HH465Q-1EA, a model of dual fuel engine which was developed independently by our company for the end users who are from countries rich of Nature Gas. It is based on the HH465Q-1E and add a electromagnetism snifting valve in each intake manifold, the Nature Gas would be reduced pressure by reducing valve, then the fuel amount would be controlled by electromagnetism snifting valve which would be controlled by original ECU with another special control Unit. This dual fuel engine almost was kept similar outside structure with HH465Q-1E but with higher economy which can meet GB.
