2. Operation and Management Inspection and Repair of the Engine Checking Engine Parts after Prolonged Operation Intake Unit Be careful when handling the air filter in the intake Wear, corrosion, or degradation of engine elements unit. If oil level of the wet air filter is below the and assemblies may occur, causing lowered specified level, filtering performance is degraded. On performance of engine parts. To maintain high engine performance, check the engine after prolonged the other hand, if the oil level is higher, oil may flow into the case, and it may become polluted. In regards operation to enhance the durability of the engine.
to the dry air filter, intake resistance should be small Unexpected faults may occur in some weak engine to ensure the smooth intake of air. parts after normal operation of the engine, when operation time is prolonged. In this case, it is difficult Exhaust Unit to maintain high engine performance by simply If exhaust emission is leaked from the part connecting repairing some parts. We recommend the entire part be replaced or repaired in order to find out the the exhaust tube and the turbocharger, the causes more accurately and maintain high engine supercharger efficiency is lowered, causing degraded engine output and, if serious, burning of related parts. performance.
As parts related to exhaust and turbocharger are To prevent engine failure in advance and use the engine safely for a long period, perform periodic used at high temperature, be careful not to mix the bolts and nuts with other parts when performing replacements and inspections. repair. It is recommended to perform engine adjustments and preventive inspections during spring after the engine was exposed to winter or cold weather. This allows Lubrication Unit economic, long-term use of the engine without faults. As the following parts affect the engine output and Inspection and exchange of oil and oil filter should be performed while considering their exchange cycle.
performance, these parts should be regularly checked Overheated engine oil significantly affects the engine and inspected. performance as well as the engine performance, as 1. Parts affecting intake and exhaust well as the engine itself. Air filter Intercooler Supercharger, silencer EGR cooler and Calve Other parts 2. Parts affecting lubrication and cooling Air filter Oil filter Antifreeze Other parts Inspection and Repair of Supercharger As performance of supercharger significantly affects the engine performance, regular inspections and repairs should be performed and inspection and maintenance regulations should be observed. 2 - 7
