Engines require a clean source of air for combustion and reliable operation. The failure of engine air induction systems can allow unfiltered air to enter the combustion chamber causing loss of performance, engine wear and severe engine damage due to the abrasive nature of particles commonly found in dust. The problem of unfiltered air entering an engine is known as ‘dust ingress’ or colloquially as ‘dusting’ and is a widespread problem across many sectors where engines routinely operate in severe environments. Dust ingress can rapidly lead to significant repair or replacement costs, machine downtime and loss of production. Dust ingress is often caused by damage to air ductwork, broken induction air hoses, broken or loose hose clamps and in some cases, failure of air filtration media.
