Abstract: From emissions, economy and resource reserves, this paper illustrates the advantages of gas resources relative to petroleum resources, highlights the feasibility that some of the engine converted into dual�fuel engine, and describes the limitation of dual�fuel engine technology. From the characteristic and economy point of view, it illustrates the advantages of liquefied natural gas (LNG) resource, and introduces a gas supply system of dual fuel engine .Taking Mercedes�Benz heavy trucks as example, it makes clear that the feasibility that diesel engine converted into dual�fuel engine, and give the signal acquisition method. Compared with the diesel engine, get the fuel substitution rate, economy and energy ratio of dual�fuel engine.
Key words: oil and natural gas energy; dual�fuel engine; gas supply system; economy of dual�fuel engine
