Mercedes-Benz new V-type 6-cylinder 3.5L engine was successfully developed


Mercedes-Benz's new V-type 6-cylinder 3.5L engine was successfully developed. DaimlerChrysler has announced that it has successfully developed a new V-type 6-cylinder engine with a displacement of 3.5L for the Mercedes-Benz model. From the spring of 2004, it will be the first to be equipped with the new generation of small roadster "SLK". The engine is a 24-valve engine, a cylinder with four steam valves, maximum output power 200kW, maximum torque 350Nm. It is said that the maximum torque can be reached at 2500 rpm, and if it continues to increase to 5000 rpm, it can climb to the peak torque. The biggest feature of the new engine is: To control the engine height, set the tilt angle to 90°. The Cylinder Block, Cylinder Head, and Crankcase are made of aluminum alloy. The suction and exhaust sides are equipped with a hydraulic continuous variable valve timing structure. The length of the suction hole of the magnesium alloy can be switched, and the suction hole also has a “Tumble Flap” which can close the lower side of the air hole in the low-speed range and enhance the valve drop. In order to reduce the weight of the cylinder liner and reduce the friction, the cylinder liner is made of aluminum-silicon alloy. It is said that with this cylinder liner, the weight of one cylinder can be reduced by 500g. Bore and stroke (Bore / stroke) ultra bore (Overbore), was 92.9 / 86.0mm, away from the cylinder (Bore Bitch) of 106mm, a compression ratio of 10.7: 1. In addition, the engine has reached the Euro 4 emission standard.
