A diesel engine is one of the major prime movers owing to its high thermal efficiency. But due to the recent attention for the environmental pollution, the emissions of diesel engine became a important problem. So it is needed to understand the characteristics of diesel spray injected into a combustion chamber. Because the diesel combustion is strongly controlled by a fuel spray injected into a combustion chamber.<br/> <br/>

Generally. Vehicle owner's manuals recommend engine oil changes every 10,000km under moderate driving condition. although 5,000km is recommended under severe driving condition. However. most vehicle owners replace their engine oils within 5,000km driving. then this results in the waste of resource. In the present study. monitoring test of engine oil condition was performed to examine the degradation of oil property with 21 gasoline vehicles and 6 diesel vehicles. Major domestic engine oils were used in this test. and they were analyzed every 1,000km or 2,000km driving. Moreover. fuel economy tests were performed to clarify the effect of engine oil degradation on vehicle fule consumption.
