ジンの燃料噴射装置。 An intermediate housing interposed between a pair of adjacent cylinders of a multi-cylinder rotary piston engine includes a working chamber during the intake stroke of one cylinder of the pair of cylinders and a working chamber at the beginning of the compression stroke of the other cylinder. In the rotary piston engine, airflow flows into each side housing of the pair of cylinders facing the intermediate housing from the working chamber at the beginning of the compression stroke to the working chamber during the intake stroke. 1. A fuel injection device for a rotary piston engine, characterized in that a fuel injection valve is provided that injects fuel against this airflow at a time when the fuel injection occurs.
