摘要： A powertrain including an HCCI engine is disclosed. The HCCI engine is configured to supply mechanical power, and a generator operably coupled to the HCCI engine is configured to convert at least a portion of the mechanical power into one of electric energy and hydraulic energy. The powertrain further includes a motor operably coupled to the generator. The powertrain also includes an energy storage device operably coupled to the generator and the motor. The powertrain further includes a controller configured to control the powertrain such that energy stored in the energy storage device is supplied to the motor when the HCCI engine supplies insufficient mechanical power to the generator to supply the motor with sufficient power to meet power requirements of the powertrain, until the HCCI engine supplies sufficient mechanical power to the generator to supply the motor with sufficient power to meet the power requirements of the powertrain.

摘要： A method of operating an engine system should produce relatively low concentrations of various emissions without compromising a desired power output of the system. In order to operate an engine system of the present disclosure, a predetermined total amount of fuel injected into at least one combustion chamber is apportioned into at least a first amount and a second amount of fuel. The first amount of fuel is injected into the at least one combustion chamber during non-auto ignition conditions. The second amount of fuel is injected into the at least one combustion chamber during auto-ignition conditions. When the engine system is in a mid-low engine load range, the second amount of fuel is one of equal to or less than 15% of the predetermined total amount of fuel. When the engine system is in a high engine load range, the second amount of fuel is greater than 15% of the predetermined total amount of fuel.

摘要： A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injection device, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions of the engine, the controller being operable to output a fuel injection signal to the fuel injection device to deliver pilot, main, and anchor fuel shots to the cylinder during a fuel injection event based upon the sensor signals. The controller also divides the desired fuel quantity between the three shots. In dividing the total fuel set by the governor system between the three shots, the controller determines desired pilot and anchor fuel shot amounts and also determines minimum pilot, main, and anchor fuel shot amounts. By comparing the total fuel with various sums of the desired and minimum fuel amounts, actual fuel amounts for each shot are determined with the main shot given first priority, the pilot shot given second priority, and the anchor shot given third priority.
