The Mercedes-Benz diesel V8
STUTTGART, Germany - Mercedes-Benz has developed a new V8 diesel
engine for its E420 CDI sedan.
The new engine incorporates common-rail direct injection, piezo
injectors, twin turbocharging with variable turbine geometry,
electrically controlled exhaust gas recirculation and a water-cooled
The engine is made using sand-cast aluminum. In order to minimize noise
and vibration, the engine is mounted on a bedplate and incorporates a
balancer shaft, which rotates in the opposite direction of the
crankshaft. The cylinders are set at a 75-degree angle.
With a performance of 314 horsepower at 3,600 rpm and 538 pound-feet of
torque at 2,200 rpm, the new 4.0-liter engine generates 20-percent more
power and 30-percent more torque than Mercedes' previous 8-cylinder CDI
power plant. The car accelerates from zero to 60 mph in 6 seconds, and
claims a top speed of 150 mph.
The new engine will debut in the E-Class in fall 2005, and it is
expected to be introduced in other Mercedes-Benz models later.
What this means to you: Those stats could be the beginning of a
beautiful relationship. Now if only they were available to North
America as crate engines...the possibilities boggle the mind.
