Engine selection skills
According to the different arrangement of engine cylinders, there are three types of engines: in-line, horizontally opposed and V-shaped. The in-line arrangement of cylinders has the advantages of simple structure, narrow width and convenient arrangement. However, when the number of engine cylinders is too large, the length and size are too long, so it is difficult to arrange in the car, so the in-line type is suitable for engines with less than 6 cylinders. In addition, the disadvantages of in-line type are high height and large volume.
Compared with in-line engine, V-type engine has the advantages of shorter length, higher crankshaft stiffness, smaller height and more engine series. Its main disadvantage is that it is difficult to arrange when it is used in flat car because of its wide engine and high cost. ?
The main advantages of horizontally opposed engine are good balance and low height. V-type engines are mainly used in medium, high-grade and high-grade cars and heavy trucks, and horizontally opposed engine is used in a small number of passenger cars.
According to the different cooling methods of the engine, the engine can be divided into two types: water cooling and air cooling. Most water-cooled engines used in automobiles have the advantages of uniform and reliable cooling, good heat dissipation, low noise, ability to solve the problem of heat generation inside the vehicle, and better adaptability to the heat dissipation after engine pressurization after increasing the radiator area. The main disadvantage of water-cooled engine is the complex structure of cooling system;
Inconvenient to use and maintain; The cooling performance is greatly influenced by the ambient temperature. Cooling water is easy to overheat in summer and supercool in winter. If it is stored outdoors, it will freeze the cylinder block and radiator after water freezes.
