Automotive cylinder block and cylinder head maintenance skills

1. When removing the residue from the surface under the cylinder head and the upper surface of the cylinder, first block the cylinder hole with a clean cloth to avoid falling into Between the cylinder wall and the piston. When cleaning, pay attention not to damage the surface under the cylinder head and the surface above the gas cylinder. After scraping down, clean the surface under the cylinder head and the surface above the gas cylinder.

2, 5 Clean the scale regularly and ensure that it is cooled with clean soft water. Generally, the engine works for about 1000 hours, and the scale should be cleaned up.6 After the engine is started, the load should be increased after running at low speed for a period of time. 7 Fasten the cylinder head nut, and gradually tighten it in the prescribed order and several times according to the specified torque.

3. If the plane on the shoulder of the cylinder liner table is too high than the plane of the body or too small or lower than the plane of the body, it can be solved by cushioning copper skin at the plane under the shoulder of the cylinder table and the body. The cylinder head bolts of the new or repaired diesel engine should be tightened in time after trial operation and 240-250 hours of operation.

4. Obvious scratches or injuries are not allowed on the plane between the two adjacent combustion chambers.

What are the symptoms of car cylinder fire?

1. The multi-cylinder fire of the car engine is a problem of the ignition system. The ignition system should not only check the spark plug, but also check the wire speed problems such as the ignition coil, as well as the blockage of the oil nozzle (blockage caused by poor quality of gasoline).

2. According to the frequency of fire failure in the working cycle, fire failure can be divided into continuous failure and single failure. Continuous failure fire refers to the phenomenon of continuous failure of fire in the engine operation of the failure cylinder; single failure refers to the failure of fire in the process of engine operation, the failure cylinder sometimes works normally, there are The phenomenon of fire.

3. It is easy to judge that the engine lacks a cylinder. The symptom of missing cylinder is basically that the engine shakes at idle due to unbalanced force.

4. A cylinder of a four-cylinder car is relatively laborious. If the temperature is lower, it means that the cylinder is not working normally. You can also use a screwdriver to short-circuit the spark plug or pull out the cylinder line for a fire break test. After unplugging, if there is no obvious change in the operation of the engine, it proves that the cylinder is not working. Cars without one cylinder and two cylinders can be started in the same way.

5. Insufficient cylinder pressure may cause the vehicle power to decrease. The power drop is a little more serious. It will make the engine shake. Difficult to start.

Does the car have a cylinder

1. The commonly used cylinders for car engines are 3-cylinder, 4-cylinder, 5-cylinder, 6-cylinder, 8-cylinder, 10-cylinder and 12-cylinder.

2. At present, car engines have at least one cylinder, the most of which is Bugatti's w16. Other engines have more than 16 cylinders, but most of them are used for aircraft and other purposes. At present, Bugatti's w16 is the most common engine in cars. I believe that for many people nowadays, the engine is a three-cylinder start.

3. Car knowledge that must be understood. Nookies can blow for a long time. The number of cylinders. The most common number of cylinders in cars is 12. Of course, there are also models with more cylinders, but they are not common. At present, the most common models on the market are 3-cylinder, 4-cylinder and good-cylinder models.

4. Become the guide of the reciprocating movement of the piston. The heat of the piston assembly and its own is transmitted to the cooling water so that the working temperature is appropriate. The cylinder sleeve is a cylindrical part placed in the cylinder hole of the body, and the cylinder head is pressed and fixed.The piston moves back and forth in its inner hole, and there is cooling water cooling outside it.

working principle of automobile cylinder

1. Working principle of cylinder: 1. Single-acting cylinder: The single-acting cylinder has only one chamber to input compressed air, and its piston rod can only be pushed back by external force. Dual-acting cylinder: Dual-acting cylinder refers to a cylinder in which two chambers can input compressed air respectively to achieve two-way movement. The working conditions of the cylinder block are very poor.

2. The working principle of the engine is: the mixed gas of fuel and air is sprayed into the cylinder and ignited. The volume of the mixed gas expands when it burns, and the energy generated pushes the piston to move, and then the up and down movement of the piston is transformed into rotational motion through the crankshaft to make the engine run. Almost all cars adopt This kind of engine.

3. Working principle of cylinder: 1. Single-acting cylinder: The single-acting cylinder has only one cavity, which can input compressed air, and its piston rod can only be pushed back by external force. Double-acting cylinder: Double-acting cylinder refers to a cylinder in which two chambers can be input compressed air respectively to achieve two-way movement. The working conditions of the cylinder block are very bad.

What are the common faults of automobile cylinders?

"pulling the cylinder" is one of the common faults of automobile engines. The so-called "pull" refers to the deep grooves on the inner wall of the cylinder, which makes the piston lose its seal when it rubs against the cylinder wall, resulting in a decrease in the compression pressure of the cylinder and a decrease in engine power.

(1) Fault phenomenon: If the engine speed is unstable, the power is obviously insufficient, and there is a tempering phenomenon, it can be considered that the engine has a fault with too thin mixed gas.

Most of the reasons for this kind of failure are: serious water leakage in the cooling system; the cylinder pad separating the water sleeve from the cylinder is washed away; the main valve of the thermosther falls off; the fan transmission belt is loose or broken; the pump shaft and impeller are loose; and the fan clutch is not working well. Solution: Check the cause of the failure and replace it accordingly.

Common failures and main causes of the engine (1) Abnormal consumption of lubricating oil During driving, the consumption of engine lubricating oil is also more than usual. After driving a certain distance, the dashboard quickly shows that the amount of lubricating oil is insufficient.

I. The failure of the electronic control system, such as missing sensor signal or misalignment, wrong control signal or no signal output, damage to spark plug or ignition coil, failure to ignite, no fuel injection nozzle and line failure, etc.

What does a car cylinder mean?

1. The cylinder of a car, that is, a cylinder, is an empty cylindrical chamber in the engine. There is a piston driven by the pressure or expansion force of the working fluid in the chamber. In some special engines, there are also similar but not cylindrical parts. Number of cylinders: The number of cylinders indicates the number of cylinders of a car engine.

2. A car cylinder is a cylindrical metal part that guides the piston to make a linear reciprocating movement in the cylinder. The air expands in the engine cylinder, converting thermal energy into mechanical energy. The gas is compressed by the piston in the compressor cylinder to increase the pressure. The shell of turbines, rotary piston engines, etc. It is also called "jar".

3. A car cylinder is a cylindrical metal part that guides the piston to move in a straight line in the cylinder.It plays an important role in the engine, increasing the pressure energy of the gas by compressing the gas, converting thermal energy into mechanical energy, and driving the engine to operate normally. The cylinder is divided into reciprocating linear movement type and reciprocating swing type.

4. The arrangement form of the cylinder, as the name implies, refers to the arrangement of each cylinder of the multi-cylinder internal combustion engine. To put it bluntly, it is the queue form discharged by the cylinder on an engine.
