Hydrogen As Dual Alternate Fuel for the Diesel Engine Using EGR Technique
Internal combustions engines use petroleum products as a fuel for its running. Due to industrialization and expansion the consumption has increased at a very high rate. If this trend would follow it can lead to shortage in near future and may even exhaustion of petroleum reserves. Thus, there is a need for sustainable use of the petroleum products.
Apart from the high efficiency it also produces low emission levels of CO2, low CO and HC exhaust levels. Despite all these advantages, diesel engines emit high NOx and particulate emissions, which causes adverse health and environmental problems like acid rain, smog. With the stringent emission norms introduced by the government and environment and health impacts there is a serious need to search for alternatives.
Hydrogen being the clean fuel and having high caloric value is a good option to be used in industries for power. But it is not available much in free state as most of it is in form of water. Hydrogen, being the potential fuel for the future we try to investigate using the hydrogen as dual fuel for the diesel engine. Using hydrogen can increase the temperature of operation and increase Nitrogen oxides. In order to avoid the detonation problem we are using Exhaust Gas Recirculation Technique and will look how emissions will be affected.
