Abstract: A two cycle internal combustion engine is disclosed, which essentially comprises a cylinder consisting of a sleeve and a cylinder block housing the sleeve therein. The cylinder has a groove formed between the sleeve and the cylinder block and at least one lubricant outlet port having one end opened to the inside of the sleeve and the other end communicating with the groove. A lubricant inlet port is formed in a crankcase or an air-fuel intake passage of the carburetor connected to the crankcase, and is connected to the groove through a lubricant passage means including a check valve disposed therein.
