Operating a diesel engine with excessive exhaust backpressure can result in several specific types of damage. Excessive exhaust backpressure means that the exhaust gases are not able to exit the engine cylinders efficiently. First, it can cause burned exhaust valves. The increased pressure and temperature in the combustion chamber can overheat the exhaust valves, causing them to warp, crack, or burn. This prevents the valves from sealing properly, leading to compression loss and reduced engine power. Second, it can lead to increased cylinder temperatures and pressures. The increase....
