Q:What's the function of the engine oil pump?
The function of the oil pump is to send the oil to the friction parts of the engine, so that the engine oil is circulating in the lubrication road to ensure the engine to be well lubricated. The oil pump is mostly gear pump. It consists of gear pump body and so on. When the engine works, the camshaft drives the drive gear of the pump body. The gear swing oil flows along the inner wall of the pump from the oil inlet to the oil outlet, forming a low pressure to generate suction, and the oil in the oil box is sucked into the oil inlet. And the oil at the mouth of the oil more and more, and therefore increased pressure, oil will be pressed to each of the friction parts, the realization of forced lubrication.
Q:What part does the electromagnetic valve connect to?
The external solenoid valve is installed on the oil pump, and the oil pump solenoid valve is used to realize the oil pump two or multistage oil pump pressure, and is in the oil pan, but the position is the external of the engine.Built in solenoid valve installed in the oil pump, usually in the main oil road and oil pump, controlled by ECU, installation position in the cylinder.
Q:What is the oil pump on the car? If it is blocked, how can I solve it?
Providing lubricating oil and lubricating pressure for each friction pair of the engine
Q:Are the engines all organic?
There are some motorcycle engines without oil pumps, which are "splash lubrication"".
Q:4Y engine oil pump, okay? Still lifting the engine?
You don't need to lift the engine, but the 4Y engines are usually chain. You need to make the timing right.
Q:The working principle of gear type oil pump
Gear pump comprises a driving shaft, a driving gear, a driven shaft, a driven gear, a shell body, two the same number of teeth of gear meshing, installed in the shell, and the shell gear radial and end clearance is very small. The driving shaft is connected with the driving gear key, and the driven gear is sleeved on the driven shaft.When working, the driving gear drives the driven gear to rotate in reverse direction. The two gear rotates in full gear tooth between the oil pump shell along the wall of the inlet oil cavity to the oil chamber into the oil chamber, one side produced out of gear meshing and the vacuum oil is continuously carried out, the oil sump oil under atmospheric pressure by entering into the oil strainer in the cavity, the oil chamber side as into gear meshing and oil have been produced into compression, oil is pumped to a certain pressure
Q:What are the causes of motorcycle engine oil pump damage?
One: the quality of gasoline plus 90 oil, do not say that the damage to the oil pump, the vehicle engine damage is greatTwo: too much oil refueling, the pump burden is too large, too much overheating of the engineThree: the quality of the oil, the better the oil on the engine wear less, but ordinary 125 is not necessary to be so goodFour: the oil use time normally every 3000 to 5000 kilometers should change the old oil, does not change the old oil in the iron and the thicker oil itself will have a great damage to the oil pumpFour: the normal wear and tear of the machine, needless to say, is a bad day for everything
Q:Does the motorcycle oil pump break down and cause the engine oil to burn?
The pits are ready for oil, lubrication, and burning
Q:I put down the motorcycle engine oil pump cleaning up after the cylinder head not to how oil ah
Fill the oil pump with oil, and put it in it. You can't get the oil out of it
Q:Will it clog up the oil pump by cleaning the engine oil which is strong enough to clog up the oil circuit?
If the engine is too much carbon deposits, the use of such properties of oil, it is true that such a situation can occur. The first is blocked by the oil pump filter. The oil passages are not blocked, because carbon deposits are filtered first by the filter. Sludge is capable of entering the oil passages.
