In the development of automotive engines, reduction of fuel economy is one of very important issues. We focused on reduction in oil pump friction which accounts for 10% of engine friction to enhance fuel economy. As a result, oil pressure was reduced at excessive areas by variable discharge by maintaining required oil pressure for the engine. By that we have succeeded in developing a variable discharge oil pump which can reduce friction by 33% at frequently-used engine speed range.
