Cylinder arrangementIn-line engine
The cylinders of the engine are arranged in a row and are generally arranged vertically. But in order to reduce the height of the engine, sometimes the cylinder is arranged to be inclined or even horizontal. The single-row cylinder block is simple in structure and easy to process, but the length and height of the engine are relatively large. Generally, engines with less than six cylinders use single-row type. For example, engines used in Jetta cars, Fukang cars, and Hongqi cars all use this in-line cylinder block.
V engine
The cylinders are arranged in two rows, and the angle between the center lines of the left and right rows of cylinders is less than 180°. It is called a V-type engine. Compared with the in-line engine, the V-type engine shortens the body length and height, increases the rigidity of the cylinder body, and reduces The weight of the engine is increased, but the width of the engine is enlarged, and the shape is more complicated, which is difficult to process. It is generally used for engines with more than 8 cylinders. 6-cylinder engines also use this type of cylinder block.
Opposed engine
The cylinders are arranged in two rows, and the angle between the center lines of the left and right rows of cylinders is γ=180°.
