Progress in FORESIGHT Homogeneous Autoignition Engines

A major outstanding issue for HCCI engines remains the limited window of operation, outside of which requires the engine to return to conventional SI operation. This limits the gains achievable with respect to improvement in fuel consumption and reduction in NOx emissions at vehicle level. The UK Foresight Vehicle program is sponsoring a 3-year research project named CHASE (Controlled Homogeneous Autoignition Supercharged Engine) exploring the combination of boosting, new aftertreatment and fuel reforming with total thermal management in order to expand the HCCI window. This paper reports the progress of the project in its first year. It is shown that while proposed software and hardware are still under development, preliminary single-cylinder engine tests have demonstrated strong effects from boosting and internal EGR rate on the upper load boundary.
