ABSTRACT:
A magnesium oil pan prevents noise and vibration by attaching reinforcement members to portions that are weak in strength and are vulnerable to vibration. The magnesium oil pan includes a flange formed on an upper surface of the oil pan so as to be coupled with the cylinder block, a lower oil pan coupler formed on a lower surface of the oil pan so as to protrude downwards, and a bracket formed on a lateral surface of the oil pan so as to be coupled with a chain cover of the engine. The lower oil pan coupler includes a main reinforcement rib on an inner side of the oil pan which continuously runs between opposite inner walls of the lower oil pan coupler and protrudes downwards. Thus, the magnesium oil pan is made lightweight, improves noise-proof performance, and is hardly damaged by external impacts.
