The variations of lower heating value, theoretical air fuel ratio and combustionpotential of natural gas fuel were investigated according to the variation of natural gas composition in China.
The potential for increasing engine efficiency is substantial and even greater when coupled with advances in internal combustion engines.
这种引擎的效率还有很大的提升潜力，如果与内燃机配合使用其综合提升潜力将会更大。
