Q:What's the use of an oil pump in an automobile engine?
Give the oil pressure so that it can be recycled to the point where it needs lubrication
Q:The function of the oil pump screen is troublesome
Hello, just filter the oil and the dirt in it
Q:Volkswagen Polo pump for heating lamp and light machine
Sometimes the oil lamp is bright because the oil sensor plug is not working well and the wires are loose and sometimes light.
Q:What is the effect of excessive oil on the oil pump?
Too much oil, will increase the rotational resistance of the crankshaft, reduce the output power of the engine, and the excess oil from entering the combustion chamber in the combustion, burning oil, causing the vehicle to take the blue smoke, and increased fuel consumption, oil residue after combustion (the main component is carbon, very hard) will accumulate in the combustion chamber wall. To reduce the space of the combustion chamber, thereby reducing the engine compression ratio, at the same time, will accelerate the wear of cylinder and piston so as to reduce the service life of the vehicle.
Q:Engine oil pump is blocked when the chain would ring
Hello, not only will sound, and other components will ring, the oil pump blocked, the oil lamp will be lit, not recommended to travel as soon as possible to the professional maintenance factory inspection, I hope my answer will help you
Q:What's the reason that I changed the new oil pump instead of the engine oil?
Did you try the oil pump before loading?
Q:Single cylinder diesel engine crank bearing lock replacement, cause oil pump wear, replacement
The cause of this phenomenon is the severe wear of the crankshaft journal or the smooth failure of the crankshaft journal! You don't know what type of diesel engine, if the oil channel Changchai ZS1110 and 1115 double rolling type words to check the main bearing cap is worn, because the main bearing cap of oil on the road directly to the crankshaft oil supply, after the formation of wear caused by leakage of lubricating oil pressure machine high temperature, bad to smoke. Troubleshooting: check crankshaft and bearing cap for serious wear and tear. Replace if necessary.
Q:In the 1 to 2 seconds when the vehicle is started, does the oil pump inject engine oil into the engine?
The first problem: the oil pump and the engine crankshaft movement synchronization, start the machine work a few seconds, the oil pump oil pump in the same way, just because the empty oil engine cooling period, not immediately to the oil pump in place.The second question: basically, there is no such operation necessary, when the engine does not run, the oil pump will not pump out oil, reduce the wear and tear of little effect, but more start will increase the wear of the starter.
Q:Automobile engine oil pump does not leak pressure, which causes oil seal ring to leak seriously. What is the trouble?
Have you tested the oil pressure gauge? How high is the maximum oil pressure?In general, if more than 4kg, then it is too high, and generally within the normal 3kg, followed by what you car, what the engine ah?
Q:Automobile oil pump fault
Such a problem can arise. The oil pressure is too high, and the oil filter is opened by "drum". The reason is that the oil pump pressure limiting valve [pressure relief valve], resulting in a failure, can not normally open at high pressure caused by pressure relief
