Summary:

The Institute of Internal Combustion Engines and Thermodynamicsat Graz University of Technology has developed a low-pressure (5bar) direct injection (LPDI) combustion system for 50 cm₃two-stroke engines during the last years. The 50 cm₃ two-strokeengine is a specific European engine class. Worldwide the 125 cm₃class is more important. In order to investigate the potential ofhigher displacement engines equipped with the LPDI combustionprocess, a demonstrator engine with 250 cm₃ has been developed. Theresults of this demonstrator from the engine test bench and fromthe chassis dynamometer are discussed to show the potential of thistwo-stroke technology. In order to ease the interpretation, theresults of a homogenously scavenged two-stroke engine and of anaturally aspirated four-stroke engine serve as reference.The results show that the LPDI technology is a real alternativeto expensive four-stroke engines. The high efficiency and the verylow emissions are of special interest for the consumption-sensitiveIndian market, especially in high population urban areas with bigproblems due to high air pollution
