    Abstract: A method of operating a hybrid homogenous-charge compression-ignition (HCCI) engine and spark ignition (SI) engine. The engine includes at least two cylinder groups, and each of the cylinder groups further include at least one cylinder. The method comprises the steps of detecting a transition request to transition the engine from a current operating mode to a desired operating mode. For example, a transition request from HCCI combustion mode to SI combustion mode, or vice versa. In response, the method transitions the first cylinder group from the current engine operating mode to the desired engine operating mode during a first time period, and transitions the second cylinder group from the current engine operating mode to the desired engine operating mode during a second time period. The second time period begins after the start of the first time period. In one aspect of the invention, the second time period begins after the end of the first time period, and in another aspect of the invention, the second time period overlaps the first time period.

    Abstract: A homogeneous charge compression ignition engine comprising an air intake passage, a combustion chamber connected to the air intake passage, and a partial oxidation device is disclosed. The partial oxidation device comprises a housing including a fuel inlet, an air inlet, an outlet, a mixing chamber and a burning chamber. The air inlet is connected to the air intake passage and the outlet is also connected to the air intake passage. A source of ignition is attached to the housing for causing ignition of a portion of a fuel-air mixture supplied to the housing. A partially oxidized fuel is produced as the combusting fuel-air mixture is rapidly quenched upon exiting the outlet of the housing and entering the air intake passage. Different structures for achieving rapid quenching are discussed and different air supply strategies are also presented. Further, another structure for producing a partially oxidized fuel using a low temperature chain propagating reaction is included. This structure comprises a glow plug or heat pipe disposed in the air intake passage for heating the fuel and causing it to react without complete combustion prior to entering the combustion chamber.

    Abstract: The present disclosure discloses an HCCI air intake system for HEV, wherein the air outlet of the compressor is simultaneously connected to a hot channel and a cold channel, the hot channel is connected to the cylinder of the HCCI gasoline engine via the electrical drive system, coolant heat exchanger, engine exhaust heat exchanger and a throttle valve, while the cold channel is directly connected to the cylinder of the HCCI gasoline engine via another throttle valve. The hot channel is provided with at least one bypass valve for discharging air. The present disclosure makes the best use of the features of the electrical drive system and the HCCI gasoline engine in the HEV to make them technically work with each other, and provides a united air circulation system to meet the need to cool down the electrical drive system while controlling the air intake temperature of the engine cylinder, thereby overcoming the difficulty in maintaining the temperature level caused by the fact that the HCCI gasoline engine in the HEV has to be shut down intermittently. The present disclosure, in combination with its controlling method, may decrease even further, with relatively lower cost, the mean gasoline consumption and exhaust discharge of vehicles.

    Abstract: Method and system embody a valve timing strategy to control the autoignition timing of a four stroke internal combustion engine (10) operated in an HCCI mode at different engine operating conditions such as different engine speed and torque. A particular valve timing strategy varies lift timing of the intake valve (20) relative to the exhaust valve (28), or vice versa, and relative to top dead center in response to a change in engine torque, for example, to vary amount of trapped residual burned gas in the combustion chamber (12) flowing to an intake or exhaust port (16,18) and back to the combustion chamber during which the residual gas is cooled. Control of the flow of residual gas between the combustion chamber and intake or exhaust port and thus its temperature by the valve timing strategy, in turn, is used to control the temperature of the fresh air/residual gas/fuel mixture in the combustion chamber (12) and thus autoignition timing in response to a change in engine torque.
