The invention relates to an engine crankcase, which belongs to the technical field of engines. The crankcase includes a crankcase body, a filtering device and a collecting device. The crankcase body is provided with an oil storage tank storing lubricating oil; the filter device includes a housing, a filter cavity and an oil pusher, and the housing is provided with a first oil inlet channel, an oil filter channel and a slag discharge channel, and the first oil inlet channel The oil filter channel and the oil filter channel are respectively connected with the oil storage tank, the oil pusher is set in the shell, and the filter element for separating oil liquid and oil residue is arranged in the oil filter channel; the collecting device is connected to the slag discharge channel position of the shell and opens and closes the slag discharge channel . The invention pushes the lubricating oil entering the first oil inlet channel to the oil filter channel for filtration through the oil pusher, and the filtered pure lubricating oil flows back into the oil storage tank from the oil filter channel, and the oil filtered out of the lubricating oil The slag continues to accumulate in the slag discharge channel under the push of the oil pusher, and the accumulated oil slag can be cleaned and collected only by periodically opening the collecting device.
Description
technical field [0001] The invention belongs to the technical field of engines, in particular to an automobile engine crankcase. Background technique [0002] The part of the lower part of the cylinder block used to install the crankshaft is called the crankcase. The crankcase is composed of an upper crankcase and a lower crankcase. The upper crankcase and the cylinder block are cast as one. The lower crankcase is used to store lubricating oil and seal the upper crankcase. , so it is also called the oil pan. The oil pan bears little force and is generally made of sheet metal stamping. Its shape depends on the overall layout of the engine and the capacity of the oil. There is an oil drain plug at the bottom of the oil pan. The oil drain screw plug is equipped with a permanent magnet to absorb metal shavings in the lubricating oil and reduce engine wear, and a liner is installed between the joint surfaces of the upper and lower crankcases to prevent the lubricating oil from le...
