PRODUCT CENTER
EFI System
Zhengyao EFI Electronic Fuel Injection System is designed for aviation two-stroke engines. Based on real-time engine operating-state sensing and intelligent ECU control, it continuously optimizes fuel injection and ignition characteristics to improve the EFI system’s adaptability to engine variation and enhance power stability. The system enables precise combustion control, reduces fuel consumption, and suppresses thrust fluctuations. It also monitors engine health in real time and diagnoses fault information, while supporting CAN/RS232 data transmission and system integration. The system is currently compatible with multiple engine displacements, including 120 cc, 170 cc, and 222 cc, and can be customized for specific electronic fuel injection system development requirements.
