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.

Fuel Economy & CO2 Reduction in IC Engines is the key driving factor for the Product performance & Customer satisfaction all around the world. The Stringent CO2 Limits calls for Engine Friction Reduction, Engine Downsizing & other Alternative measures. The challenges were to measure the component level Friction Contribution on the Engine & to select the critical contribution parameter & to optimize the same. Oil pump is one such important engine parasitic load which takes up engine power through crankshaft to deliver oil flow rate according to engine demand. The proper functioning of the Oil pump is considered with required engine Oil pressure along with optimum power consumption over various operating speed and temperature. Hence the various Oil pump critical design metrics are reviewed for two cylinder Multi-jet diesel engine to have optimal power consumption and without reduction the Oil pressure at the engine oil gallery.
