W-type engine

Introduction

Many people think that the Cylinder arrangement of the W-type engine must also be W-shaped in the cylinder of the V-engine, and it is also a W shape, which is only approximately approximate. W-shaped arrangement, strictly, should also be a V-type engine, at least a variant of the V-engine.

W type can make the engine more shorter than the V-type engine, the crankshaft can be short, so that the space occupied by the engine, the weight is also light, but it's The width is larger, making the engine room more full.

The maximum problem with the W-type engine is that the engine is divided into two parts as a whole, and it will inevitably cause a large vibration during operation. In response to this problem, the Volkswagen designed two reverse rotational balance axes on the W-type engine, allowing the vibration of the two parts to cancel each other.

Classification

Existing W8, W12, W16 and W18.

W8 engine

Now only Passat W8 uses W8-type engines, displacement is 4 liters, and the maximum power is 270 hp / 6000 rpm. Since the length of W8 is short, it can stand in the engine room that is not too large, leaving a larger space for the driving ride.

W12 engine

Motors with Volkswagen W12 engine with Volkswagen's flagship model Phaeton, Bentley (Bentley) new car GT and Audi flagship model A8L60 three quantitative cars. Different Volkswagen W12 concept sports cars are also mounted with W12 engines. The Volkswagen's W12 engine displacement is 6 liters, the maximum power is 420 hp / 6000 rpm.

W16 engine

Volkswagen launched Bugati EB16-4VEYRON. Concept car, assembled a W16 cylinder engine, displacement and stroke and The cylinder diameter is 86mm, 64 valve, and the maximum power is 1001 horsepower / 6000 rpm.

W18 engine

in 1998, the world car Bugatti is acquired by Volkswagen, in the Paris International Auto Show, the public launched a 18 cylinder engine. Bugati EB118. This W18 engine is developed by the public and is the engine of the number of cylinders used in the world. Its displacement is 6.3 liters, the maximum power is 555 horsepower. 18 village

cylinder is divided into three rows (rather than "four roads" as the W-type engine described above), 6 cylinders per row of 6 cylinders, like it is in the center of the V12 engine. Table straight 6 engine. At that time, the mass company referred to such an engine as a W-type engine, apparently there is a difference in the cylinder arrangement of the current W-type engine, but the author believes that its arrangement is more similar to the W letters.

Classic example: The public flagship model Phaeton previously did not have a 12-cylinder engine, and the same level of Mercedes-Benz S600 was insufficient, and the public new W12 engine completely changed this disadvantage, the mass of the public Two luxury cars: Bentley (Bentley) new car GT and Audi flagship A8L6.0 will use W12 engine.
