Study on Combustion Characteristics of Gas Engine using Waste Origin Low Calorie Gas

Abstract

It is necessary to develop the high efficiency gas engine which uses waste origin low calorie gas for effective use of energy resources. For example, the composition of the waste origin low calorie gas is composed of H_2CO.CO_2 of 30∿35vol% each other. The low calorific value is about 7.5MJ/m^3_N which is equivalent to 1/5 of city gas. Authors have studied the combustion characteristics and practical tuning method of the pilot ignition gas engine.
