Experimental Investigation on Hydrous Methanol Fueled HCCI Engine Using Spark Assisted Method

The present work investigates the performance and emission characteristics of hydrous methanol fuelled Homogeneous Charge Compression Ignition (HCCI) engine. In the present work a regular diesel engine has been modified to work as HCCI engine. Hydrous methanol is used with 15% water content in this HCCI engine and its performance and emission behavior is documented. A spark plug is used for ass...

Numerical Investigation of the Effect of Cooled EGR on Turbocharger HCCI Engine Performance Fueled with Methane

The three-stage auto-ignition of gasoline in an HCCI engine: an experimental and chemical kinetic modelling investigation

The alternative HCCI combustion mode presents a possible means for decreasing the pollution with respect to the conventional gasoline or diesel engines, while maintaining the efficiency of a diesel engine or even increasing it. This paper investigates the possibility of using gasoline in an HCCI engine and analyses the auto-ignition of gasoline in such an engine. The compression ratio that has ...

An Experimental Investigation of Combustion, Emissions and Performance of a Diesel Fuelled HCCI Engine

Homogeneous charge compression ignition (HCCI) is an advanced combustion concept that is developed as an alternative to diesel engines with higher thermal efficiency along with ultralow NOx and PM emissions. To study the performance of this novel technique, experiments were performed in a two cylinder engine, in which one cylinder is modified to operate in HCCI mode while other cylinder operate...
