Abstract
An oil pan assembly having an oil pan and an intake pipe attached to a bottom of an engine block is provided. The oil pan assembly includes an inner plate mounted to the oil pan so as to be disposed between the oil pan and a bottom surface of the engine block. The inner plate is configured to slow the flow of oil to an intake pipe so as to provide additional time for entrained oil to de-areate.
Claims14
An oil pan assembly having an oil pan and an intake pipe attached to a bottom of an engine block, the oil pan having a floor, the oil pan assembly comprising:
- an inner plate mounted to the oil pan and disposed between the oil pan and the engine block, the inner plate having a first panel, the first panel having a top surface opposite a bottom surface, the first panel disposed on a first plane and is angled with respect to the floor of the oil pan, the first panel extends an entire length of the floor of the oil pan, a ramp contiguous to the first panel and disposed on a second plane angled with respect to the first plane, the first panel having a first peripheral edge opposite a second peripheral edge, a top wall extends outwardly from the second peripheral edge of the first panel, the second peripheral edge being lower than the first peripheral edge, wherein oil is pooled against the top wall slowing the flow of oil so as to allow the oil to aerate before reaching the intake pipe.
An engine assembly having an engine block, wherein the engine block is tilted, an oil pan assembly mounted to a bottom of the engine block, the oil pan assembly having an oil pan, an intake pipe and a pump, the oil pan having a floor, the floor disposed along a generally horizontal plane, the oil pan assembly configured to catch oil, direct the oil to the pump wherein the pump returns the oil to the engine block, the engine assembly comprising:
- an inner plate mounted to the oil pan and disposed between the oil pan and the engine block, the inner plate having a first panel, the first panel having a top surface opposite a bottom surface, the first panel disposed on a first plane, the first panel extends an entire length of the floor of the oil pan, the first plane angled with respect to the floor of the oil pan, the first panel having a first peripheral edge opposite a second peripheral edge, a ramp contiguous to a first surface and disposed on a second plane angled with respect to the first plane so as to direct oil to the intake pipe, a top wall extends outwardly from the second a peripheral edge of the first panel, the second peripheral edge being lower than the first peripheral edge, wherein oil is pooled against the top wall slowing the flow of oil from the peripheral edge of the first panel so as to allow the oil to aerate before reaching the intake pipe.
