Performance Optimization of Single Cylinder Diesel Engine Oil Pump through PRV and Rotor System 2015-26-0028

Oil pump is one of the important engine parasitic loads which takes up engine power through crankshaft to deliver oil flow rate according to engine demand to maintain required oil pressure. The proper functioning of oil pump along with optimum design parameters over various operating conditions is considered for required engine oil pressure. Pressure relief passage is also critical from design point of view as it maintains the required oil pressure in the engine. Optimal levels of oil pressure and flow are very important for satisfied performance and lubrication of various engine parts. Low oil pressure will lead to seizure of engine and high oil pressure leads to failure of oil filters, gasket sealing, etc. Optimization of pressure relief passage area along with other internal systems will also reduce the power consumed by the pump. Hence, the various oil pump critical design metrics are reviewed for single cylinder diesel engine to have optimal performance along with reduced power consumption without reduction in the oil pressure at the main oil gallery. This design was validated in the engine against the current and optimized design.
