Fuel Pump Failures Under Scrutiny

Volkswagen and Audi TDIs are under investigation for fuel pump failures. The NHTSA opened the investigation in February 2011 on the 2009 and 2010 Golf and Jetta models. The issues seem to center around contaminated fuel and the high pressure fuel pump not being capable of dealing with diesel that’s been contaminated by gasoline either by the customer or the fueling station.

BorgWarner EFR Turbocharger Technical Training Guide

Brock Fraser is the Chief Engineer & Team Leader of the EFR project for BorgWarner Turbo Systems. In his forward to the EFR Turbocharger Technical Training Guide, Mr. Fraser describes the project vision and the process of development. Below is an excerpt from the guide Forward by Brock Fraser

“The first thing worth explaining is the strong connection between this exciting line of aftermarket turbos and our OEM commercial vehicle products. Commercial/industrial turbo products have extreme requirements for durability, reliability, and aerodynamics performance. Turbo sizing for the performance user more resembles what’s in the commercial realm as compared to what comes from our OE passenger car developments. Also required is resistance to abusive thrust loads, vibration, and robustness for a wide range of lubrication and cooling conditions. Our OE product validation standards are very tough, and many of these same practices were employed during the development of the EFR products.

Honeywell’s 2-Cylinder Diesel Engine

A new chapter in the story of ultra-fuel efficient auto design opened in 2011 with the development of the world’s first 2-cylinder turbocharged diesel engine.

Today, the 0.8L engine, boosted by Honeywell’s smallest-ever turbo, can be seen powering vehicles through the busy streets of India’s cities and towns, typically carrying goods from warehouses to local businesses. For Honeywell, boosting such a small engine created a whole new set of design and engineering challenges.

“The issues in developing a turbo for a 2-cylinder engine not only revolve around packaging but also around specific challenges linked to compressor surge, oil leakage, high vibrations and high thrust load due to engine pulsations. These issues are far more pronounced here than in a four-cylinder engine,” says Vijayan Asvathanarayanan, Director of Application Engineering for Honeywell Turbo Technologies in India.

This meant that Honeywell engineers had to approach the turbo design from a completely new angle.

“We came up with a totally new turbocharger that included a very small turbine housing with integrated manifold, and the smallest-ever compressor wheel developed by Honeywell. The higher relative thrust loads brought about by the pulsation of a bi-cylinder engine meant creating new concept thrust pads in the Z-bearing – vital if we were to be efficient in matching the turbo to the engine requirements.”

A high-efficiency, compact bearing was developed – and the design was so successful that it is now being extended to other turbo sizes as well.

The result of this intense engineering activity is a well-performing and reliable turbo fitted in the 2-cylinder OEM production engine since 2011, which is contributing to a remarkable 25% improvement in power over a non-turbo equivalent and to significant fuel efficiency gains and lower emissions.

Critically, the proven success paves the way for the roll-out of a new generation of turbocharged 2- and 3-cylinder diesel passenger cars and light commercial vehicles, particularly in emerging regions.

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.

Diesel Service Centre – Skilled and Reliable Diesel Mechanic’s on staff

There is no doubt that diesel engines far out perform gasoline engines. When properly maintained a diesel engine will last twice as long, with double the efficiency. However, when you do run into problems, fuel consumption may have increased, power is significantly reduced and systems such as air conditioning begin to fail.
Problems with performance are not the first sign of repair needs. An excess of black, white or blue smoke, coming from your exhaust pipe, is a good early indicator that your diesel system needs servicing. Also, keep an eye out for leaking fuel, as this will affect the efficiency of your diesel system and requires immediate repair. Although these are common symptoms associated with diesel engine problems, it takes an experienced mechanic to determine the root cause.
There are many signs that will suggest your diesel engine needs servicing. However, each one can result from a number of different problems. As diesel engine technology and systems improve, it makes it more difficult for an average mechanic to determine the problem. Our mechanics are skilled in all areas of diesel diagnostics, servicing and repair. At our diesel service centre we aim to ensure that your issue is resolved, first time every time.

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.
