In order to solve the increasingly serious energy crisis and environmental pollution problems, we develop a electronically controlled dual-fuel engine natural for natural gas and diesel fuel. It is Modified by a electronically controlled engine, and work by diesel igniting the natural gas. We only add a natural gas supply system on the diesel engine, and give some appropriate changes in the fuel supply strategy, but the diesel engines emissions significantly improved.
We develop this electronically controlled dual-fuel engine on the basis of the YC6108 Diesel Engine. We make full use of the electronic control system on the diesel engine and precisely control the diesel and natural gas supply to improve the engine of the economy and emissions. On the one hand, we analyze fuel supply strategy, and design the gas supply system; On the other hand, we focused on the design of the gas supply system for some major installations, such as: the cylinder, the cylinder valve, filling gas Valves, gas pressure regulator, heating regulator, etc. We also design the gas supply system layout and installation under the bus frame.
