    摘要： Embodiments of an oil pump for an engine have an increased pump capacity while maintaining or marginally increasing the overall physical size of the pump. In some embodiments, this increased capacity is reflected in a pump length efficiency ratio, which compares an effective gear length (LG) of first and second pump gears used in the oil pump, to an effective housing length (LH). The effective housing length (LH) is a longitudinal distance between surfaces on opposite ends of the oil pump that must be maintained for the oil pump to fit into an available space. Accordingly, the pump length efficiency ratio indicates how much of the effective housing length (LH) can be occupied by the gears. Alternatively, the pump capacity is measured using an output flow efficiency ratio, which compares a theoretical pump flow (FP) at a given gear speed (SG) to the effective housing length (LH) of the pump.
