摘要： A control system and method for protecting engine electronic circuitry from thermal damage including an electronic controller coupled to the engine, and one or more sensors coupled to the controller for inputting at least one signal indicative of a condition which can be correlated to the temperature of the electronic circuitry. The controller is operable to establish the temperature of the electronic circuitry based upon the at least one sensor input and to output a signal to effectively lower the temperature of the electronic circuitry when the temperature of such circuitry exceeds a predetermined threshold temperature. The sensor inputs to determine or establish a correlation between the input signal and the temperature of the electronic circuitry may include sensing engine speed, sensing the voltage level of the power source providing electrical power to the circuitry, or sensing the temperature of the circuitry directly. The signal outputted by the controller to effectively lower the temperature of the circuitry may include a signal to control the number of fuel shots delivered to the engine during a particular fuel injection event, and/or the firing frequency of the fuel injectors, and/or a signal to restrict engine performance for at least a specified period of time.

摘要： A method for transitioning between a first engine operating mode and a second engine operating mode of an internal combustion engine involves establishing an engine mode transition region between the first engine operating mode and the second engine operating mode, which engine mode transition region is defined by at least one engine operating parameter. The engine operating parameter which defines the engine mode transition region is monitored. When the engine is operating in the transition region a first engine operating mode fuel rate is determined, a second engine operating mode fuel rate is determined, and an engine mode transition region fuel rate is determined which is a function of both the first engine operating mode fuel rate and the second engine operating mode fuel rate.

摘要： Apparatuses and methods for delivering fuel to at least two combustion chambers of an engine. A fuel controller receives a first fuel quantity signal indicative of a first desired quantity of fuel to be delivered to each combustion chamber of the engine during a combustion cycle. The fuel controller transmits at least one second fuel quantity signal as a function of the first fuel quantity signal, and transmits at least one third fuel quantity signal as a function of the first fuel quantity signal. The second and third fuel quantity signals are indicative of a respective second and third desired quantities of fuel to be delivered during a combustion cycle. The sum of the fuel quantities corresponding to the second fuel quantity signals transmitted during a combustion cycle are less than the first desired fuel quantity.

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.

摘要： An exhaust gas heating system and method of a direct injection compression ignition internal combustion engine which has a plurality of combustion chambers, an exhaust passage, and one or more direct fuel injection devices, each operable to inject fuel directly into a corresponding one of the combustion chambers. The system also includes a fuel injection controller which is operable to provide to at least one of the direct fuel injection devices, a post fuel injection signal during a corresponding cylinder cycle of the corresponding one of the plurality of combustion chambers. The post fuel injection signal is timed so as to provide exhaust gas heating from a resultant post fuel injection, and the fuel injection controller dynamically determines the particular one or more of the plurality of direct fuel injection devices to which the post fuel injection signal will be applied based on a temperature related engine operating parameter such as a desired amount of exhaust gas heating. The post fuel injection may also be timed and/or shaped such that it does not produce a substantial amount of mechanical energy but instead produces heated exhaust gasses.

摘要： A pulse width modulation driver provides programmable current control for a variety of load current ranges using a modulation feedback block. The block scales a signal representative of a sensed current flowing through the load by a selectable gain multiplier. The scaled signal is compared to a target current value to indicate to a driver control when to generate trigger signals for switching current through the load. In this way, load currents can be amplified to match the operational range of the comparator.
