2. 1. Alternative Combustion Strategies for Gasoline Engines

   Author : Daniel Dahl; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; engines; SI; SGDI; CAI; HCCI; Otto; lean burn; gasoline; combustion; fuel consumption;

   Abstract : Due to increasingly strict legislative demands and customer concerns regarding CO2emissions, there is a need to develop and implement new combustion strategies forgasoline (Otto) engines. In attempts to meet this need, most attention is focusing onthe low load/speed range where the classic spark ignition strategy (SI) has poorefficiency, mainly due to the throttling of the intake air causing pumping losses.
