Can anyone tell us about the interior of the car? What is the internal structure of a sedan?

Let the upstairs be all gone, I have a picture?

The engine is the power unit of the car, which is composed of 2 major mechanisms and 5 major systems, namely the crank connecting rod mechanism, the valve mechanism, the cooling system, the fuel supply system, the lubrication system, the ignition system, and the starting system, but the diesel engine is less than the gasoline engine, and the stool is an ignition system. 2. Automobile chassis: The role of the chassis is to support and install the assembly of the automobile engine and its various parts to form the overall shape of the automobile and accept the power of the engine, so that the automobile can move and ensure normal driving.

The chassis is composed of four parts: the base of the drive train, the driving system, the steering system and the brake system. 3. Automobile body: The body is installed on the frame of the chassis for the driver, passengers to ride or load goods.

The body of the car and bus is generally an integral structure, and the body of the truck is generally composed of two parts: the cab and the cargo box. 4. Electrical equipment: electrical equipment is composed of two parts: power supply and electrical equipment.

The power supply includes a battery and a beating motor; Electrical equipment includes the starting system of the engine, the ignition system of the gasoline engine and other electrical devices.

An engine is a complex machine that consists of many mechanisms and systems. Whether it is a gasoline engine, or a diesel engine; Whether it's a four-stroke engine or a two-stroke engine; Whether it's a single-cylinder engine, or a multi-cylinder engine. In order to complete the energy conversion, realize the work cycle, and ensure the continuous normal operation for a long time, the following mechanisms and systems must be in place.

1) Crank linkage mechanism.

The crank linkage mechanism is the main moving part of the engine to realize the working cycle and complete the energy conversion. It is composed of a body group, a piston connecting rod group and a crankshaft flywheel group, etc. In the power stroke, the piston is subjected to gas pressure in a linear motion in the cylinder, which is converted into the rotary motion of the crankshaft through the connecting rod, and outputs power from the crankshaft.

During the intake, compression and exhaust strokes, the flywheel releases energy and converts the rotational motion of the crankshaft into the linear motion of the piston.

2) Gas distribution mechanism.

The function of the valve mechanism is to open and close the intake and exhaust valves at regular intervals according to the working sequence and working process of the engine, so that the combustible mixture or air enters the cylinder, and the exhaust gas is discharged from the cylinder to realize the ventilation process. Most of the valve trains adopt overhead valve valve mechanisms, which are generally composed of valve groups, valve transmission groups and valve actuation groups.

3) Fuel supply system.

The function of the fuel supply system of the gasoline engine is to prepare a certain amount and concentration of mixed gas according to the requirements of the engine, supply it to the cylinder, and discharge the exhaust gas after combustion from the cylinder to the atmosphere; The function of the diesel engine fuel supply system is to supply diesel and air into the cylinder respectively, form a mixture in the combustion chamber and burn it, and finally discharge the exhaust gas after combustion.

4) Lubrication system.

The function of the lubrication system is to deliver a certain amount of clean lubricating oil to the surface of the parts in relative motion to achieve liquid friction, reduce frictional resistance, and reduce the wear of parts. and the surface of the part is cleaned and cooled. The lubrication system usually consists of a lubricating oil channel, an oil pump, an oil filter, and some valves.

5) Cooling system.

The function of the cooling system is to dissipate part of the heat absorbed by the heated parts in time to ensure that the engine works at the most suitable temperature state. The cooling system of a water-cooled engine usually consists of a cooling jacket, a water pump, a fan, a water tank, a thermostat, etc.

6) Ignition system.

In a gasoline engine, the flammable mixture in the cylinder is ignited by an electric spark, for which a spark plug is installed on the cylinder head of the gasoline engine, and the head of the spark plug protrudes into the combustion chamber. All equipment that can generate electric sparks between the spark plug electrodes on time is called an ignition system, which usually consists of a battery, a generator, a distributor, an ignition coil and a spark plug.

7) Starting system.

In order to make the engine transition from a stationary state to a working state, it is necessary to rotate the crankshaft of the engine with external force first, so that the piston can reciprocate, and the combustible mixture in the cylinder burns and expands to work, and pushes the piston to move downward to rotate the crankshaft. The engine can run on its own and the duty cycle can be automatic. Therefore, the whole process from the crankshaft starting to rotate under the action of external force to the engine starting to idle automatically is called the starting of the engine.

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

The role of the engine is to make the fuel supplied to it burn and generate power. Most automobiles use a reciprocating piston internal combustion engine, which is generally composed of a body, a crank connecting rod mechanism, a valve mechanism, a supply system, a cooling system, a lubrication system, an ignition system (used in gasoline engines), a starting system and other parts.

Power system, power system, brake system, oil circuit, heat dissipation, etc.

What are the parts of a carThe car is usually composed of four parts: engine, chassis, body, and electrical equipment. The role of the engine is to make the fuel supplied to it burn and generate power. Most automobiles use reciprocating piston internal combustion engine (due to the rapid development of modern science and technology, automobile engines in addition to internal combustion engines, there are fuel cell engines, battery motors, etc., we will introduce in the new technology in the future), it is generally composed of the body, crank connecting rod mechanism, gas distribution mechanism, supply system, cooling system, lubrication system, ignition system (used in gasoline engines), starting system and other parts.

The chassis receives the power of the engine, makes the car move, and ensures that the car runs normally according to the driver's control. The chassis is made up of the following parts: Drive train – which transmits the power of the engine to the driving wheels.

It includes components such as clutch, transmission, transmission shaft, and drive axle.

