engine structure

engine valve chamber cover, engine valve cover is the valve chamber cover for short. 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.

There are two common forms of engine cylinder arrangement: single-row and double-row: each cylinder of a single-row (in-line) engine is arranged in a row, which is generally arranged vertically. But in order to lower the height of the engine, the cylinder is sometimes arranged in an inclined or even horizontal way.

Four ChongsThe Cheng motorcycle engine is mainly composed of fuselage components, crankshaft connecting rod mechanism, gas distribution mechanism, transmission mechanism, clutch and start mechanism, fuel supply system, lubrication and cooling system and other parts. Figure 1-65 is the Lifan 125 motorcycle engine.

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.

Engine decomposition diagram and structural name

Diesel engine is a diesel-fueled engine. Diesel engines have high compression ratio and high thermal efficiency, which have better economic and emission performance than gasoline engines.Diesel engines are widely used in pickup trucks, buses/trucks and construction machinery vehicles. It is also used for some luxury cars.

Crankshaft transmission mechanism The crankshaft transmission mechanism is a functional combination that converts the pressure of the combustion chamber into kinetic energy. In this process, the reciprocating movement of the piston is transformed into the rotation of the crankshaft. In terms of efficacy, efficiency and technical practicality, the crankshaft transmission mechanism is the best choice to achieve the above purposes.

The structure diagram of the automobile engine is as follows: the engine consists 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.

Engine Structure Illustration (1) Engine Appearance Drawing EngineThe appearance diagram is shown in the figure below. The engine is usually composed of cylinder block, cylinder head, connecting rod, crankshaft, camshaft, valve, piston, piston ring and other components.

Automotive engine structure

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

2. 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.

3. Basic knowledge reserve about automobile engines. The structure of engines is diverse, and the specific structure varies from a wide range. At present, most of the engines used in automobiles are resurrected internal combustion engines. A modern car engine is a complex machine composed of many mechanisms and systems. Because the basic working principle is the same, its basic structure is similar.

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. AutomobileAt present, the piston material widely used in engines is aluminum alloy, and some diesel engines also use alloy cast iron or heat-resistant steel to make pistons. The basic structure of the piston can be divided into three parts: the top, the head and the skirt. The top of the piston. The top of the piston is an integral part of the combustion chamber, which is used to withstand gas pressure.

6. The basic structure of the engine An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stling engines, steam engines, etc.), electric motors, etc. Internal combustion engines are usually converted into chemical energy into mechanical energy.

What is the structure of the car engine?

1. At present, the piston material widely used in automobile engines is aluminum alloy, and some diesel engines also use alloy cast iron or heat-resistant steel to make pistons.The basic structure of the piston can be divided into three parts: the top, the head and the skirt. The top of the piston. The top of the piston is an integral part of the combustion chamber, which is used to withstand gas pressure.

2. The basic structure of the engine (1) crank connecting rod mechanism The crank connecting rod mechanism is composed of three parts: the fusele group, the piston connecting rod group and the crankshaft flywheel group. Its function is to transform the thermal energy generated by fuel combustion into the rotational motion of the crankshaft through the linear reciprocating motion of the piston to the flywheel. Output power.

3. The device required to complete the starting process is called the starting system of the engine.

4. The basic structure of the engine An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Sterling engines, steam engines, etc.), electric motors, etc.Internal combustion engines are usually converted into chemical energy into mechanical energy.
