ABSTRACT:
A two-stroke internal combustion engine of the crankcase scavenging type, in which a nozzle connected to a lubricant feed line is provided in the intake passage for picking up oil from a lubricant reservoir via a partial vacuum. For simple and sufficient lubrication and cooling of the crank gear in accordance with the respective requirements of the engine, the nozzle (62) is positioned in the area of the smallest cross-section of a Venturi-tube-like part (60) of the intake passage, and an injection pump (54) is provided for fuel delivery, which eliminates the need for an oil pump.
