One question has always been controversial. Is it necessary to warm up the car when it starts in the morning? Everyone has a lot of opinions on the issue of starting hot or not hot cars. Some people say that there is no need to warm the car, and some people insist that it must be good for the engine. Is hot car necessary in daily life? Today I will tell you in detail!
The cold winter is here, the sad thing is whether your car is afraid of cold
Statistics show that more than 90% of the wear of the engine parts is caused within three minutes after the cold car is started. Therefore, idling hot cars on the spot in the cold winter can easily damage the engine.
How should it be hot?
The right way to hot car should be
Get on the road 30 seconds to one minute after the car starts
But at this time, do not drive at high speed, you should keep the car at low speed, the speed does not exceed 3000 ~ 3500 rpm, generally 2000 rpm. Otherwise, the engine and transmission will be severely worn. At this time, as long as the engine temperature rises to the normal working temperature, normal driving can be resumed again.
- What is “traffic warm-up”?
Answer: “Drive warm-up” refers to a hot-car way that allows the lubrication system and cooling system to move by themselves during the driving of the vehicle.
- After the vehicle starts, are there any restrictions on the speed?
Answer: There are no too many restrictions, and normal driving is just fine, but at this time the engine has not reached the standard operating temperature. Try to avoid rapid acceleration and high speed. This process actually takes only three to five minutes.
- It’s cold in winter, don’t you need hot car in place?
Answer: Yes, the current engine processing technology is not as good as before, and the engine oil performance has also been significantly improved, so in-situ hot cars are not needed, and “travel warm-up” is also applicable. Just considering that the car is too cold in the winter and needs warm air, the idle hot car time can be extended appropriately.
- In winter, can the throttle be increased in order to raise the engine temperature as soon as possible?
Answer: No. Blasting the throttle means high speed, and the engine wear will be aggravated in the cool state, and it will also affect the engine carbon deposit, fuel consumption, and exhaust emissions.
- Is it applicable to vehicles parked for a long time?
Answer: Not necessarily. For vehicles parked for a long time, most of the oil returns to the oil pan, and immediately after starting the car, some engines may also make a “click” sound due to lack of lubrication. This situation can slightly increase the idle heat Travel time ranges from tens of seconds to 1 minute.
- Do not all EFI engines need in-situ hot cars?
Answer: Not all, but most. Although the overall process of the engine has been greatly improved, there are still some differences between the engines of different auto manufacturers. In fact, there are still a small number of auto manufacturers that require hot
cars. You can refer to the user manual of your model.
