| Abstract:A six cylinders gas engine was developed on the basis of traditional diesel engine design, and the gas intake of which requires pre-mixing before turbocharging. However, the traditional compressing starting system was not able to ensure the reliable start. Therefore, a new three cylinders starting system was developed. The mechanism, design, and improvements of designs were introduced. Experimental tests showed that improved starting systems could ensure the reliable start of gas engine. |
