根据一项统计数字显示:引擎机件部份的磨损,有超过百分之九十的比例是在冷车发动后三分钟内造成的。汽车究竟为什么需要热车?1、车子长时间停放,引擎内机油又流回底壳内。其时引擎的上半部是处于没有机油,缺乏润滑的状况。大约要在发动后30秒左右,才会因机油泵浦的运转而将机油运送到引擎最需要润滑的活塞,连杆及曲轴等部件。如果发动引擎后就立刻上路,只要不猛踩油门飚车,保持低速运转,其效果是和怠速运转相同的。
According to one statistic, more than 90% of the wear on the engine parts was caused within three minutes after the cold car was started. Why do cars need hot car? 1, the car parked for a long time, the engine oil flow back into the bottom shell. At the time the upper half of the engine was in no oil, the lack of lubrication conditions. About 30 seconds after the start of the oil pump will be due to the operation of the oil delivered to the engine most in need of lubrication of the piston, connecting rod and crankshaft and other components. If the engine immediately after the launch of the road, as long as not to step on the accelerator Biao car, to maintain low-speed operation, the effect is the same as idle operation.
