但凡有過在北國寒冷冬季駕車經歷的人普遍認為天寒地凍時預熱車能夠延長車的使用年限,對發動機有好處,幾乎是放之四海而皆準的常識。可是剛剛讀到的文章卻剛好跟這個常識相反,反而認為冰天雪地預熱車反而會損害發動機,會縮短汽車的使用壽命,似乎還說的頭頭是道的。特此把該文推介給各位分享如下: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.

其實呀!物為人所用,儘管預熱車反倒不利於延長車的使用壽命,但是預熱車除了出於保養車愛惜車的目的之外,還能夠讓家人或者乘客免於挨凍,一進車裡就春風撲面的,特別是對於老人小孩來講,避免因為溫差太大而遭受風寒也善莫大焉,即便是縮短車的使用壽命有能咋樣,家人或者乘客的舒適才是最該優先考慮的,因為一般來講車能夠吹出熱風最短也需要3,4分鐘,若是沒有上路前預熱車的話,家人或者乘客就不得不忍受至少3,4分鐘的寒冷。
別管那麼多,該出行前預熱車還是預熱吧,反正是舊的不去新的不來嗎!
各位村友,您說呢??
