式エンジン。 A crankcase supercharging type in which the combustion chamber of the engine and the crankcase are connected through an intake passage, and as the piston reciprocates, intake air is sucked into the crankcase, pressurized, and sent under pressure to the combustion chamber. In an engine, a lubricating oil tank is formed separately from the crankcase, and the two are communicated with each other via a communicating oil passage, and the communicating oil passage is blocked by a counterweight provided on the crankshaft in a piston descending region. A crankcase supercharged engine characterized by being configured to allow
