Alternative Fuel Injector

Enabling clean propulsion through engine innovation

BENEFITS

Amplia gama de aplicaciones

Diseño flexible

Rendimiento eficiente

Stanadyne’s multipurpose low-pressure port fuel injector is capable of high-flow rates and has flexible packaging for a variety of port fuel injection applications. The higher flow capacity and scalable flow capability provide superior fuel-air mixing features of the new injector permit equivalent energy density fuel delivery when compared to traditional hydrocarbon fuels. Its modular design is based on improved materials for robust hydrogen, compressed natural gas, and DME compatibility.
