摘要

Lubricating oil supply system for rotary piston engine with a fuel injection valve fitted within the engine inlet channel to inject the fuel at high speed. A lubricating oil nozzle is located down flow of the fuel jets coming from the injection valve to lubricate one rotary cylinder of the engine. The open end of the lubricating oil nozzle is located to ensure that it is always subjected to the fuel jets, and the fuel injection valve and the lubricating oil nozzle are positioned to ensure that the oil injection cuts the fuel injection at an acute angle.
