Our Gaseous Small Engine EFI kit is a conversion kit for some 1 or 2-cylinder carbureted small engines. This kit can convert the carbureted gasoline engines to gaseous fuel injected engines. It's kind of one-stone, two birds. Not only you can switch to alternative gaseours fuel, like CNG, LPG, Hydrogen, BioGas, etc;
but also it is fuel injected. Further more it can be configured as dual-fuel injection system, meaning you can run on both gasoline and gaseous fuel.
For example, you can start the engine with gasoline, and after warmed up, switch to CNG (simply a flip of the switch).
This technology has been done with big car engines. Now it's made available for small engines. Same as our gasoline fuel injection kits, the system is fully tunable.
As gasoline becomes more expensive, and alternative fuels become more attractive, this kit turns the potential into reality.
Video: A Honda GX390 engine has been converted to a Hydrogen fuel-injected engine with an Ecotrons EFI kit! For the first time, the hydrogen is made as a viable alternative fuel for portable power generators!
This EFI kit has below features:
Electronic fuel injection (EFI)
ECU controlled ignition system (CDI or inductive coil)
fully tunalbe, better use our ALM to tune, running with 1.5 to 2.0 lambda
Dual fuel swtich-able by a manual switch (use gasoline for cold start and warm up, then switch to gaseous fuel)
High fuel efficiency and low carbon emissions
On board self-diagnosis with a MIL lamp
Advance tuning for OEM customers
2.Harness (including the connectors)
24mm/28mm/34mm/42mmm Throttle body (including TPS sensor)
Gaseous injector (2mm/3mm/4mm diameter); and fuel injector (38/60/80/128/190/240g/min)
4.MAP sensor (1.05bar)
5.Engine temperature sensor
6.Intake air temperature sensor
7.CDI - for ECU controlled spark advance (Optional, suggest to add, for better controls)
8.Oxygen sensor and bungs (optional, suggest to add, to have close-loop fuel and self-tuning features)
9.Serial communication cable (to a computer)
10.Serial to USB converter (optional, NOT included)
11.CD - free tuning software (also downloadable)
This kit needs tuning for different fuels. Tuning instructions are availabe as downloadable documents. Tuning software is free for trials.
