How long is appropriate for vehicle warm-up time?
1 Answers
In winter, the warm-up time for a car should be controlled within two minutes, while in summer, 30 seconds to one minute is sufficient. Here is some relevant information: 1. Transporting engine oil: After the vehicle has been parked for a long time, the engine oil flows back into the oil pan, leaving the upper part in a state of insufficient lubrication. Warming up the car transports the oil to the pistons, connecting rods, and crankshaft components that need lubrication. 2. Vaporizing the oil: When the engine has not reached its operating temperature, the fuel supply system, due to the low temperature, cannot effectively vaporize the gasoline completely. 3. Lubricating gears: When the car is cold, the gear oil flows to the lower part of the transmission. Only when the car is moving does the operation of the gears bring up the gear oil from the bottom to lubricate the upper part.
