The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. The emissions purification system causes an after-injection of fuel through the engine fuel injector during the exhaust stroke of an internal combustion engine. A computer controls the injector to inject an optimal amount of NOx reducing fuel into the engine cylinder. 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 periodically senses the engine operating condition and determines the exhaust temperature, and calculates the appropriate injection amount. With appropriate deNOx and oxidation catalysts located downstream from the injector, the emissions purification system of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels and greatly reducing system complexity.

The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. The emissions purification system causes the addition of an optimal amount of fuel through the engine fuel injector after closure of the fuel injector needle check valve by enlarging the fuel injector SAC volume. The optimal amount corresponds to an amount that will achieve optimal NOx reduction rates for the given engine operating condition and exhaust temperature when the exhaust is passes through appropriate deNOx and oxidation catalysts located downstream from the injector. The emissions purification system of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels and greatly reducing system complexity.

A method and apparatus are disclosed for controlling a hybrid energy system including at least an energy source having a maximum energy output and an energy storage device. The method includes determining a first amount of energy indicative of an amount of energy associated with the current operating condition of the energy source and determining a second amount of energy indicative of energy associated with the energy storage device. The method also includes estimating a third amount of energy indicative of a difference between the first amount of energy and the maximum energy output. The method further includes controlling the energy source as a function of the second and third amounts of energy.

The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. A computer controlled injector intermittently injects an optimal amount of NOx reducing fluid into the exhaust passageway from the engine. 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 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, the exhaust purification system of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels.

Past methods for starting an engine have included increasing the amount of fuel to support combustion creating an excess of unburned fuel in the exhaust causing white smoke. Such past methods for starting an engine additionally required additional components, such as heater, and required an excessive draw on the battery to provide extensive glow plug operation and extensive cranking. The present method of starting an engine reduces and essentially eliminates white smoke, reduces the need for extensive glow plug operation and reduces the need for extensive cranking. The method of starting an engine includes the steps of: positioning an intake valve in a closed position; positioning an exhaust valve in a closed position; rotating a piston to a top dead center position; rotating the piston from the top dead center position toward a bottom dead center position; and injecting a fuel into the cylinder.

A power train is provided having a power source for generating a power output. The power train also has a power storage device for storing and distributing power. The power train further has a controller configured to cause the distribution of power from the power storage device for assisting the power source when the rate of fuel entering the power source is above a threshold fuel rate. The threshold fuel rate is a fuel rate at which, assisting the power source increases the efficiency of the power train.

A power system has a prime mover. The power system may also include a multiple-ratio transmission having a rotary input member and a rotary output member. Additionally, the power system may include a coupler connected between the prime mover and the rotary input member of the multiple-ratio transmission. The power system may also include an electric machine. Additionally, the power system may include power-system controls operable to automatically control whether the rotary input member of the multiple-ratio transmission is drivingly connected to the prime mover, including automatically controlling whether the coupler has a power-transmitting operating state. The power-system controls may also be configured to operate the electric machine to reduce the speed of the prime mover in concert with an upshift of the multiple-ratio transmission.
