摘要： A system and method for controlling a compression ignition internal combustion engine having an electronic control module with an idle shutdown feature to automatically stop the engine after idling for a period of time include determining whether the engine is being loaded and overriding the idle shutdown feature to keep the engine running when the engine is being loaded. In one embodiment, the present invention includes monitoring operating conditions to determine that the vehicle is stationary, monitoring the engine to determine the engine is idling, initiating a timer/counter to provide an indication of idling time, determining that the engine is operating in an auxiliary power mode, determining engine load, and automatically stopping the engine when the idling time exceeds a first threshold and the engine load is less than a second threshold. The present invention makes it more difficult for engine operators to defeat the idle shutdown feature by detecting current engine operating conditions to verify that the selected operating mode is consistent with current engine operating conditions.

摘要： A method of operating an engine during an over temperature condition to protect the engine, an information recording medium incorporating a computer program implementing this protection method, and an electronic control module that performs this protection method are disclosed. A torque value representative of an engine generated torque is recorded in response to an engine temperature exceeding a protection temperature threshold. The engine torque is then reduced as a nonlinear function of the temperature signal and the recorded torque value to promote engine cooling.

摘要： An engine control system for a compression ignition engine employs a microprocessor-based controller that detects engine operation in a speed range previously determined to be undesirable, and responding to the detection by changing operation of the engine. In the preferred embodiment, the controller commands a parameter for adjusting engine operation to reach a different speed outside of first and second thresholds defining the undesirable range in a time period subsequent to the detection.

摘要： A snow blower, vehicle having a blower engine and a propulsion engine is provided with a drvice for limiting the speed of operation of the snow blower vehicle if the blower engine is overloaded. A first signal is transmitted to the propulsion engine when the blower engine is overloaded and a second signal is transmitted to the propulsion engine when the blower engine is no longer being overloaded. The first signal may be provided to the propulsion engine to automatically limit the output thereof or it may be provided to generate an operator perceptible warning to the operator of the vehicle. The second signal may be provided to the propulsion engine to discontinue the limitation of the output of the propulsion engine or to stop the generation of the warning. A method of improving snow blower performance by increasing the ability of the blower engine to blow snow by limiting the output of the propulsion engine.

摘要： An exemplary transmission system includes a plurality of sensors each configured to output a signal at least partially representative of a speed of at least one of a first transmission input shaft, a second transmission input shaft, a transmission output shaft, and an engine. A transmission control module is in communication with the plurality of sensors and is configured to identify at least one of the plurality of sensors as a failed sensor and another of the plurality of sensors as a working sensor. The transmission control module is further configured to estimate the signal of the failed sensor based on a predetermined relationship between an expected signal from the failed sensor and the signal received from the working sensor.
