What is the overall structure of the car engine?

There are mainly two types of engines: gasoline engine and diesel engine. The gasoline engine is composed of crank connecting rod mechanism, gas distribution mechanism and fuel supply system, cooling system, lubrication system, ignition system and start system.

In terms of its overall function, the car engine is basically composed of two major mechanisms: crank connecting rod mechanism and gas distribution mechanism;Five major systems: start-up system, fuel supply system, ignition system, lubrication system and cooling system.

Diesel engine Gasoline engine is usually composed of two major mechanisms: crank connecting rod, gas distribution and five major systems: fuel supply, lubrication, cooling, ignition and start-up. Diesel engines are usually composed of two major mechanisms and four major systems (no ignition system).

The engine is composed of two major mechanisms: crank connecting rod mechanism and gas distribution mechanism, as well as five major systems such as cooling, lubrication, ignition, fuel supply and start-up system. The main components include cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc. The working cavity of the resurrected plug internal combustion engine is called a cylinder, and the inner surface of the cylinder is cylindrical.

What is the structure of the engine?

1. The crank connecting rod mechanism is composed of cylinder block, cylinder head, piston, connecting rod, crankshaft and flywheel, etc.

2. The gas distribution mechanism is an important part of the engine. It is composed of a valve group and a valve transmission, which controls the intake and exhaust processes of the engine. The more sufficient the engine intake and the more thorough the exhaust, the greater the output power, and vice versa, the smaller the output power. Therefore, the power and economy of the engine depend on the quality of the gas distribution mechanism.

3. Figure 1-4 The engine fusele group consists of 1 crankcase. The function of the crankcase body is to form the engine matrix together with the cylinder block and cylinder head. Many parts of the engine are installed in the crankcase, which bears a variety of forces of the engine. There are two different structural types of crankcases: integral and combined. 2 cylinders.

The basic structure of the engine?

1. Engine valve chamber cover, the engine valve chamber cover is abbreviated as valve chamber cover. It is the sealing component of the top part of the engine. The engine lubricating oil corresponding to the oil sup shell is sealed, so that the lubricating oil will not leak out when the engine is running. The function of the cylinder head is to seal the cylinder, form a combustion space with the piston, and withstand the effect of high-temperature and high-pressure gas.

2. The engine is composed of two major mechanisms and five major systems: crank connecting rod mechanism, gas distribution mechanism, fuel supply system, lubrication system, cooling system, ignition system and start system. The crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It is composed of a fusele group, a piston connecting rod group and a crankshaft flywheel group.

3. Most of the gas distribution mechanisms adopt the overhead valve gas distribution mechanism, which is generally composed of valve group, valve transmission group and valve drive group.

4. In terms of its overall function, the car engine is basically composed of two major mechanisms: crank connecting rod mechanism and gas distribution mechanism; five major systems: start-up system, fuel supply system, ignition system, lubrication system and cooling system.

5. Hello, engineIt is composed of two major mechanisms: crank connecting rod mechanism and gas distribution mechanism, as well as cooling, lubrication, ignition and fuel supply. It is composed of five major systems such as the start-up system. The main accessories are. Cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc.

6. The engine is the core component of modern vehicles. Its basic structural composition includes the following aspects: cylinder block and cylinder head. The cylinder block and cylinder head of the engine are the main part of the engine. They are usually made of cast iron or aluminum alloy.
