This should be a lot of card will encounter problems, specifically ask some old driver, some drivers think so since the exhaust brake design, it is certainly not a problem, because the negative pressure generated by the engine working stroke is much higher than that of the exhaust brake.

Also, the old driver believes that the exhaust brake blocks the normal exhaust exhaust, the high pressure easily "bad" exhaust manifold pad, in the actual use of the process, there will be such a thing.

Improper handling is the cause of an acute card problem

So why is there such a problem? Mainly because many card is "acute", when the vehicle is traveling to the top of the hill, the engine temperature is relatively high, the exhaust gas temperature is also high, resulting in transmission to the exhaust pipe and other components of the temperature is very high.

A card impatient at the beginning of the downhill using the exhaust brake, but due to the higher temperature, the exhaust manifold pad is easy to be burnt, and this is what we usually are washed out of the exhaust manifold exhaust brake.

Correct posture can be solved, first hang against the brake

Many people encounter this problem, always complain about the Baotou north, heavy truck parts, engines, radiators and other quality is not good, but did not reflect on their own operation is correct. This can be avoided if proper operation is used on the downhill.

In the downhill right way should be the first to hang low gear to use the brakes, to the normal operation of the engine (the injection or spray a small amount of oil), away because of a large number of heat generated by high load running uphill, and then using the exhaust brake.

When the engine speed is high, the exhaust brake is opened, and the instantaneous pressure is too large, which is one of the reasons that caused the exhaust manifold cushion of Baotou North Heavy Duty Truck parts. So we can in Baotou beiben heavy duty truck accessories when the engine speed low open exhaust brake switch (1500 rpm or less), let it slowly increased, so the exhaust manifold pressure is gradually increased, the exhaust manifold gasket damage will not be too big.

Good driving habits, can effectively improve operational efficiency. A little attention driving method may lead to problems in the vehicle, we usually drive, or to pay more attention to the driving style, insist on a period of time, you will find your "old man" may not have a problem before then love
