How much speed can start

Generally speaking, the instant start of the engine can reach 1200-1500 rpm. If the temperature is relatively low, the engine speed will be higher. On the contrary, if the speed is low, the vehicle will easily stall. But on cold start. The speed should not be too high. In order to reduce wear and tear, it is more suitable to start at 2000 speed.

　　

After the car has been parked for a long time, the oil inside the engine will flow back into the oil pan at the bottom of the engine. After ignition, the upper part of the engine is in a state of no oil lubrication, so wait 30 seconds after starting the engine before the oil pump starts to run. Only then will the oil be delivered to the pistons, connecting rods and crankshaft parts of the engine that need to be lubricated. It should be noted that the longer the engine warm-up time, the better. If the car is hot for a long time, the engine will do useless work, and it will waste fuel, which is not conducive to environmental protection. Under normal circumstances, the EFI engine drops from 1200RPM in idling state to 800RPM, and the driver only needs to check the tachometer to get out of the car. During the warm-up period for a long time, it is not allowed to slam on the accelerator, and the engine speed cannot be too high. If the car is not warmed up for a long time, it will increase the wear of the engine parts. Generally, there will be no major problems in a short time, but the life of the engine will be reduced after a long time.
