Abstract

The fuel distribution in an air assist direct injection engine was measured with Planar Laser Induced Fluorescence, PLIF. The engine was fueled with isooctane and 3-pentanon was used as the fuel tracer. The optical engine was of the prolonged piston type, with a quartz ring in the upper part of the cylinder. Both the fuel injector and the spark plug were centrally located in the cylinder head. Two different pistons were examined: flat piston and bowl in piston. Results show that the differences in fuel stratification are very large for the flat piston compared to the piston with a bowl.
