Supply of ventilation air to either the engine room or diesel engine directly affects
engine performances. Main criteria is supply of air volume and pressure into the
cylinder. When Air starts to come until the cylinders, there many points which
behave as restrictions. These are ventilation grills. ventilation fans, ventilation casings,
misteliminators, manual or pneumatically adjusted fan dampers, number of bending
of ventilation casing, cleanness of casings, air flow speed, air filters, turbocharger filter
and silencers, engine’s scavenge air cooler restrictions. Here, we focused on optimum
required air need through turbocharger for local diesel engine. While researching
actual need, new turbocharger filter were designed and manufactured for engine
manufacturer.
