What are the components of a car engine?

The automobile engine is composed of five major systems and two major mechanisms, the two major mechanisms are the crank connecting rod mechanism and the valve mechanism. The five major systems are the fuel supply system, the cooling system, the lubrication system, the ignition system, and the starting system.

The engine is not one, the engine has valve chamber covers, cylinder heads, cylinder blocks, oil pans from top to bottom, and gaskets between these parts.

Inside the engine there are connecting rods, pistons, crankshafts, valves, camshafts, balance shafts, etc.

The engine is known as the heart of the car, and the engine is responsible for powering the car.

In the car, there is another very important component, and that is the gearbox. The gearbox plays the role of variable speed and torque, the gearbox belongs to the transmission system, the gearbox can transmit the power generated by the automobile engine to the wheels, and the power output of the gearbox after changing the speed and torque can meet the needs of the car in various working conditions.

There are many types of automobile engine cylinders, such as in-line cylinders, V-cylinders, W-cylinders, horizontally opposed cylinders, etc.

Most common family cars are equipped with in-line four-cylinder engines, some high-performance cars are equipped with V-cylinder engines, and some brands use horizontally opposed cylinder engines.

The car engine has a vital position for a car, it can be called the "heart" of a car, providing power for the driving of the car, related to the power, economy and environmental protection of the car, a high-quality car is inseparable from the support of the engine, and the personal safety of the driver and passengers is also closely related to the engine. 1.

The two major mechanisms of the automobile engine are the crank connecting rod mechanism and the valve mechanism.

The six major systems are: Lubrication system. Cooling system. Starting system, ignition system. Fuel supply system. Electronic control system.

The engine parts are composed of crank connecting rod mechanism, air valve mechanism, oil pump, engine family call oil filter, pressure limiting valve and other parts.

1. The crank connecting rod mechanism is the main motion mechanism of the engine to realize energy conversion and complete the working cycle, which is composed of cylinder block, cylinder head, piston, connecting rod, crankshaft and flywheel and other parts.

2. The function of the valve mechanism is to realize the ventilation process of the engine, according to the working cycle of the engine, open and close the intake and exhaust valves regularly, so that the combustible mixture enters the cylinder, and the exhaust gas is discharged from the cylinder. The valve train usually consists of a valve train, a valve train train and a valve actuator.

3. Fuel supply system.

The function of the fuel supply system of the gasoline engine is to prepare a certain concentration and quantity of fresh combustible mixture and send it to the cylinder according to the requirements of the engine. The function of the diesel engine fuel supply system is to supply diesel and air into the cylinder respectively in a certain proportion, form a mixture in the combustion chamber and burn it, so that the engine can work continuously.

4. The function of the lubrication system is to supply a certain amount of clean lubricating oil to the friction surface of the engine moving parts. It is mainly composed of oil pumps, oil filters, pressure limiting valves and other parts.

5. Cooling systemThe function of the cooling system is to absorb and dissipate the excess heat of the heated parts of the engine to ensure that the engine works at the most suitable temperature state. It is mainly composed of water pumps, cooling jackets, radiators, fans, thermostats and other parts.

6. Ignition systemThe function of the ignition system is to generate electric sparks at the specified time and ignite the combustible mixture in the gas cylinder. It is mainly composed of ignition coils, distributors, chain cover batteries, generators and spark plugs and other parts.

7. The function of the starting system is to start the engine. The crankshaft starts to turn under the action of external force, and the process by which the engine starts to run on its own is called the starting of the engine. The starting system is mainly composed of the starter and its accessories.

1.The crank linkage mechanism is the main motion mechanism of the engine to realize energy conversion and complete the work cycle, which is composed of cylinder block, cylinder head, piston, connecting rod, crankshaft and flywheel.

2.The role of the valve train is to realize the ventilation process of the engine. According to the working cycle of the engine, the intake and exhaust valves are opened and closed regularly, so that the combustible mixture enters the cylinder and the exhaust gas is discharged from the cylinder.

The automobile engine is composed of two major mechanisms and five major systems, including crank connecting rod mechanism and valve mechanism, cooling, lubrication, ignition, fuel supply, and starting system.

1. Crank connecting rod mechanism.

The mechanism is composed of three parts: cylinder block-crankcase group, piston connecting rod group and crankshaft flywheel group.

When the engine is doing work, the air pressure generated by fuel combustion is converted into torque through a series of work of the crank connecting rod mechanism, and the inertia of the flywheel is used to complete the air intake, compression, and exhaust work.

2. Gas distribution mechanism:

The mechanism consists of two parts: the valve train and the valve transmission group.

According to the working sequence of the engine and the requirements of the working cycle of each cylinder, the valve mechanism can open or close the intake and exhaust valves in time, so that the combustible mixture or fresh air can enter the cylinder and discharge the exhaust gas.

3. Cooling system.

When the engine is working, it generates a lot of heat. The existence of the cooling system is to dissipate the heat of those heated parts in time, which not only ensures the working environment of the engine but also protects the parts from injury.

4. Lubrication system.

For some parts that do relative motion, long-term work can easily cause wear and tear of the parts. The lubrication system can deliver a certain amount of lubricating oil to the surface of the parts and reduce the friction resistance between the two parts. In addition to lubrication, the surface of the part can be cleaned and cooled.

5. Ignition system.

The function of the ignition system is to ignite the combustible mixed gas in the gas cylinder, which is mainly composed of batteries, ignition coils, spark plugs and electronic control systems.

To complete the gas combustion, the head of the spark plug needs to be extended into the combustion chamber and the electric spark between the spark plug electrodes is generated on time through the control of the electronic system.

6. Fuel supply system.

The fuel supply system, as the name suggests, is to provide fuel to the engine. According to the actual working needs of the engine, the fuel supply system mixes air and gasoline into combustible gas in a certain proportion, and transports this gas to each cylinder.

7. Starting system.

The pneumatic system is used to complete the engine starting process.

It consists of a starter and its accessories, which make the crankshaft start to rotate until the engine starts to idle automatically.
