摘要： A method of estimating an injection pressure for an internal combustion engine of an automotive system is disclosed that is well-suited for use with a digital pressure sensor, which periodically acquires injection pressure signals. An updated injection pressure value is calculated starting from an injection pressure signal and compensated with a pressure-correcting parameter, based on an elapsed time from the injection pressure signal acquisition, an actual engine speed and an actual fuel injection quantity.

摘要： An internal combustion engine has a fuel injector that is controlled by an engine control unit. According to one embodiment a device receives from a temperature sensor information corresponding to the temperature of the engine. The device transmits substitute temperature information to the engine control unit when the temperature of the engine is within a predetermined range of temperatures. The substitute temperature information corresponds to a temperature that is different than the actual temperature of the ICE. The engine control unit controls the fuel injector so that it operates in response to the substitute temperature information.

摘要： A method of controlling a concentration of hydrocarbons in exhaust gas from an internal combustion engine includes sensing an oxygen percentage of the flow of exhaust gas from the internal combustion engine and determining a concentration of hydrocarbons in the flow of exhaust gas. An engine control module may then adjust the sensed oxygen percentage of the exhaust gas based on the determined concentration of hydrocarbons in the flow of exhaust gas to define a corrected oxygen percentage. The control module may then control at least one of a hydrocarbon injection rate for in-cylinder combustion of the internal combustion engine, and a hydrocarbon injection rate for a post combustion exhaust gas treatment process, based on the corrected oxygen percentage, to control the concentration of hydrocarbons in the exhaust gas.

摘要： An internal combustion engine includes an electronic controller programmed to determine, for at least one combustion event in a combustion chamber, a theoretical polytropic constant, a measured polytropic constant, and a difference between the theoretical polytropic constant and the measured polytropic constant. The electronic controller is further programmed to calculate an adjusted pressure signal based on the pressure signal and the difference such that the adjusted pressure signal compensates for changes to an accuracy of the pressure sensor over time.

摘要： In a sensor control apparatus of a gas detection system, a multiplexer having received an instruction from a digital computation section outputs analog signals in the order of, for example, “signal 1, signal 2, signal 1, signal 3, signal 1, signal 4.” By outputting the analog signals while classifying each of them as a high occurrence-frequency signal which is high in output frequency or a low occurrence-frequency signal which is low in output frequency, the multiplexer can increase the sampling frequency of signal (analog signal of Vs+-COM voltage) which is the high occurrence-frequency signal. The sensor control apparatus can increase the sampling frequency in AD conversion of signal to a digital value, while suppressing an increase in the cost of an AD conversion section.

摘要： A method for the regulation of a temperature in an exhaust stream in a motor vehicle through control of its driveline: the motor vehicle includes a driveline having a combustion engine, which may be connected to a gearbox via a clutch device, and an exhaust system for removing an exhaust stream from the engine. The method includes controlling the driveline for activation or deactivation of coasting of the vehicle based on one or several first parameters P1 and one or several second parameters P2 for regulation of a temperature TEx in the exhaust system. At least one of the first parameters P1 is a first temperature difference between the first temperature T1 in the exhaust system and a reference temperature TREF. The said second parameter P2 is related to a calculated speed and/or a calculated road inclination over the road section ahead for the motor vehicle. Further, a computer program, a computer program product, a system and a motor vehicle including such a system are disclosed.
