The first domestic LNG-diesel vehicle successfully developed

This paper expounds the overall design proposal of LNG\|diesel vehicle. Under the preconditions of keeping the original structure and diesel combustion mode unchanged, a set of LNG gas supply system and LNG\|diesel dual fuel electric control injection system is added. The engine can work with dual fuel or full diesel. The system of dual fuel is controlled by electronic switch. The project is successfully developed; the substitution rate of LNG is as high as 84%, it is environment friendly and has prominent economic benefit.
