Apparatus for direct gasoline injection in a piston engine

摘要

The invention relates to an apparatus for direct gasoline injection in a piston engine, which has a hydraulic valve control system with hydraulically actuated gas exchange valves. The invention proposes binding the direct gasoline injection to the hydraulic valve control system via a pressure booster for two different pressure media, which is acted upon by hydraulic oil from a high-pressure hydraulic oil reservoir of the hydraulic valve control system and which subjects a high-pressure fuel reservoir to high pressure; injection valves for direct gasoline injection in the piston engine are connected to the high-pressure fuel reservoir.
