What is the function of automobile engine cylinders

[Pacific Automobile Network] The function of engine cylinders is to connect various cylinders and crankcases into one, which is to install The supporting skeleton of pistons, crankshafts and other parts and accessories is one of the main parts of the engine.

The function of the engine cylinder block is the main body of the engine, which connects each cylinder and crankcase into one, and is the supporting skeleton for installing pistons, crankshafts and other parts and accessories. The cylinder block is one of the main parts of the car engine.

The function of the cylinder is to transform energy. The air and fuel inhaled by the car are mixed in the cylinder to ignite the combustible mixture by sparking (gasoline engine) or pressure combustion (diesel engine). When the combustion and expansion of the combustible mixture, high pressure is generated, which drives the piston in the cylinder and converts the chemical energy of the fuel into mechanical energy. So as to drive the car.

[Pacific Automobile Network] The function of the engine cylinder block is to connect various cylinders and crankcases in the car, mainly to install the supporting skeleton of pistons, crankshafts and other parts and accessories.The working conditions of the cylinder block are very bad. It has to withstand the sharp changes in pressure and temperature during combustion and the strong friction of the piston movement.

Therefore, it must have the following functions: sufficient strength and rigidity, small deformation, and ensure that the position of each moving part is accurate, the work is normal, and the vibration noise is small. It has good cooling performance, and there is a cooling water sleeve around the cylinder to make the cooling water absorb heat. In order to ensure that the cylinder block has enough service life and is wear-resistant.

The cylinder head is used to seal the upper part of the engine and form a combustion chamber with the cylinder block. There is a waterway connected to the cylinder block to cool the engine. The valve components and spark plugs are installed on the cylinder head. The cylinder liner of the cylindrical piston diesel engine withstands the side thrust of the piston, which becomes the guide for the reciprocing movement of the piston.

What are the arrangements of the cylinders of the engine?

At present, the arrangement of engine cylinders is divided into the following types: L-type in-line, V-type arrangement, horizontal alignment (B-type) and R-type rotor engine. L-type inline L is the abbreviation of inline. Generally, there is an Arabic numeral at the end, which represents the number of cylinders. For example, L4 is an in-line 4-cylinder.

At present, the mainstream engine cylinder arrangement form: L-type in-line, V-type arrangement, W-type arrangement, horizontally opposed engine.

Inline engine Inline engine is a relatively common type, which is represented by the letter L. For example, L4 represents an inline four-cylinder engine. This layout means that all the cylinders of the engine are shot at the same angle, and only one cylinder head is used, and the structure of its cylinder block and crankshaft is also in the cylinder arrangement. The simplest way.

What is a cylinder? What are the types of cylinders?

1. The cylinder is composed of cylinder, cylinder head, piston, piston rod and seal, etc. According to the type of cylinder of the relevant engine, it is roughly divided into four types! They are L-type engine, v-type engine and w-type engine, as well as horizontally opposed engines.

2. Fixed cylinder: the cylinder block is fixed. ( 2) Shaft pin cylinder: The cylinder block can swing around the fixed shaft pin at a certain angle. ( 3) Rotary cylinder: The cylinder block is usually fixed on the spindle of the machine tool, and the spindle of the random bed can be rotated together. This cylinder is often used in the pneumatic chuck of the machine tool.

3. The function of making its front and rear movement; and connecting the mechanism to make a straight line, rotation and clamping and other movements; the categories of cylinders include: jig cylinder, blocking cylinder, sliding table cylinder, double-axis cylinder, rodless cylinder, sliding seat cylinder, rotary cylinder and mechanical clamp, etc.

4. The pneumatic actuator that converts the pressure energy of the compressed gas into mechanical energy in the pneumatic transmission. There are two types of cylinders: reciprocating linear motion and reciprocating swing (see the figure). Do it back and forthLinear cylinders can be divided into four types: single-acting cylinder, dual-acting cylinder, diaphragm cylinder and impact cylinder.

5. Abstract: The cylinder block is the main body of the engine. The structural forms of the cylinder block include general cylinder block, gantry cylinder block and tunnel cylinder. So what are the functions of the cylinder block? What are the structural forms of the cylinder block? Let's find out together.
