Experimental investigation on effect of EGR on biofuel fueled HCCI engine using external fuel vaporizer- A Technical review
The Homogeneous charge compression ignition (HCCI) combustion is an alternative to current engine combustion systems. The research in HCCI is being carried out to use it as a method to reduce emissions and also enhance engine efficiency. HCCI has the potential to nearly eliminate NOx emissions while increasing efficiency as in diesel engine. HCCI adapts a pre mixture of gas-phase fuel and air being burned spontaneously and entirely by an auto ignition process. Homogeneous Charge Compression Ignition (HCCI) engines promises a high thermal efficiency combined with low levels of nitrogen oxides and particulate matter emissions. The purpose of this study is to summarise the effect of alternative fuel when used in the HCCI engine combustion process. Modification of single cylinder diesel engine runs on HCCI mode with diesel and biofuel. Installation of EGR system on HCCI engine. To study the effect of EGR rate on the engine exhaust parameter like nitrogen oxides (NOX), carbon oxides (CO and CO2), particulate matters (PM) and unburnt hydro carbons (UHC) by running the engine on HCCI mode with biofuel.
