    摘要: An exhaust aftertreatment system including an exhaust flow area, a first bank of one or more exhaust treatment devices in fluid communication with the exhaust flow area and a second bank of one or more exhaust treatment devices in fluid communication with the exhaust flow area. The first bank may be arranged in parallel with the second bank and inlet of the first bank is configured to provide greater flow resistance to the exhaust than the inlet of the second bank.

    摘要: Starting systems for use with internal combustion engine have in the past used a variety of add on mechanical mechanisms to provide cold starting. Many of these systems fail to provide the option of controllably and modulatively varying the sequence and amount of the opening and closing of an intake or exhaust valve relative to a piston position in a cylinder bore. The present invention provides an electronic control system outputting an discrete control signal, and an opening device for unit actuation of each of the pair of valves independently. The electronic control system is programmable to respond in a first predetermined logic pattern for conventional operation of the engine at which time each of the pair of valves is in the open position during the exhaust stroke. The electronic control system is programmable to a second predetermined logic pattern to vary the operation of the valves associated with the respective bore in the generally closed position for a portion of the exhaust stroke before top dead center during the exhaust stroke of the piston. The preestablished logic pattern controllably, sequentially and modulateably actuate the device for unit actuation, moving each of the valves independently between the open and closed position to effectively increase the heat within the during the movement of a piston from a bottom dead center position to a top dead center position.
