Abstract
Systems and methods for delivering oil to an engine are provided herein. According to one embodiment, the oil delivery system includes an oil supply, a feeder passage fluidically coupled to the oil supply and a cylinder head, the feeder passage coupled to a pump and a filter positioned downstream from the pump. The oil delivery system further includes a squirter passage in fluidic communication with a plurality of piston squirters and the feeder passage at a position between the pump and the filter. In this way, less-filtered oil is selectively routed through a cooling circuit to reduce engine warm-up time.
