closed crankcase The crankshaft is thesame general type as a gasoline engine and the diesel enginehas the same type of valves camshaft pistons connectingrods and lubricating to a great extent a diesel engine requires the samepreventive maintenance as a gasoline engine The mostimportant factors are proper ventilation and proper mamtenance of the fuel lubricating and cooling systems Fuel andlubricating filter elements must be replaced at the time periods specified and frequent checking for contaminants watersediment etc in the fuel system is also essential factor is the consistent use of the same brand ofhigh detergent diesel lubrication oil designed specifically fordiesel enginesThe diesel engine does differ from the gasoline enginehowever in its method of handling and firing of
