A comprehensive review on the utilization of hydrogen in low temperature combustion strategies: Combustion, performance and emission attributes
Abstract
The environment is polluted in such a way that, serious health risk started to appear in humans as well as other living things across the globe. It is a well-known fact that the major contributor to this situation is the transport sector and this made countries across the globe to implement stringent emission regulations for internal combustion engines (ICE) which in turn prompted researchers and industries to turn their focuses to alternative fuels and technologies. With a high calorific value of 120 MJ/kg and absence of carbon bond, hydrogen is reckoned as one of the most promising fuel which can help in curbing the emissions coming out from ICE. Many studies conducted over the years by introducing hydrogen into conventional combustion methods showed that apart from the knocking phenomena, one of the major drawbacks of hydrogen fuelled ICE is the NOx emission. This is where implementation of low temperature combustion (LTC) strategies becomes important. This recently developed combustion technology can help in reducing the NOx and soot emissions without affecting the performance of the engine. Integrating hydrogen fuel and LTC strategies seems to be promising, but there are several challenges that needs to be addressed before commercializing this technology. This paper has undergone extensive analysis of the existing studies on neat hydrogen as well as hydrogen addition in various LTC strategies; discussing the performance, combustion and emission attributes besides the present limitations of the technology and this could be used as a touchstone for future studies and commercializing the technology.
