“…In , it was demonstrated that there were three qualitative types of temperature dynamics of exhaust recompression HCCI across a wide range of ignition phasing points: smooth decaying for early ignition phasing, oscillatory for late ignition phasing, and strongly converging for moderate phasing. Analysis of the cycle‐to‐cycle dynamics in HCCI engines with varying amounts of exhuast gases in the cylinder demonstrated the same characteristics.…”

Homogeneous charge compression ignition (HCCI) holds promise for reduced emissions and increased efficiency compared to conventional internal combustion engines. As HCCI lacks direct actuation over the combustion phasing, much work has been devoted to designing controllers capable of set-point tracking and disturbance rejection. This paper presents results on model predictive control (MPC) of the combustion phasing in an HCCI engine based on a hybrid model formulation composed of several linearizations of a physics-based nonlinear model. The explicit representation of the MPC was implemented experimentally and the performance during set point changes was compared to that of a switched state feedback controller. The hybrid MPC produced smoother transients without overshoot when the set point change traversed several linearizations.

“…The development of the HCCI engine controller was studied with a stability analysis by Kang et al In this study, operating set points, such as the EGR rate, the airefuel ratio etc., were determined by a breathing process model and a combustion model [19,20]. The engine controller was then designed to follow those set-points in the HCCI combustion mode.…”

“…The engines operate in HCCI mode within certain power ranges and switch into SI mode when the engine speed and load increase to a certain threshold. In HCCI mode, an engine controller adjusts multiple actuators to maintain optimal combustion timing or crank angle position at 50% complete combustion (CA50) [2]. GM engines feature variable valve lift and phasing and a central direct-injection fuel system.…”

After initial trials on Homogeneous Charge Compression Ignition (HCCI) engine design and tests pursuing feedback control to avoid misfire and knocking over wide transient operation ranges, Engineers at the US Environmental Protection Agency's (EPA) National Vehicle Fuel and Emissions Laboratory identified the crucial engine state variable, MRPR (Maximum Rate of Pressure Rise) and successfully controlled a 1.9L HCCI engine in pure HCCI mode [1]. This engine was used to power a hybrid Ford F-150 truck which successfully ran FTP75 tests in 2004. In subsequent research, efforts have been focused on practical issues such as improving transient rate, system simplification for controllability and packaging, application of production grade in-cylinder pressure sensors, cold start, idling and calibration for ambient conditions as well as oxidation catalyst applications for better turbine efficiency and HC and CO emissions control. A 6.4L V8 HCCI engine and control system was then developed for a hydraulic hybrid shuttle bus as a demonstration platform. The bus has been tested in the laboratory against various driving cycles and driven on city streets, country roads and highways.This paper summarizes the system approach in developing the HCCI engine and its application on the hydraulic hybrid bus.
