Hydrogen and diesel combustion

The important motivations for exploring alternative fuel resources are energy security and air pollution, problems that are collectively calling into question the fundamental sustainability of the current energy system.Hydrogen-fuelled engines with near-zero emissions are a potential near-term option and a bridge to hydrogen fuel cell vehicles.With emission legislations getting more stringent,research studies have definitely established the advantages of extremely clean burning characteristics of hydrogen as a dual fuel in engines.But that said,the premium of using hydrogen as a green energy carrier needs to be augmented with studies on its potential to satisfy conventional engine combustion characteristics for ready deployment.In this present study, the performance and combustion analysis were carried out on an existing direct injection diesel engine at various load steppings using hydrogen inducted at different injection timings and injection durations.The findings of the study cater to its audience interested to employ such uses in practical diesel engines and also to those chartering a course of pursuance in the context of reducing emission from existing combustion engines.
