Engine Fuel Injector: Technology Deep Dive
Â
1.Function
Core actuator in electronic fuel injection systems. Precisely meters, atomizes, and times high-pressure fuel delivery, governing combustion efficiency, power response, and emissions.
Â
2.Core Tech
Â
Microsecond Solenoid: Piezoelectric crystal/high-speed coil enables multi-pulse injection (pilot/main/post). Response time ≤0.1ms;
Â
Nano-Atomization: Laser-drilled micro-nozzles (80-150μm) produce ≤20μm droplets, improving air-fuel mixing by 40%;
Â
High-Pressure Endurance: Tungsten alloy seat + ceramic needle valve. Withstands 150-2500Bar, >500M cycles anti-cavitation;
Â
Thermal Management: Thermal-conductive housing + compensation algorithm. No coking from -40℃ to 150℃.
Â
3.Performance
Â
Fuel Economy: ±2% flow accuracy, 5-15% fuel reduction;
Â
Emission Control: 90% less PM2.5, meets China VI/Euro 6D;
Â
Power Boost: 15% low-speed torque increase, +8% full-load power;
Â
Reliability: IP67 rating, 100,000km endurance (ISO/TS 16949).
Â
4.Applications
Compatible with TGDI, CRDi, HEV/PHEV, and hydrogen engines. Supports SUS/USCAR interfaces. Biofuel/synthetic fuel ready.
Â
5.Value Proposition
