Key Performance Features

Feature	Benefit
Ultra-Precise Fuel Metering	Controlled by ECU and hydraulic actuation, injection quantity error < ±1%, ensuring optimal fuel-air mixing, improving combustion efficiency by up to 29%, reducing fuel consumption and harmful emissions (NOx & PM)
High-Pressure Atomization	6-hole 130μm nozzle with 650bar pressure delivers ultra-fine fuel droplets, enhancing combustion completeness, boosting engine power output, and meeting strict emission standards
Superior Wear & Corrosion Resistance	High-strength alloy steel with wear-resistant coating (HRC58-60) and precision-machined components extend service life in high-dust, high-humidity, and long-term high-load conditions
Zero-Leak Sealing	Factory-installed high-pressure metal wound gasket ensures reliable sealing under extreme pressure fluctuations, preventing fuel leakage and maintaining system stability
Direct-Fit Design	No modific-ations required, reducing installation time, labor costs, and equipment downtime for C9.3 engine maintenance
