The core of the air filter may become dirty from various impurities. If this occurs, the
performance of the engine will decrease because the amount of air entering the combustion
chamber is incorrect. Also, because the amount of air is incorrect, the amount of fuel entering
also becomes incorrect leading to an overall incorrect air/fuel mixture. This will lead to poor
performance of the diesel engine. Always keep the air filter and air filter core clean.
