experimental investigation of gasoline fueled hcci engine load expansion
operating an engine with homogeneous charge compression ignition (hcci) technique is a promising technique to lower nox and pm emissions of engines while achieving high efficiency and lower fuel consumption. nevertheless, applications for hcci are still limited due to the absence of a definite means to control ignition timing and narrow operating region. a single cylinder diesel engine with com...
متن کاملEvaluating the EGR-AFR Operating Range of a HCCI Engine
We present a computational tool to develop an exhaust gas recirculation (EGR) – air-fuel ratio (AFR) operating range for homogeneous charge compression ignition (HCCI) engines. A single cylinder Ricardo E-6 engine running in HCCI mode, with external EGR is simulated using an improved probability density function (PDF) based engine cycle model. For a base case, the incylinder temperature and unb...
