冷天开车前warm up不但不需要甚至有害

In frigid temperatures, it’s a common practice for many drivers to let their cars warm up for a few minutes before hitting the road. Some vehicles even have a preset feature that lets drivers start their cars remotely.
But a VERIFY viewer wants to know if doing so can potentially hurt your car’s engine.
。。。
In a blog post on its website, Smart Motors Toyota says letting your car idle in cold temperatures can shorten the life of your engine by stripping away oil from the engine’s pistons and cylinders — two critical components that help your engine run, Stephen Ciatti, Ph.D., principal engineer for battery systems at PACCAR, told Business Insider in 2016.
。。。
Firestone and Smart Motors Toyota both say that most cars made before 1980 did need to “warm up” when it was cold out. This is because older model cars had carburetors that regulated the air-fuel mixture within the engine and could not accurately adjust the air-to-fuel ratio in cold weather.
But times have changed since the 1980s 。。。

不光是发动机需要热起来,不然热效率不强,费油。变速箱也许要热起来,不然加速很差。
司马光在《资治通鉴》中说日本人:'知小礼而无大义,拘小节而无大德。重末节而无廉耻,畏威而不怀德。强必盗寇,弱必卑伏'。
康熙皇帝在《康熙朝起居注》中这样评论日本人:“倭子国,最是反复无常之国。其人,甚卑贱,不知世上有恩谊,只一味慑于武威……故尔,不得对其有稍许好颜色。”
