Basic knowledge reserve about automobile engines

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

2. Cylinder, 12-cylinder, 16-cylinder, of course, these engines will have L-in-line, V-type and W-type layouts respectively. As we usually see, there are basically in-line three-cylinder engines, in-line four-cylinder engines, in-line six-cylinder engines, v-type six-cylinder engines, v-type eight-cylinder engines, etc.

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

4. Inventory of automobile engine maintenance knowledge. 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.

5. Basic knowledge of automobile engine maintenance. Daily maintenance. Check the oil surface height inside the oil pan. If it is insufficient, it should be added to the specified line. 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.

6. The engine is the heart of a car. Once the engine fails, the car often has to lie down. The economy, power, emission and environmental protection of the whole vehicle are all related to the operation of the engine.Therefore, maintaining the engine is the first task of maintaining the car.

An animation is fully understood, intuitive automobile mechanical principle

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.

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 connecting rod, The crankshaft flywheel mechanism outputs mechanical energy to the outside.

Assuming that the object is 75 kg fixed, then 2PS can achieve a high level of moving two meters per second, which shows that the greater the horsepower, the stronger the performance of the vehicle, because the weight of the car body is constant, so a car with excellent performance requires high horsepower.

◥Basic working principle of turbocharging system (motion diagram) The animation above is the complete basic working principle of the turbocharging engine. After the previous introduction, readers must have fully understand the principle of turbocharging. In this picture, we add new devices. That's right, that's the cooler.

Mechanical principle of manual transmission cars Manual transmission cars mainly refer to cars equipped with manual transmission. The operator changes the gear meshing position in the transmission through the manual transmission lever, and then changes the transmission ratio, and finally achieves the purpose of changing speed.Therefore, the physical characteristics of the car engine determine the characteristics of the gearbox.

Engine Overall Structure Diagram Engine Lubrication System Structure Diagram Engine Gas Distribution Mechanism Connecting Mechanism Structure Diagram Engine Body Structure Diagram Engine Cooling System Structure Diagram This is the structure diagram of the car engine. If you can't appreciate it yet, please take a look at the next most comprehensive internal structure diagram of the automobile system in history.

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.

Virtual reality engine structure diagram In order to meet the needs of horizontal installation of high-power engines in medium and low-end vehicles, a VR engine has been developed. The six cylinders are arranged at an angle of 15 degrees and installed in a short engine cylinder block that is not too wide. This kind of engine is different from the earlier design, with only one cylinder head.

Engine structure diagram (1) Engine appearance diagram The engine 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.

The engine is a complex machine composed of many structures and systems. Its structural types are diverse, but because the basic working principle is the same, its basic structure is similar. The overall structure diagram of the engine is shown below.

Gasoline engines usually consist of two mechanisms and five systems, while diesel engines lack ignition systems. The structure diagram of the gasoline engine is shown in the figure below. Crank connecting rod mechanism The crank connecting rod mechanism is the core mechanism of the engine to realize thermal function conversion.

The throttle valve is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it will be mixed with gasoline into a combustible mixture, thus burning the workmanship.It is connected to the air filter above and the engine cylinder block below, which is known as the throat of the car engine.
