Hydrogen Combustion in I.C Engines

Abstract

The use of hydrogen as a fuel for the internal combustion engine represents an alternative to solve both of the greatest problems related to the use of classic fuels: the limitation of the fossil fuels consumption and the environment pollution. We first describe hydrogen-engine fundamentals by examining the engine-specific properties of hydrogen and topics that are discussed include abnormal combustion (backfire, pre-ignition and knock),emissions of NOx and load control strategies (power output versus NOx tradeoff). Finally, we consider comprehensive overview of the design features of a dedicated hydrogen S.I., Direct-Injection hydrogen fueled internal combustion engine.
