Abstract: A method to dynamically determine a parametric value for combustion chamber deposits (CCD), e.g. in a controlled auto-ignition engine, including in-situ evaluation of thickness of CCD, based on a sensor which monitors combustion in a homogeneous charge compression ignition engine. It includes a temperature sensor operative to monitor the combustion chamber, and a CCD parameter that is based upon a peak combustion temperature measured at a crank angle. A CCD parameter can also be determined utilizing an in-cylinder pressure monitor, wherein a combustion chamber deposit parameter is based upon crank angle location of a peak in-cylinder pressure parameter.

Abstract: A direct injection controlled auto-ignition engine is operated at steady state, within a homogeneous charge compression-ignition (HCCI) load range and with fuel-air-diluent mixtures at predetermined conditions, for each speed and load, of engine control inputs, including at least injection timing (FI), spark timing (SI), throttle position, exhaust gas recirculation (EGR) valve setting and exhaust recompression obtained by negative valve overlap (NVO). During engine speed transients, the control inputs are synchronized to changes in the current engine speed, and also with any concurrent changes in the engine fueling rate. Inputs that are inactive during all or part of a speed change have a zero change rate while inactive. The method maintains robust auto-ignition combustion during speed transients with constant or variable fueling rates and with or without load changes.

Abstract: A method is disclosed for expanding the mid load operation limit in a four-stroke gasoline direct-injection controlled auto-ignition combustion engine. A system is employed for variably actuating the intake and exhaust valves and for operating the valves with an exhaust re-compression or exhaust re-breathing valve strategy. A spark plug is provided. A fuel injector having multiple injection capability is employed. A first fuel charge is injected into the combustion chamber to form a lean air-fuel mixture. A second fuel charge is injected into the combustion chamber to form a stratified air-fuel mixture having an ignitable mixture located near the spark plug. The ignitable mixture is ignited at the spark gap, thereby causing spark-ignition combustion that causes a sufficient increase in chamber pressure and temperature to trigger auto-ignition of the lean air-fuel mixture, resulting in the obtaining of a higher engine load before a pressure rise rate in the combustion chamber exceeds a prescribed threshold value.

Abstract: The invention is directed to a continuous belt edge detector system for use in a paper making machine having a continuous belt guide device. The edge detector system comprises a continuous belt having an edge dope with metallic particles therein and an inductive sensor connected to the guide device and adjacent the edge dope. The inductive sensor sends a signal to the guide device indicative of a location of the continuous belt. The guide device moves the continuous belt, e.g., transversely relative to the running direction of the belt within the machine, dependent on the inductive sensor signal.

Abstract: Operation of a homogeneous charge compression ignition engine is adapted to fuel variations. A variable valve actuating system is employed to effect conditions conducive to homogeneous charge compression ignition operation. Nominal valve timing is selected and adjustments thereto are made based on deviations in combustion phasing from a desired combustion phasing. Fuel delivery timing and quantity are adjusted once valve timing authority limits are reached to achieve further combustion phasing improvement.

Abstract: A four-stroke internal combustion engine is operated in controlled auto-ignition mode by any of a variety of valve control strategies conducive to controlled auto-ignition conditions in conjunction with in-cylinder fuel charges that are at either stoichiometric or lean of stoichiometric air-fuel ratios. A measure of engine NOx emission is provided and when it crosses a predetermined threshold, the in-cylinder fuel charge is transitioned from the operative one of the stoichiometric or lean of stoichiometric air-fuel ratios to the inoperative one of the stoichiometric or lean of stoichiometric air-fuel ratios.

Abstract: Part load operating point for a controlled auto-ignition four-stroke internal combustion engine is reduced without compromising combustion stability through a valve control operative to establish low pressure conditions within the combustion chamber into which fuel and exhaust gases are introduced. Combustion chamber pressures during the intake cycle are controlled lower as engine load decreases. Combusted gases are recirculated into the combustion chamber through a variety of internal and external recirculation mechanizations. A split-injection fuel control is implemented during low part load operation whereas a single-injection fuel control is implemented during intermediate and high part load operation. Split-injections are characterized by lean fuel/air ratios and single-injections are characterized by either lean or stoichiometric fuel/air ratios. Controlled autoignition is thereby enabled through an extended range of engine loads while maintaining acceptable combustion stability and emissions.
