短时间warm up还是有好处的

So, when you start that cold engine, it's essentially running without lubrication. If you start up and immediately put a load on the engine, things could get damaged. It's just not ready to go. Take a minute or two to get that oil pumping around before putting any load on the engine, and your pistons and camshafts and turbos and other spinning, moving bits will be much, much happier.

• 关键是坐在车里预热，人太冷了受不了。如果有遥控热车。我还是喜欢车子里暖洋洋时再坐进去。 -coorslight969- ♂ (0 bytes) () 01/22/2016 postreply 09:48:13

• 遥控热车是好，多花些银子方便，我这里不冷，但是走到车前几分钟打着方便 -soccer88- ♂ (0 bytes) () 01/22/2016 postreply 10:10:54

• 觉得开着风扇下热车水温表上升反而慢，还是行车5分钟以后再开风扇更有效率 -obamacome- ♀ (0 bytes) () 01/22/2016 postreply 20:20:53

• 我感觉发动机启动十几秒内机油就足够散布了，刚启动那一刹那感觉比较生硬。发动机怠速也一秒钟十转呢。 -二胡一刀- ♂ (0 bytes) () 01/22/2016 postreply 12:02:42

• 是滴，汽车的热风大多来自引擎的余热，大冷天的谁愿意坐在冰箱里开5分钟？ -US_CAR.- ♂ (0 bytes) () 01/22/2016 postreply 12:09:56

• 某些人插进钥匙，点火，倒车，在一秒钟搞定。多次提示，给发动机预热那怕半分钟。却不听。 -leslieking- ♂ (0 bytes) () 01/22/2016 postreply 15:38:51

• 看新车手册只说天冷启车不要轰油门加速，也不建议怠速下热车 -obamacome- ♀ (0 bytes) () 01/22/2016 postreply 20:12:16

• 至少要等到fast idle 结束再挂档起步。 -US_CAR.- ♂ (0 bytes) () 01/22/2016 postreply 21:08:09

• 冬天了，已听过很多早晨热车而被盗窃的报导，有的回屋5、6秒钟高档车就被开走了，哈哈 -obamacome- ♀ (0 bytes) () 01/22/2016 postreply 20:06:09
