The HDEV 5.2 is a high-pressure fuel injector designed for use as either a port or direct injector.
Its primary function is to precisely meter fuel delivery while ensuring a consistent and well-defined fuel-air mixture.
This inward-opening solenoid injector has been engineered for exceptionally short opening and closing times, delivering stable linear performance even during brief injection cycles.
A key advantage of the HDEV 5.2 is its high spray adaptability — offering a wide range of spray angles, spray patterns, and flow rates. Bosch can tailor the spray targeting design to meet specific customer requirements.
If your application does not align with the listed performance specifications, Bosch Motorsport offers expert consultation. Alongside custom-designed solutions, Bosch can also supply cost-effective production versions of the HDEV 5.2 on request.
