摘要： Disclosed is a control device applied to an internal combustion engine provided with a fuel vapor treatment system for treating collected fuel vapor by purging the collected fuel vapor into intake air downstream from an air flowmeter (6) and an exhaust gas recirculation system for recirculating part of exhaust gas in the intake air using intake negative pressure. An electronic control unit (22) performs an advance correction corresponding to the exhaust gas recirculation quantity regarding the MBT ignition timing and the knock limit ignition timing, and corrects the volumetric efficiency of the internal combustion engine, which is used for the calculation of the advance correction quantity used for the advance correction, according to the purge air quantity. Consequently, regardless of the decrease of the exhaust gas recirculation quantity caused by the implementation of a large quantity of purge, the appropriate advance corrections of the MBT ignition timing and the knock limit ignition timing become possible.

摘要： An internal combustion engine system is reticulated into an exhaustive network of interdependent temperature nodes and heat transfer branches for estimating thermal states at various nodes as required in engine control and diagnostic operations. All material heat transfer processes of each node of interest in engine control and diagnostics are modeled with additional nodes and their respective heat transfer processes added as necessary for a comprehensive analysis of all thermal dependencies, resulting in a precise, generic, portable thermal model for each relevant engine system temperature node.

摘要： A straddled vehicle having a failure detector with improved accuracy in the detection of a failure of a temperature sensor is provided. A failure detector (93, 94) detects a failure of a temperature sensor (72, 75) based on at least one signal of the temperature sensor (72, 75), at least one generated heat amount-related parameter, and at least one dissipated heat amount-related parameter. The generated heat amount-related parameter relates to an amount of heat generated in an engine unit and influencing the temperature of a detection target of the temperature sensor (72, 75) and further relates to a state of the straddled vehicle. The dissipated heat amount-related parameter relates to an amount of heat taken away from the straddled vehicle as the straddled vehicle runs and influencing the temperature of the detection target of the temperature sensor (72, 75) and further relates to an environment of the straddled vehicle.

摘要： A system (100) is described for modeling various states of an operating engine and the adjustment of one or more operating characteristics of the engine based upon such modeling. A representative rate of change of a system mass for an engine is determined based upon, at least in part, a first state equation (102). A first representative mass flow approximating a mass flow across a throttle is determined based upon, at least in part, a second state equation (104). A second representative mass flow approximating a mass flow across an exhaust gas recirculation valve is determined based upon, at least in part, a third state equation (108). Determining the first representative mass flow includes specifying a throttle time constant modifier for the second state equation (106). Determining the second representative mass flow includes specifying an exhaust gas recirculation valve time constant modifier for the third state equation (110).
