An Experimental and Numerical Investigation of the Combustion Characteristics of a Dual Fuel Engine with a Swirl Chamber 2007-01-0615

In order to pursue further improvements to the performance and emissions of small size dual fuel engines with a swirl chamber, a 3KC1 ISUZU engine setup was rebuilt, and a 3D-CFD model based on KIVA was developed. The simulation incorporates a reduced detailed chemical kinetics for the diesel fuel but with detailed chemical kinetics for the gaseous fuel component, mainly methane while considering the turbulence function to simulate the combustion processes and associated performance of a dual fuel engine with a swirl chamber. The effects of changes in the quantities of the liquid fuel pilot and gaseous fuels on the combustion processes, engine performance, cyclic variations, and emissions were investigated both experimentally and numerically.
