Start-up Eco-Motive developing dual-fuel “H” engine; parallel, independently fueled piston banks

Green Car Congress

The H-engine—basically two separate engines housed within the same engine block—comprises two switchable parallel piston banks, independently fueled by gasoline and CNG. Startup Eco-Motive has developed what it calls the first dual-fuel “H” engine; it recently received a patent (# 8807098 ) on the design.
