The harm of in situ hot car

The harm of in situ hot car

  1. waste oil;

  2. carbon build-up;

  3. pollute;

Driving car slowly is hot car way.


Although the EFI engine is not sensitive to temperature, but the lubrication system is still relatively sensitive, low temperature, high oil viscosity, poor flowability, lubricating ability, mechanical wear between components than under normal conditions to be serious. So don't suggest cold high speed driving, should follow the "low turn slow" principle, gentle normal driving, avoid big throttle.

   



Maintenance technician says so

In situ hot will really destroy a car? This reporter interviewed SAIC Volkswagen, Guangzhou TOYOTA and the Yangtze River, the responsible person.

"I think that in the cold weather, there is still very necessary." Jac customer service director Zhu Dongkun said, the reason is hot, after a long time the car parked in the engine, oil engine oil flows back into the lower part of the bottom shell. After the ignition, the engine of the upper part is not in lack of lubrication oil, to about 10 seconds after launch, due to oil pump operation and will be delivered to the engine oil lubrication of the piston, the connecting rod and crankshaft and other parts. Moreover, low temperature, easy oil solidification, if not hot hot, to the point of time for liquefied oil, but directly away, easy to wear and tear caused by the engine.

SAIC Volkswagen tianshuncheng customer service director Shi Dianxin also said that in the situation of low temperature, oil viscosity, in situ hot can make oil lubrication, reduce wear of the engine, so it is necessary to.

Of course, there are different views. Technical staff of Guangzhou TOYOTA said that with the application of automobile electronic fuel injection technology in engine, the car has become increasing engine wear, increased engine coke, increase fuel consumption of the culprit. That is to say, the EFI car completely unnecessary in situ hot.
