How to measure the cylinder on the car?

1. Cylinder diameter × stroke = displacement per cylinder, and then multiplied by the number of cylinders is the displacement of the engine.

2. Operating specifications of the cylinder gauge: x0dx0ax0dx0a installation and proofreading of the cylinder gauge x0dx0a(1) According to the standard size of the measured cylinder, select the appropriate connecting rod. After installation, do not tighten the fixing nut for the time being.

3. Make the measuring rod of the measuring cylinder meter in vertical contact with the i-cylinder wall. First, slide the cylinder gauge down along the cylinder wall to read the maximum swing of the pointer to the right, which is the maximum wear of the cylinder.

4. Measurement method and numerical determination. Before measuring the cylinder pressure, all spark plugs should be removed and the measuring gauge back to zero should be touched at the spark plug seat hole of the tested cylinder (some cylinder pressure gauges are screwed on the spark plug hole).Start the engine, observe and remember the value indicated by the first beating of the needle.

5. Here I have the following suggestions. Self-measurement of the size first needs to calculate the degree of the worn cylinder. Generally speaking, the diameter is between 0.1mm and 0.2mm, and it is necessary to determine its size plus its wear margin.

Car cylinder [What is a cylinder]

1. A car cylinder, 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. The part of the shape. 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 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.

3. 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".

4. The cylinder of a car is a cylinder, which is a cylindrical empty chamber in the engine. There is a piston driven by the pressure or expansion force of the working fluid, a similar but non-cylindrical part in some special engines.

What does the number of car cylinders mean?

1. The number of cylinders of a car represents displacement and power. The number of cylinders refers to the number of cylinders commonly used in automobile engines, including 12 cylinders.

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

3. It is the place where the piston is placed. The more cylinders there are, the greater the power of the car. For example, the fastest car in the world, Bugatti Veyron has 16 cylinders, cars like Ferrari have 12 cylinders, and ordinary cars running on the street have 4 or 6 cylinders, which is what we call L4. V6, hehe.

4. What does the cylinders often mean? The cylinder refers to the cylinder of the engine, and several cylinders refers to the several cylinders of the engine. The cylinder is the power source of the car. Gasoline or diesel burns in the cylinder, and the expansion gas drives the related machinery to move, which is converted into the power to push the car forward. The more the cylinders produce, the greater the energy and the stronger the thrust.

5. How many cylinders means how many cylinders there are in the engine, that is, the more cylinders the piston works, the stronger the engine, the greater the exhaust volume of the car.Nowadays, most engines are made up of one or several cylinder blocks arranged in a certain form. A few cylinder blocks mean that the engine has several cylinders.

What's the matter with the air leakage of the car cylinder?

1. The piston ring and cylinder are seriously worn or the piston ring is stuck, resulting in air leakage. Parts can be replaced to solve the problem. If the spark plug gasket is damaged or the surface is sticky with impurities, forgetting to install the spark plug gasket will cause air leakage between the spark plug gasket and the cylinder head. Just replace the gasket to solve the problem.

2. The leakage of the cylinder seal is caused by a variety of reasons, such as leakage of the dustproof seal, impurities or scratches on the surface of the shaft, damage or abrasions of the seal, scratches or poor assembly of the wall seal, incorrect model of the seal, incorrect assembly, and deformation of the sealing position of the cylinder end cover.

3. [Cause of engine leakage] In the long-term use of the engine, due to the wear of the cylinder piston parts, the wear and ablation of the valve and valve seat, and the warping of the cylinder block and cylinder head sealing surface, the air leakage of the cylinder will increase and the sealing performance will decrease, resulting in a decrease in engine power and fuel consumption. Add.

4. Under normal circumstances, engine air leakage is caused by serious wear of the piston ring, resulting in the inability to seal the piston ring, resulting in air leakage in the cylinder. You need to disassemble the cylinder, replace the piston ring of the same model, and then install and reset the cylinder.

5. During the long-term use of the engine, the wear of the cylinder piston parts, the wear and erosion of the valve and valve seat, and the warping of the cylinder block and cylinder head sealing surface may all cause the engine cylinder leakage. When you find an abnormality in the engine, pay attention to whether the sound is abnormal.

6. [Cause of engine air leakage] In the process of long-term use of the engine, due to the wear of the cylinder piston parts, the wear and erosion of the valve and valve seat, and the warping of the sealing surface of the cylinder block and the cylinder head, the amount of air leakage of the cylinder increases and the sealing performance decreases, resulting in a decrease in engine power and fuel consumption. Add.

Automotive cylinder block and cylinder head maintenance skills

When removing the residue from the lower surface of the cylinder head and the upper surface of the gas cylinder, first block the cylinder hole with a clean cloth to avoid falling between the inlet 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.

5 Clean up 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.

If the plane on the shoulder of the cylinder liner is too higher than the plane of the body or too lower than the plane of the body, you can put copper skin on the plane under the shoulder of the cylinder liner and the body to solve the problem. 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.

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

The staining method is to spray the staining penetrating agent on the inspected part and wipe it dry after a while. If the penetrating agent penetrates into the interior, it means that there is a crack in that place.Cracks in the cylinder block and cylinder head are generally repaired by epoxy resin glue, which is mostly suitable for the repair of some cracks in the water sleeve.

The deformation of the cylinder head of a car can be repaired by polishing. However, every time the cylinder head is polished, the thickness of the cylinder head becomes thinner, the volume of the combustion chamber becomes smaller, and the compression ratio increases, resulting in engine explosion. Or replace the new engine cylinder head directly. The deformation of the cylinder head will cause a variety of problems, including oil burning, decreased power, increased fuel consumption, etc.
