A New Combustion System for 2-Stroke HSDI Diesel Engines 2007-01-1255

The Department of Mechanical and Civil Engineering (DIMeC) of the University of Modena and Reggio Emilia is developing a new type of small capacity HSDI 2-Stroke Diesel engine, featuring a specifically designed combustion system. The present paper is focused on the analysis of the combustion process, investigated by means of a customized version of the KIVA-3V code.
A four stroke automobile Diesel engine featuring a very close bore size is taken as a reference, for both the numerical models calibration and for a comparison with the 2-Stroke engine. Such a comparison clearly demonstrates the effectiveness of the two stroke concept in terms of emissions reduction and high power density.
