Post: Cylinder block arrangement

Cylinder block arrangement
(1) In-line
The cylinders of the engine are arranged in a row, usually vertically. The single-row cylinder block has a simple structure and is easy to process, but the engine is longer and taller. Generally, engines with less than six cylinders use the single-row type. For example, the engines used in Jetta, Fukang, and Hongqi cars all use this in-line cylinder block. Some cars tilt the engine at an angle to reduce the height of the engine.
(2) V-type
The cylinders are arranged in two rows, and the angle γ between the center lines of the left and right rows of cylinders is less than 180°. This is called a V-type engine. Compared with an in-line engine, a V-type engine shortens the length and height of the engine body, increases the rigidity of the cylinder body, and reduces the weight of the engine, but increases the width of the engine. It is also more complex in shape and difficult to process. It is generally used for engines with more than 8 cylinders. 6-cylinder engines also use this type of cylinder block.
(3) Opposed type
The cylinders are arranged in two rows, with the left and right rows of cylinders on the same horizontal plane, that is, the angle between the center lines of the left and right rows of cylinders is γ=180°, which is called opposed type. Its characteristics are small height, convenient overall layout, and conducive to air cooling. This type of cylinder is less used.
