An animation is fully understood and the intuitive principle of automobile mechanics

1. First of all, the intake of the turbine chamber is connected to the engine exhaust manifold, and the exhaust port is connected to the exhaust pipe. Then the intake port of the supercharger is connected to the air filter pipe, and the exhaust port is connected to the intake manifold. Finally, the turbine and impeller are installed in the turbine chamber and the supercharger respectively, and the two are rigidly connected.

2. The working principle of the four-stroke gasoline engine is to mix air and gasoline in a certain proportion into a good mixture. In the intake stroke, it is sucked into the cylinder. The mixture is compressed and ignited to produce heat energy. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to make a reciprocating linear motion, through the connection The rod and crankshaft flywheel mechanism output mechanical energy to the outside world.

3. As shown in the figure below, Liberate CA61The timing mark of the Type 02 engine is "upper stop point/1~6". When this mark is aligned with the line on the flywheel shell, it means that the piston of 1~6 cylinders is at the upper stop point.

4. There are three versions of the principle of Muniu Liuma, which are introduced as follows: Muniu Liuma is an ordinary unicycle cart.

5. Four: When maintaining a relatively high speed (more than 90 kilometers), the steering wheel must not move randomly. A slight push of the steering wheel will make the car run around, which is easy to cause danger. The steering wheel can only move slightly. Don't relax your hands and don't be too tight.

6. Four-connection rod, bicycle shock absorption system, using the principle of bar to solve the shock-absorbing spring force problem of ordinary direct-connected shock-absorbing system, so that the shock-absorbing spring is vertical and the friction of the fixed shaft is minimized. It is a simple shock-absorbing system solution technical solution.

The working principle of the car engine (illustrated)

The clutch is located in the flywheel shell between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws, and the output shaft of the clutch is variable The input shaft of the speed box.

The internal structure diagram of the engine is shown in the figure below. The internal structure of the engine includes cylinder, piston, crankshaft, connecting rod, camshaft, valve, valve spring, intake duct, exhaust duct and other components.

Engine structure principle The structure of the automobile engine is composed of five major systems and two major mechanisms. Different mechanisms and systems use different accessories, namely: the crank connecting rod mechanism is composed of the body, connecting rod, crankshaft, flywheel and piston.

The working principle of engine 1.Intapt stroke When the intake valve opens and the exhaust valve closes, the piston moves from the upper stop to the lower stop. The volume of the cylinder above the piston increases, resulting in a vacuum degree, and the pressure in the cylinder drops below the intake pressure.

Basic knowledge reserve about automobile engines

The engine body unit is the installation basis of various mechanisms, systems and some other components of the engine, and it is also a crank connecting rod mechanism, gas distribution mechanism, fuel The assembly matrix of the supply system, cooling system and lubrication system. ( 2) Gas distribution mechanism The gas distribution mechanism is composed of valve group and valve transmission group.

Cylinder, 12-cylinder, 16-cylinder, of course, these engines will have L-in-line, V-type and W-type layouts respectively. Like the base we usually see.Originally, it is an in-line three-cylinder engine, an in-line four-cylinder engine, an in-line six-cylinder engine, a v-type six-cylinder engine, a v-type eight-cylinder engine, etc.

Modern car engines mostly use four-cylinder, six-cylinder and eight-cylinder engines.

Automotive engine maintenance knowledge inventory Common engine faults First of all, pay attention to the maintenance of the running-in period, which is the basis for extending the service life of the engine. Be careful of the two common diseases of the engine: 1) Engine wear.

Basic knowledge of automobile engine maintenance Daily maintenance Check the height of the oil surface inside the oil span, and add it to the specified line when it is insufficient. Check the amount of cooling water. Check the stability of the engine connection and the tightness of the accessory device. Keep the engine clean and do the necessary scrubbing.

Car Maintenance Knowledge Engine Chapter Use appropriate quality grade of lubricating oil.For gasoline engines, SD-SF-grade gasoline oil should be selected according to the additional devices and working conditions of the intake and exhaust system; for diesel engines, CB-CD-grade diesel oil should be selected according to the mechanical load. The requirements not lower than those stipulated by the manufacturer shall prevail.

What is the structural principle of automobile engine?

1. The working principle of automobile engines is mainly to convert chemical energy into mechanical energy. The reason why the engine has sufficient power is that it generates kinetic energy by burning the fuel in the cylinder, which makes the piston in the engine cylinder reciprocate, which is also a process of working cycle.

2. Principle of automobile engine: Generally, the engine is four-stroke, and its working principle includes intake stroke, compression stroke, working stroke and exhaust stroke.Simply put, an engine is generally composed of two mechanisms and five systems.

3. As the power source of a car, the engine is like a human heart. However, the size and structure of different people's hearts are not much different, but the internal structure of the engines of different cars is very different. What are the differences in the structure of different engines? Let's learn about it together.

4. The engine is generally four-stroke, and its working principle includes intake stroke, compression stroke, working stroke and exhaust stroke. Most car engines are four-stroke.

5. Basic theory: The gasoline engine converts the energy of gasoline into kinetic energy to drive the car. The easiest way is to obtain kinetic energy by burning gasoline inside the engine. Therefore, the car engine is an internal combustion engine - combustion occurs inside the engine.

piston engine principle

1. Under the strong pressure of gas, the piston moves rapidly down to the dead point to promote the company The pole also runs under the door, and the connecting rod drives the crankshaft to turn. This stroke is the only stroke that enables the engine to work and gain power. The remaining three strokes are prepared for this stroke.

2. The working principle of the engine is: it bears the pressure of burning gas from the top of the piston, transmits the gas pressure to the connecting rod through the piston pin, drives the crankshaft to rotate and output power. The engine consists of the top, the head and the skirt.

3. The intake stroke x0dx0a piston moves from the upper stop to the lower stop under the drive of the crankshaft. At this time, the exhaust valve is closed and the intake valve is opened. In the process of piston movement, the volume of the cylinder gradually increases, and a certain degree of vacuum is formed in the cylinder.

4. Working principle: The farthest position of the top of the piston in the center of rotation of the crankshaft is called the upper dead point, the nearest position is called the lower dead point, and the distance from the upper dead point to the lower dead point is called the piston stroke.

5. The four-stroke gasoline engine mixes air and gasoline in a certain proportion to form a good mixture of the car engine.In the intake stroke, the mixed gas is sucked into the cylinder, and the mixed gas is compressed, ignited and burned to generate heat energy.

engine working principle

Their working principle is as follows: the working principle of gasoline engine: the four-stroke gasoline engine first mixes air and gasoline into a good mixture in a certain proportion, and then inhales the mixture during the intake air stroke. Tank. The mixture is compressed and ignited to produce heat energy.

The working principle of the engine is: the battery provides electrical energy. Under the control of the ignition switch and the starter relay, the starter converts electrical energy into mechanical energy, drives the engine flywheel gear ring and crankshaft to rotate, and the start-up work can be cycled, so that the engine enters a self-operation state.

【Pacific Automobile Network] The principle of gasoline engine: the energy contained in gasoline/diesel is released and converted into the power to drive the car forward. The principle involved is actually to convert internal energy into kinetic energy.

The working principle of automobile engines is mainly to convert chemical energy into mechanical energy. The reason why the engine has sufficient power is that it generates kinetic energy by burning the fuel in the cylinder, which makes the piston in the engine cylinder reciprocate, which is also a process of working cycle.
