxury segment to consume less than 6 liters of fuel per 100 km.

Everybody wants more for less these days, and that premise is the key to the success of Drive’s Car of Year for 2011, the Mercedes-Benz C250 CDI.

The family-sized Benz has more torque, or pulling power, than a lot of petrol-guzzling V8s, yet it uses less fuel than the average city runabout.

The secret to this impressive balancing act is the diesel engine that lurks beneath its stately bonnet. 

So what makes diesel cars, and our Car of the Year, the Mercedes-Benz C250 CDI, a winning formula?

Well, for a start the C250CDI can accelerate from 0 to 100km/h in just a tick over seven seconds, which is similar performance to a big six-cylinder petrol engine. Take it out on the freeway and its rolling acceleration will be the equal of many V8s, which makes long-distance cruising and overtaking an effortless exercise.

That is impressive in itself, but when you add the fact that it uses a claimed average of 5.1 litres per 100km – less than the tiny Volkswagen Polo – it is outstanding. The figures help explain why 20 of the 46 vehicles in this year’s awards are diesel powered.

Fuel economy and reduced CO2 emissions have become a top priority for every car maker and modern common-rail diesel engines, matched to the latest fuel-saving techno-trickery, are one of the easiest paths to greener motoring.

The Mercedes, and nine other finalists, use stop-start technology to improve fuel consumption in congested cities. When the car is stopped at the lights, the engine switches off to save fuel.
