ABSTRACT:
The invention relates to a dry sump type or semidry sump type lubricating system of an engine in which a lubricating method executes an operation while keeping an inner side of a crank chamber in a dry state. An oil drain port is formed in a bottom surface of each of individual crank chambers partitioned into the cylinders, and a scavenging oil pump is provided so as to suck out oil to an oil reservoir portion which is isolated from each of the individual crank chambers. An oil collecting chamber communicating with a suction portion of the scavenging oil pump is provided in a lower side of the bottom wall in the crank chamber, and the oil drain port is communicated with the oil collecting chamber.
