Abstract

This paper presents a computational method for the analysis of compression process using different heat transfer correlations for a 4 stroke LPG- Diesel dual fuel compression ignition engine and these results form the basic input for the combustion process. Variable heat exchange between the air+ gaseous fuel+ residual gas mixture and the cylinder wall during the compression process will affect the work requirement for the compression process as well as thermal load variation in the cylinder wall. A computer program was formulated in MATLAB 7.01 for compression cycle computation of index of compression, pressure, temperature, heat transfer and work required. Results show that average compression index for the compression process is 1.35 which is very close to the value suggested by Hardenberg & Hase. It has been observed that computed values of temperature and pressure match with the experimental values.
