Abstract
Map-controlled variable displacement oil pump (VDOP) and map-controlled piston cooling jets (PCJ) are two kinds of technologies to reduce the fuel consumption. In order to assess the fuel consumption contribution due to the two technologies, a lubrication circuit CAE models have been built up and three steps were done. First to confirm the maximum displacement of VDOP, and then to determine the oil pressure control strategy of map-controlled VDOP. And final fuel consumption contribution of two technologies is simulated according to the oil pressure control strategy. It is showed that the hydraulic power saving on certain condition which the engine often work at is up to 73–85% at low speeds, and it saves 20% when high speeds with high loads.
