    • 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.

    • An arrangement for controlling diesel engine fuel injection including a first sensor that detects engine temperature and a second sensor that detects outside air temperature. An associated electronic control unit adjusts the amount of advance of pilot injection timing relative to main injection timing based on the difference between the engine temperature and the outside air temperature. Since the amount of advance is determined based on the engine temperature and the outside air temperature, the warmup state of an engine is considered in determining the amount of advance. This means that differences in the temperature inside an engine cylinder are considered. Accordingly, it is possible to obtain an optimum amount of advance.
