摘要： A control system (12) for an engine (10) having a combustion chamber (22) is disclosed. The control system may have a fuel injector (40) configured to selectively inject fuel into the combustion chamber, and a controller (54) in communication with the fuel injector. The controller may be configured to activate the fuel injector during a first compression stroke to initiate fuel injection in an amount and at a timing that results in a stratified lean air/fuel mixture within the combustion chamber during a first combustion event of a six- stroke cycle. The controller may also be configured to activate the fuel injector during a first power stroke to initiate fuel injection in an amount and at a timing that results in a homogenous lean air/fuel mixture within the combustion chamber during a second combustion event of the same six-stroke cycle.

摘要： A method and apparatus are disclosed for controlling a hybrid energy system (10) including at least an energy source (12) having a maximum energy output and an energy storage device (14). The method includes determining (102) a first amount of energy indicative of an amount of energy associated with the current operating condition of the energy source and determining (106) a second amount of energy indicative of energy associated with the energy storage device. The method also includes estimating (104) a third amount of energy indicative of a difference between the first amount of energy and the maximum energy output.

摘要： The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. A computer controlled injector (20) intermittently injects an optimal amount of NOx reducing fluid into the exhaust passageway (11) from the engine (12). The optimal amount corresponds to an amount that will achieve optimal NOx reduction rates for the given engine operating condition and exhaust temperature. A computer (16) periodically senses the engine operating condition and the exhaust temperature, and calculates the appropriate injection amount. With appropriate deNOx and oxidation catalysts located downstream from the injector (20), the exhaust purification system (10) of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels.

摘要： The present invention is particularly applicable to lean burn engines that produce exhaust containing insufficient amounts of unburned hydrocarbons to satisfactorily reduce NOx emissions without undermining engine performance. In the exhaust purification system (10), ethanol or another suitable hydrocarbon (19) is injected into the exhaust stream at an appropriate location between the engine and the catalytic converter (12). A deNOx catalytic converter (22, 122, 222) is positioned within the exhaust downstream from the ethanol injection point. The combination engine application, ethanol injection and suitable deNOx catalyst combine to reduce NOx to satisfactory levels without producing significant amounts of undesirable secondary nitrogen containing compounds. An oxidation catalytic converter (24, 124, 224) is positioned in the exhaust downstream from the deNOx catalytic converter (22, 122, 222). The oxidation catalyst serves to convert any remaining unburned hydrocarbons (19) into carbon dioxide and water. At the same time, only small amounts of secondary nitrogen compounds are converted back into NOx compounds upon passage through the oxidation catalyst. The end result being an overall reduction in both HC and NOx compounds particularly for lean burn engines to satisfactory levels.
