The composition and function of the body group?

1. Composition: cylinder head, cylinder block and crankcase Function: As the assembly base of the engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and forms the frame of the tractor with the relevant parts of the tractor chassis.

2. The body group is the bracket of the engine, which is the assembly substrate of the crank connecting rod mechanism, the gas distribution mechanism and the main parts of the engine system. It is composed of a cylinder head cover, a cylinder head, a cylinder pad, a cylinder block and an oil san shell. The cylinder head is used to close the top of the cylinder and form a combustion chamber with the piston top and the cylinder wall.

3. The function of the fuselage group is to form the skeleton of the engine, support all the moving parts, install the auxiliary system, and use the crankcase to hoist the engine assembly on the frame.The fuselage group includes crankcase, cylinder, cylinder head, etc., as shown in Figure 1-4. Figure 1-4 The engine body group consists of 1 crankcase.

4. The functions and composition of the fusele group are as follows: the engine body is the support of the engine, and its function is to provide the assembly foundation of the crank connecting rod mechanism, the gas distribution mechanism and the main parts of each system. The commonly used structure is composed of the body, cylinder head, cylinder head cover, cylinder pad, main bearing cover and oil span shell.

5. The fusele group is mainly composed of cylinder head, cylinder head, cylinder gasket, cylinder block, main bearing cover and oil pan shell, etc. Engines with cylinder liners are also divided into dry or wet cylinder liners. The cylinder head is used to close the top of the cylinder and form a combustion chamber with the top of the piston and the wall of the cylinder.

What structures does the car engine consist of?

1. 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.

2. Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of the engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis form the frame of the tractor.

3. The engine is composed of two major mechanisms and five major systems. Two major mechanisms: crank connecting rod mechanism. 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.

4. The body is the skeleton that constitutes the engine and the installation basis of the various mechanisms and systems of the engine. All the main parts and accessories of the engine are installed inside and outside, bearing various loads. Therefore, the body must have sufficient strength and rigidity. The body group is mainly composed of cylinder block, crankcase, cylinder head, cylinder pad and other parts.

What is the function of the body group of the engine? What are the main components?

Group function: The engine body is the support of the engine, and its function is to provide the assembly basis for the crank connecting rod mechanism, the gas distribution mechanism and the main parts of each system. The commonly used structure is composed of the body, cylinder head, cylinder head cover, cylinder pad, main bearing cover and oil span shell.

Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of various engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis form the frame of the tractor.

[Pacific Automobile Network] The functions of the fuselal assembly in the engine are: to accommodate the piston; to provide space for the piston compressed air (mixer); to transfer heat to the piston; to provide guidance to the piston.

The engine body is the support of the engine and the assembly basis of the crank connecting rod mechanism, gas distribution mechanism and the main parts of the engine system. The cylinder head is used to close the top of the cylinder and form a combustion chamber together with the top of the piston and the cylinder wall.

The composition of the engine?

1. The engine is mainly composed of fuselage group, crank connecting rod mechanism, gas distribution mechanism, fuel supply system, ignition system, cooling system, lubrication system, start system, etc., as shown in Figure 1-3.

2. The body is the skeleton of the engine and the installation basis of the engine mechanisms and systems. All the main parts and accessories of the engine are installed inside and outside, bearing various loads. Therefore, the body must have sufficient strength and rigidity. The body group is mainly composed of cylinder block, cylinder liner, cylinder head, cylinder pad and other parts.

3. Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of various engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis constitute the frame of the tractor.
