— A control strategy designed to track desired combustion phasing for a homogeneous charge compression ignition (HCCI) engine during large load transitions is presented in this work. Three inputs are controlled, namely valve timings, fuel injection amount and fuel injection timing. The valve and fuel injection timings are manipulated to track combustion(More)
— The fuel governor control design methodology presented in [1] is extended and experimentally validated on a multicylinder recompression homogeneous charge compression ignition (HCCI) engine. This strategy regulates desired combustion phasing during load transitions across the HCCI load range. A baseline controller tracks combustion phasing by manipulating(More)
— Reduction of combustion phasing cyclic variability (CV) in homogeneous charge compression ignition (HCCI) engines operating lean with late autoignition is experimentally demonstrated. A three–state discrete time model developed in [1] is used for controlling the fuel injection timing and is applied to a multicylinder engine. A key objective of this work(More)
—The cyclic variability (CV) at late phasing conditions in autoignition engines with high residuals limits the operating range of such advanced combustion strategies. A model has been recently proposed by the authors that captures the experimental observations of CV in lean autoignition combustion in a single-cylinder engine. The model is here tuned to(More)
