Mercedes-Benz Is Focusing On Diesel
Published: 5th March 2005
Mercedes-Benz Vision R 320 CDI
New V8 diesel for the SL-Class
The new drive in the Vision SL 400 CDI also belongs to Mercedes-Benz’ third generation of CDI engines. To create this system, the engineers took the familiar four-litre V8 diesel and enhanced many of its components while also adding state-of-the-art piezo injectors, new turbochargers and an optimised water/charge-air cooling system. Taken together, all of these measures allow the engine to bring forth its power and torque in an even more harmonious fashion. The SL 400 CDI accelerates from zero to 62.5 mph in 5.8 seconds. As such, this diesel sports car justifiably bears the legendary letters "SL".
Diesel driving pleasure with new V6 engine
Maximum driving pleasure is also offered by the Mercedes-Benz vehicles powered by the new standard equipment V6 CDI engine. The Mercedes engineers have further developed the engine’s common rail direct injection and are using third generation technology to realise even more advances in terms of power, fuel consumption, exhaust emissions and combustion noise. Newly developed piezo injectors work much faster and more precisely than the previous solenoid valves and ensure the fuel supply to the cylinders is very accurately measured. This means the fuel injection is even more precisely adjusted to engine speeds and loads - five fuel injections per power stroke with a peak pressure of up to 1,600 bars are possible.
Thanks to precise valve timing, the V6’s emissions of nitrogen oxides and particulates more than satisfy the stringent Euro 4 limits. Two oxidation-type catalytic converters handle the conversion of the carbon monoxide and hydrocarbons. For the further reduction of particulate emissions, Mercedes-Benz is relying on its maintenance-free particulate filter system.
The V6 diesel also features the most advanced technology in terms of the materials used, design, fuel injection and valve timing. In a world first for a diesel engine of this displacement and power class, Mercedes-Benz developed an aluminium crankcase with grey cast iron cylinder liners, which especially helps to reduce weight.
Sports Tourer concept car with exciting diesel technology
In Geneva, Mercedes-Benz is presenting two new sports tourer concept vehicles with the most advanced diesel engines and a new space concept. With their spacious interiors and exemplary comfort, the new Compact Sports Tourer of the Mercedes-Benz B-Class, which is simultaneously marking its world premiere in Geneva, and the Grand Sports Tourer Vision R offer the best conditions for a relaxed and enjoyable ride.
The show car version of the Grand Sports Tourer Vision R is powered by the new V6 diesel engine; the most powerful diesel available in the new B-Class is the B 200 CDI, which delivers 140 hp and 300 Nm of torque. Also newly developed, this turbocharged diesel with common rail direct injection gives the Compact Sports Tourer the power it needs to sprint from zero to 62.5 mph in 9.6 seconds. The B 200 CDI’s maximum speed is 124 mph. And despite this superior performance, the engine’s fuel consumption is 50.5 mpg (combined consumption).