A car is a non-track, unwired vehicle that is mainly driven by its own power and has 4 or more wheels. A car generally consists of four basic parts: engine, chassis, body, and electrical equipment.

A car is a non-track, unwired vehicle that is powered by its own power plant and has 4 or more wheels. The main purpose of a motor vehicle is transportation, i.e. a vehicle that transports people and goods. Cars are distinguished from trains, trams and trolleybuses, tractors for field work, and self-propelled construction machinery.

For the purposes of classification and statistics, two- or three-wheeled motor vehicles, combat vehicles with ** and armor are not counted as cars.

A car is generally composed of four basic parts: engine, chassis, body, and electrical equipment.

"Automobile Construction" is one of the main professional courses of automobile majors in vocational colleges. This book takes the domestic car as the main line, and comprehensively expounds the overall structure of the car and its parts. The main contents include:

Basic knowledge of engine, crank connecting rod mechanism, valve mechanism, gasoline engine fuel supply system, diesel engine fuel supply system, engine lubrication system, engine cooling system, transmission system, driving system, steering system and braking system, etc.

Modern automobiles are made up of multiple devices and mechanisms. The basic structure of automobiles produced by different models, different types and different manufacturers is composed of four parts: engine, chassis, electrical equipment and body.

A car generally consists of an engine, chassis, body, and electrical equipment. The engine is the power plant of the car; The role of the chassis is to support and install the automobile engine and its components;

The body is mounted on the frame of the chassis and is used for the driver, passengers to ride or load cargo.

What is the internal structure of jelly?

The basic structure of a car is generally composed of four basic parts: engine, chassis, body, and electrical equipment.

1. Automobile engine: The engine is the power unit of the car. It is composed of the body, crank connecting rod mechanism, valve mechanism, cooling system, lubrication system, fuel system and ignition system (diesel engine does not have ignition system) and so on.

According to the fuel, there are two kinds of engines: gasoline and diesel engines; According to the working mode, there are two kinds of two-stroke and four-stroke, and the general engine is a four-stroke engine. The working process of the four-stroke engine: The four-stroke engine is a piston reciprocating four strokes to complete a working cycle, including four processes: air intake, compression, work and exhaust.

The four-stroke diesel engine goes through the same process of air intake, compression, work and exhaust as the gasoline engine. But the difference with the gasoline engine is that the gasoline engine is ignited, and the diesel engine is compression-ignited.

Cooling system: generally composed of a water tank, a water pump, a radiator, a fan, a thermostat, a water temperature meter and a water discharge switch. There are two types of cooling for automobile engines, namely air cooling and water cooling.

Generally, automobile engines are mostly cooled by water.

2. The chassis of the car: Transmission train: It is mainly composed of clutch, transmission, universal joint, transmission shaft and drive axle.

Clutch: Its function is to make the power of the engine and the transmission device smoothly engaged or temporarily separated, so as to facilitate the driver to start, stop, shift and other operations of the car. Transmission:

It is composed of transmission housing, transmission cover, first shaft, second shaft, intermediate shaft, reverse shaft, gear, bearing, control mechanism and other parts, which are used for automobile speed transmission and variable output torque. 3. Body: It is composed of frame, axle, suspension and wheels.

Its basic function is to support the quality of the whole car and ensure the driving of the car. Leaf Springs & Shock Absorbers: The role of leaf springs is to maintain an elastic connection between the frame and body and the wheels or axles.

The function of the shock absorber is to cushion the vibration when the car is subjected to vibration impact. The shock absorber is used in parallel with the leaf springs.

4. Electrical equipment: Automotive electrical equipment is mainly composed of batteries, generators, regulators, starters, ignition systems, instruments, lighting devices, audio devices, wipers, etc. Battery:

The function of the battery is to supply electricity to the starter, and to supply power to the engine ignition system and other electrical equipment when the engine is starting or running at low speed. When the engine is running at high speed, the generator generates enough power and the battery can store excess electrical energy. Each single cell on the battery has a positive and negative pole.

The identification method is as follows: the positive pole is engraved with a "+" sign, which is dark brown; The negative pole pillar is engraved with a "-" sign, which is light gray. Starter:

Its function is to convert electrical energy into mechanical energy, drive the crankshaft to rotate, and start the engine. When the starter is used, it should be noted that the starting time of each time should not exceed 5 seconds, the interval between each use should not be less than 10-15 seconds, and the continuous use should not exceed 3 times. If the continuous starting time is too long, it will cause a large amount of discharge of the battery and the overheating and smoke of the starter coil, which is very easy to damage the parts.

The clutch consists of a flywheel, a pressure plate, a clutch plate, a discharging bearing, a discharging fork, a clutch wiring and a clutch pedal. 1.The flywheel is connected to the engine crankshaft to transmit and store engine capacity, while the flywheel has a starter ring gear to start the engine.

2.The pressure plate assembly is bolted to the flywheel, and the main function is to separate the engine power, which is easy for the driver to shift, and if the pressure plate is damaged, the shift operation can not be carried out smoothly.

3.The clutch plate is connected to the gearbox input shaft by an internal spline between the flywheel and the pressure plate, and transmits the engine's power to the gearbox through wear forces.

4.Pressing the clutch pedal on the release bearing will press the release bearing towards the pressure plate, which is separated from the clutch plate by lever action, and the car can be freely put into gear.

5.The separating fork is installed on the gearbox fork shaft, which is mainly used to fix the release bearing, and the split fork can move back and forth on the gearbox housing.

6.The clutch wiring is the accessory that connects the clutch of a car to the driver, and some cars use hydraulic pressure to transmit power.
