A gas tractor due to insufficient power to check and repair, the owner tells the failure of climbing weakness, flat road speed is much slower than before, by dismantling, bypass valve abrasion of turbocharger exhaust turbine end, resulting in Baotou North Benz accessories turbocharger speed boost pressure will reduce power shortage, natural vehicle worse, the basic gas engine is often the problem.

Here will have a card to ask why the gas engine is prone to this problem, it is necessary to start from the characteristics of gas engine, gas engine using natural gas as fuel, natural gas burning at 650 degrees, 220 degrees compared to diesel a lot higher, which leads to the gas engine operating temperature and high exhaust temperature.

On the other hand, in order to make the northern Baotou Benz spare parts engine have better low speed performance, the turbocharger exhaust exhaust volute is relatively small, so as to ensure the lower speed of the supercharger's normal work. When the engine speed increases, the exhaust pressure rises, the bypass valve opens to avoid the excessive intake pressure caused by the supercharger.

Two factors above, gas engine speed is relatively high and some diesel engine, the exhaust temperature is higher, more prone to high temperature exhaust gas exhaust pressure rise, this time the bypass valve supercharger action must be frequent, even close the throttle bypass valve will open. High temperature, high pressure, coupled with frequent opening, the seat of natural wear and tear intensified, a long time to produce a leak is not surprising.

However, there is no better preventive method for this problem at present. The only thing to do is to replace the North Baotou Benz spare parts, turbocharger volute or turbocharger assembly to solve the problem. Therefore, we should pay more attention to the use of gas vehicles, and if the power shortage is found, there is no problem checking other places, then there may be a problem here.
