Question:

In the 1 to 2 seconds when the vehicle is started, does the oil pump inject engine oil into the engine?

First question: I mean the turn key, the engine doesn't work, the seconds when the starter works. Does the oil pump inject oil into the engine during this time? Or wait until the engine is fully started to inject lubrication?The second question: because now the cold weather, I saw a forum of northeast riders turn the key to the starter operation recommendations for 1-2 seconds, then later normal launch, said that this can reduce engine wear, do this operation is correct?

Answer:

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.
Yes, the oil pump follows the crankshaft
1, the pump is driven by the engine, has not formed the oil pressure, ah, fuel injection ah. 2, no oil pressure, lubricating oil does not work, using the starter to drive the engine, and more can not help lubrication, you think it is a motorcycle ah?. In addition low temperature starting, oil pressure has not reached, and the oil temperature is low, poor mobility, no fuel injection, in order not to affect the lubrication oil does not flow through a filter, so the oil containing impurities, if the vehicle is harmful to the engine oil pressure, so only the lamp before driving, hot to hot oil and reached the normal working temperature.
