The type of car engine is as follows: 1. According to the working mode of the air intake system, it is divided into four types: natural aspiration, turbocharged, motorizing, and dual supercharged. 2. Pistons Movement: It can be divided into rehabilitation internal combustion engines and rotating piston engines. 3. cylinder arrangement type: inline engine, V -type engine, W -type engine and horizontal opposite engine. 4. Press the number of cylinders: can be divided into single -cylinder engine and multi -cylinder engine. Most of modern cars use three -cylinder, four -cylinder, six -cylinder, and eight -cylinder engine. 5. Different from the cooling method: can be divided into water -cooled engines and air -cooled engines. Water -cooled engines are widely used in modern car engines due to their uniform cooling, reliable work, and good cooling effect. 6. Press the number of strokes: can be divided into four -stroke internal combustion engine and two -stroke internal combustion engine. The four -stroke internal combustion engine is widely used in cars. 7. Classified by oil supply: carburetor engine, electric injection engine, and in -cylinder direct injection engine.

First look at the most common engine parameter -engine displacement. The engine displacement is the sum of the operating volume of each cylinder of the engine, which is generally represented by liters (L). The operating volume of the cylinder refers to the gas volume swept by the piston from the top to the lower point, also known as a single cylinder displacement, depending on the cycle diameter and the piston itinerary. The engine displacement is a very important engine parameter. It can more represent the size of the engine than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the exhaust volume. Generally speaking, the greater the displacement, the greater the output power of the engine.

Engine (Engine) is a machine that can convert other forms into mechanical energy, including internal combustion engines (to rehabilitation engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is suitable for both power occurrence devices or the entire machine (such as gasoline engines, aviation engines) including power devices. The engine was first born in the UK, so the concept of the engine also originated from English. Its original meaning refers to the "mechanical device that generates power."

The car chassis includes the following: 1. The chassis is the main component of the car. , Turn on the support device, half -axis, main subtraction, and chassis regulatory system; 2. For an intermediate car, these parts account for 20%of the total weight and 15%of the production cost; 3. The chassis is vehicles and pavement surfaces. The connection part can achieve the function of vehicle driving through it, mainly including: the transfer of driving torque (overcoming driving resistance and acceleration), braking, clutch and accelerated pedal control steering and vibration reduction.
