Exhaust Bismarck ND
The exhaust system is responsible for carrying exhaust gases away from the engine in your car. Many problems can arise if your exhaust system and muffler are not working properly, so read on to learn how to keep them in good shape.
Since most of the torque generated by the combustion process takes place by 90 after top dead center (TDC), the exhaust valve usually begins to open before bottom dead center on the power stroke. The residual combustion pressure in the cylinder is then released into the exhaust port, through the exhaust system, and into the atmosphere.
