The pressure-assisted design is more resistant to damage from fuel-borne debris than a pressure-balanced system. To avoid a backflow of heated fuel and requiring a fuel-cooling system, Cummins fuel injectors have pressurized spring cavities which ensures minimal to no leakage and eliminates the need for additional cooling and improves overall fuel economy.
Cummins offer a system complete with leakless injectors, enabling a robust and durable product.
Injectors tailored to match duty cycles and provide industry leading fuel economy, delivering and delivers up to 5% efficiency improvements over our competitors.
Leakless injectors contribute to more than 25% reduction in fuel system parasitic power consumption over typical mid-range injectors for overall engine fuel economy improvement.
