With the increasing concerns over the environmental protection and the shortage of crude oil supplying, much effort has been focused on the utilization of alternative fuels in engines.
Natural gas (NG) is one of the most promising available fuels for internal combustion engines (ICE). However, due to the slow burning velocity and the poor lean-burn capability of natural gas, engines fueled with this fuel suffer from some demerits. An effective method to compensate those deficiencies is to mix the natural gas with the fuel which possesses wide flammability limit and fast burning velocity. Hydrogen (H2) is thought to be the best gaseous candidate for this purpose. Throughout history, there have been many studies regarding NG enriched with hydrogen as a fuel in internal combustion engines.
The present work consists of a survey of research papers on utilization of NG-H2 mixtures in spark ignition engines. It focuses on the impact of NG enrichment with H2 on engine performance. The effect on combustion characteristics such as in-cylinder pressure and heat release rate (HRR) is also investigated.
