Where is the all-fired engine respirator

The bottom of the crankcase. According to the official website of Jiangdong, the Jiangdong 3100 diesel engine respirator is at the bottom of the crankcase. The respirator is the organ used by the engine to breathe, which is mainly used to maintain the pressure balance between the inside and outside the high-temperature body activated during work.

On the cover of the crankcase. 4 The steel oil machine respirator needs to be installed in the crankcase cover. The four-cylinder engine, also known as the four-cylinder engine, is a machine that can transform one form of energy into another more useful energy.

The crankcase respirator is generally installed on the valve cover, refueling port, gear chamber cover and fuselage side door cover, mainly to ensure the pressure relief of the crankcase, because when the engine is running,The piston moves reciprocating, and the gas running under the piston will cause the pressure of the crankcase to rise, causing oil leakage. The respirator can maintain the pressure balance inside and outside the crankcase.

-192 diesel engine respirator is on the crankcase cover, the respirator of Changchai 195-1125 diesel engine is on the side of the gear chamber cover, and the Shandong series diesel engine respirator is also on the crankcase cover.

Just call it the refueling port. It's not a respirator on the side of the engine. Some are on the left and some are on the right.

function: (1) The intake and exhaust branch pipe of the diesel engine respirator is two independent pipes, and the peach shaft (eccentric shaft) can be rotated to open or close the valve. ( 2) When the air chamber is opened, the intake pipe inhales air and mixes with fuel. At this time, the piston is at the upper stop point, the peach shaft rotates again, and the intake and exhaust valve is closed.

The working principle and function of diesel car respirator

Because the high-pressure gas in the cylinder will pass Through the gap between the piston and the cylinder wall into the crankcase, the pressure of the crankcase will inevitably increase gradually. The function of the respirator is to control the pressure in the crankcase so that it is not too high. At the same time, separate and discharge the oil and fuel steam in the exhaust gas.

The working principle of the automobile drive bridge respirator is to open the crankcase when there is exhaust gas pressure and close it when there is no pressure to exhaust the crankcase to maintain negative pressure.

The function of the respirator is to prevent the crankcase of the engine from generating high pressure, which plays the same internal and external pressure as the engine. If the internal pressure is too high, oil will burn. As for the function of the cover, it is very clear, dustproof.

When the engine is working, the temperature will reach at least 80 degrees. The internal oil and gas are mixed at high temperatures to produce exhaust gas, and the internal gas pressure is getting higher and higher, so it must be discharged. At this time, it is discharged through the respirator to ensure that the internal pressure of the engine exceeds the standard.

Where is the engine crankcase respirator of the 6-cylinder engine, what is its function, and the inflator has...

1. The crankcase respirator is generally installed on the valve cover, refueling port, gear chamber cover, and the side door cover of the fuselage, mainly to ensure the crankcase pressure relief, because when the engine is running, the piston Reciprocating movement, the air running under the piston will cause the pressure of the crankcase to rise, causing oil leakage. The respirator can maintain the pressure balance inside and outside the crankcase.

2. The main function of the crankcase respirator is to prevent the deterioration of the engine oil. Prevent the leakage of crankshaft oil seal and crankcase gasket. Prevent all kinds of oil vapor from polluting the atmosphere. Crankcase ventilation includes natural ventilation and forced ventilation. Modern gasoline engines often adopt forced crankcase ventilation, also known as the PCV system.

3. The gas extracted from the crankcase can be directly introduced into the atmosphere, which is called natural ventilation.This ventilation method is simple in structure and easy to use, but the introduction of combustible mixed gas and oil vapor into the atmosphere is easy to pollute the atmosphere, so modern engines are rarely used. There are two types of natural ventilation: ordinary ventilation and respiratory ventilation.

4. The crankcase is opened when there is exhaust gas pressure, and the exhaust gas is discharged outward. When there is no pressure, it is closed so that the crankcase maintains negative pressure, the oil is not easy to leak, and the oil will not be discharged into the cylinder liner. Function: (1) The intake and exhaust branch pipes of the diesel engine respirator are two independent pipes, and the peach shaft (eccentric shaft) can be rotated to open or close the valve.

5. The function of the respirator is to prevent the crankcase of the engine from generating high pressure, which plays the same internal and external pressure as the engine. If the internal pressure is too high, it will burn oil. As for the function of the cover, it is very clear, dustproof.

What's wrong with the sizzling sound of the internal structure of the SINOTRUK engine respirator?

This is generally caused by the slippage of the belt; there will also be a sharp sound of dry friction of metal parts when the engine is running, which is generally the cause of damage to the bearings of the generator, water pump and steering booster pump; if it is the sound of engine running air leakage, it may be that the exhaust system is blocked, the vacuum tube is leaking or broken. The result of cracking.

The oil leakage or large amount of oil dripping of the vehicle engine respirator (lower exhaust) is mainly caused by the loose sealing of the valve or the serious wear of the four supporting equipment.

It may be caused by the cylinder running out of air, the reason is that the four supporting equipment may not be well run-in, or the piston ring of one of the cylinders may be opposite;The inspection method is not difficult. It can be seen intuitively by measuring the pressure of each cylinder separately; the lowest pressure is the problem.

Principle: The crankcase is opened when there is exhaust gas pressure, the exhaust gas is discharged out, and it is closed when there is no pressure, so that the crankcase maintains negative pressure, the oil is not easy to leak, and the oil will not be discharged into the cylinder liner.

During the compression and expansion of the diesel engine, a large amount of compressed gas will enter the crankcase through the small gap between the piston ring and the cylinder liner, increasing the exhaust pressure of the crankcase. The main phenomenon is that the exhaust under the respirator is serious, and the diesel engine lacks power. Insufficient, there may also be a smoke of supervision.

Is the crankcase respirator of the engine oil-gas separator

The part of the engine crankcase breathing port or exhaust pipe.According to the Baidu Encyclopedia query, the oil-gas separator is also called the exhaust valve, which is also called the pressure control valve. The function of the oil-gas separator is to separate the oil in the gas discharged from the crankcase and reduce the oil discharge from the crankcase breathing port to the outside of the engine.

The respirator is also called an oil-gas separator. When the engine is running, the crankcase is under high pressure, releasing part of the exhaust gas and oil vapor. Part of the exhaust gas is discharged into the air along the pipe. After part of the oil vapor cools down, it returns to the oil span.

The function of the oil-gas separator is to separate the oil discharged from the crankcase and reduce the oil discharged from the crankcase breathing port to the outside of the engine. That is to say, if the oil-gas separator is broken, the oil steam will enter the intake pipe, and then enter the cylinder to burn, and the vehicle will burn the oil. If the vehicle burns oil and the fuel consumption increases, a large amount of blue smoke will come out of the vehicle exhaust.
