但凡有过在北国寒冷冬季驾车经历的人普遍认为天寒地冻时预热车能够延长车的使用年限，对发动机有好处，几乎是放之四海而皆准的常识。可是刚刚读到的文章却刚好跟这个常识相反，反而认为冰天雪地预热车反而会损害发动机，会缩短汽车的使用寿命，似乎还说的头头是道的。特此把该文推介给各位分享如下：Here’s Why You Shouldn’t Warm Up Your Car In The Winter http://www.msn.com/en-ca/autos/ownership/here%e2%80%99s-why-you-shouldn%e2%80%99t-warm-up-your-car-in-the-winter/ar-BBQfn1V?li=AAggNb9&ocid=UE12DHP
When it's frigid outside and you have to drive to some sort of destination, there's only one solution to fighting the ridiculous cold: Warm up the car. Just start it up a few minutes before hopping in, giving your cabin and your engine time to warm up before hitting the road. Plus, it's supposed to be good for the life of your engine, right?
Wrong! Warming up your car in winter before driving it is actually terrible for your engine. According to Popular Mechanics, driving your car right away is the fastest way to warm up your engine, and will actually prolong the life of your engine instead of letting it sit idly before driving. Answering the old question on whether you should warm up your car.
The reasoning has to do with how modern internal combustion engines work. By letting your car sit to warm up, it's actually putting extra fuel into the combustion chamber, which can get onto your cylinder walls. Because gasoline is an excellent solvent, too much on your cylinder walls can dissolve the oil that lubricates your cylinders, leading to shorter life on crucial components.
Of course, hopping into a cold car is never a fun task. Although driving your car will actually warm up your engine faster than idling, it still means driving for a period of time in a cold vehicle. And, it also means dealing with the frost on your car windows before they warm up. Fortunately, you can easily defrost your windows in 30 seconds with this simple car window defrosting trick.
Now if warming up your car in winter is actually terrible for your engine, why did people even do this in the first place? According to USA Today, this practices comes from the use of cars with carburetors -- a fuel delivery system that preceded fuel injection that did require warming up beforehand. Some people would have to wait up to 10 minutes before even getting into a car, deeming it safe enough to drive with a warmed up engine. Nevertheless, cars and technology have drastically changed since the 1960s, which means this old practice is no longer required.
Instead, just give it a minute and start with an easy drive. Flooring it right away obviously isn't the solution, but easing yourself into a drive will help to warm your engine faster than you originally thought.
Haven't prepped your car for winter? Here's how to get your car winter ready, as well as the things you need in your winter car survival kit.
其实呀！物为人所用，尽管预热车反倒不利于延长车的使用寿命，但是预热车除了出于保养车爱惜车的目的之外，还能够让家人或者乘客免于挨冻，一进车里就春风扑面的，特别是对于老人小孩来讲，避免因为温差太大而遭受风寒也善莫大焉，即便是缩短车的使用寿命有能咋样，家人或者乘客的舒适才是最该优先考虑的，因为一般来讲车能够吹出热风最短也需要3,4分钟，若是没有上路前预热车的话，家人或者乘客就不得不忍受至少3,4分钟的寒冷。
别管那么多，该出行前预热车还是预热吧，反正是旧的不去新的不来吗！
各位村友，您说呢？？
