Investigations on Reduction of Power Consumption of Oil Pump for New Advanced Multijet Diesel Engine 2009-01-1463

Automobile OEM's around the world are looking to improve their overall vehicle and engine efficiency in terms of fuel economy and power output. Efficiency improvement is possible by cutting down the engine parasitic loads. Lubrication oil pump is one such source for parasitic loss of multijet diesel engine. One best way of reducing the same is by optimizing the power consumed by the oil pump without appreciably affecting the flow requirements of the engine. This paper describes an effective approach to bring down the power consumption of a fixed displacement oil pump by keying out various factors contributing for the same. Detailed here are the methods used for identifying those factors, modifications carried out in the design, and testing methods employed for the estimation, together with the results achieved. The test results show that it is possible to improve the power consumption of oil pump by 18% as a result of this study. The design modifications were also validated for the life of the product, followed by checking the performance and wear of moving parts.
