Experimental Study on Performance of P-HCCI Engine using Biodiesel Mixture

This paper represents the performance of single cylinder HCCI Engine using Biodiesel Mixture. The Homogeneous charge compression ignition (HCCI) combustion is a new trend alternative technology to current engine combustion systems. Many inventions in PHCCI is being worked out to use it as a method to reduce exhaust emissions and also fuel economy. The quality of homogeneous mixture of air and fuel is the key feature of HCCI combustion. HCCI has the characteristic 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 NOx and PM emissions. The purpose of this study is to analyze the effect of alternative fuel when used in the HCCI engine combustion process. The experiments were conducted in a modified single cylinder water-cooled diesel engine. In this experiment we use diesel and bio-diesel Mixture as the fuel at different milli second injection.
