1. V-type automobile cylinder heads: The cylinders of the automobile are arranged in two rows, and the angle between the centerlines of the left and right cylinders γ <180 ° is called a V-type engine. Compared with an in-line engine, a V-type vehicle The cylinder head greatly shortens the length and height of the body and increases the rigidity of the cylinder block, thereby achieving the purpose and effect of reducing the weight of the engine. However, the width of the engine is increased, and the shape is more complicated, and the processing is difficult. It is generally used for 8 cylinders Above the engine.
Second, the in-line automobile cylinder head: the cylinders of the automobile engine are arranged in a row, generally arranged vertically. The single-row cylinder block has a simple structure and easy processing, but the engine length and height are relatively large. According to the existing situation on the market, engines with less than six cylinders are mostly single-row. For example, the engines used by Jetta cars, Fukang cars, and Hongqi cars use this type of inline car cylinder head.
3. Opposed car cylinder heads: The cylinders of this type of car cylinder heads are arranged in two rows, at least to ensure that the left and right cylinders are on the same horizontal plane, that is, the angle between the centerlines of the left and right cylinders is 180 °, which is called Opposition. The opposite type of automobile cylinder head is characterized by its small height, and its overall arrangement is very convenient, which is conducive to air cooling, but in general, there are fewer such cylinders on the market.
