Hangzhou longer industry Co.,Ltd specializes in producing CNG/LPG conversion kits and related hardware for multipoint sequential injection system of cars. Such as Volkswagen, Hyundai, Toyota, Chery, BYD, Ford, GM and more. As a leading player of this area in China, we have a professional R&D team and a laboratory for product testing.

Our CNG conversion kits including 4 models: EG100, EG500,EG700 and EG800.

System Characteristics:
1. The air-fuel ratio of engine of engine is controlled with closed loop, therefore the exhaust gas emission is low (Euro 3 and Euro 4); And keep engine be more powerful
2. Self-adaptive, self-diagnosis and self-learning function, No interference with the OBD system of the vehicle
3. ECU set is suitable for both of LPG & CNG conversions, Optimized Varying Climate Conditions
4. sequential gas injection system working in real time, assures optimum gas into each cylinder
5. cooperation with lots of gas injectors well, adjusts opening time of each injector on the rail, Testing of the injectors enabling to diagnose the faulty injectors
6. Takes signals in Real Time in all operating conditions to obtain optimum opening time of each injector.
a) i.e. gas / water temperatures, manifold depression, rpm, petrol injection.
7. High Reliability & Adaptability and User Friendly
8. Easy Software Installation (Fully Windows Based)-Mapping & Calibration
9. No Need of OMD Emulators
10. Designed for ultra low emission
11. Save to ECU/Load from ECU/Save to File/Load from File is all possible
12. Pressure Sensor: Automatic switch to the gas when the gas is run out
13. No need cutting off the wires thanks to sockets placed inside the injection connectors
14. Diagnostic strategies are in force to enable automatic switching to gasoline mode should the system detect a fault, Auto fault clearance
15. It manages full group motorisations, semi-sequential and sequential slave in one single card.
16. Integrated Powerfully Microprocessors, Wate
