ABSTRACT:
Two embodiments of lubricating systems for two-cycle internal combustion engines wherein a fuel/lubricant mixture is provided from a carburetor directly to certain components of the engine to be lubricated such as the rod bearings. This separate lubricant passage receives a fuel/lubricant/air mixture and is independent of the main intake passage of the engine. In one embodiment, a separate fuel/lubricant inlet extends into the carburetor downstream of the main induction nozzle. In the other embodiment, this separate lubricant passage has its own induction passage and own fuel/lubricant discharge nozzle.
