Abstract: A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.

Abstract: A fuel injection control device for an internal combustion engine includes an electronic control unit configured to execute division processing for learning for dividing a requested injection amount into an injection amount of partial lift injection of an in-cylinder injection valve and a port injection amount of injection of a port injection valve, detect, on the basis of at least one of a terminal electric potential of a coil and a current flowing through the coil, an inflection point of a change in induced electromotive force of the coil in time attributable to a decline in a relative speed of a mover with respect to the coil, and correct the energization processing at a time when the partial lift injection is executed based on a timing of the detection of the inflection point.

Abstract: Various methods and systems are provided for estimating fresh intake air flow. In one example, a system comprises an engine having an intake manifold to receive fresh intake air and an exhaust gas recirculation (EGR) system to supply EGR to the intake manifold, where flow of EGR through the EGR system is controlled by one or more exhaust valves. The system further includes a controller configured to adjust a position of the one or more exhaust valves based on an estimated fresh intake air flow rate, where during a first set of operating conditions, the fresh intake air flow rate is estimated based on a total gas flow rate into the engine and further based on a current position of the one or more exhaust valves, intake manifold pressure, air-fuel ratio, and fuel flow to one or more cylinders of the engine.

Abstract: A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

Abstract: A fuel property determination apparatus for an internal combustion engine is applied to an internal combustion engine that is equipped with an ignition plug and an ignition timing controller. An electronic control unit provided in the fuel property determination apparatus executes a determination process of making a determination on a property of a fuel supplied to the internal combustion engine based on an ignition sufficiency ratio, during a predetermined period after startup of the internal combustion engine. The electronic control unit is configured to determine that the property of the fuel is heavy when a determination index value that is obtained by subjecting the ignition sufficiency ratio to a smoothing process is equal to or larger than a predetermined threshold. The electronic control unit is configured to set a smoothing coefficient to a value corresponding to each of a first period, a second period, and a third period.

Abstract: A control apparatus for a vehicle may include an engine, a fuel tank, a feed pump, a pressure sensor, a motor and an electric storage apparatus. The feed pump feeds the fuel to a port injection valve. The pressure sensor detects a fuel pressure that is fed to the port injection valve. The motor performs cranking of the engine at start time of the engine. The control apparatus includes an ECU. The ECU controls the feed pump based on a detection value of the pressure sensor and controls the motor in order to start the engine. The ECU controls the feed pump and the motor such that the electric storage apparatus feeds electric power to the motor in preference to the feed pump, when an electric power that the electric storage apparatus is able to output at the start time of the engine is less than a determination threshold.

Abstract: Various methods and arrangements for controlling catalytic converter temperature are described. In one aspect, an engine controller includes a catalytic monitor and a firing timing determination unit. The catalytic monitor obtains data relating to a temperature of a catalytic converter. Based at least partly on this data, the firing timing determination unit generates a firing sequence for operating the engine in a skip fire manner. Another aspect of the invention relates to an engine exhaust system that can help expedite the heating of a catalytic converter.

Abstract: Methods and systems are provided for control of a combustion engine in a vehicle. In operation, at least one future speed profile for an actual speed of the vehicle is simulated during a road section ahead based on information about the road section and on knowledge that coasting with the combustion engine shut down will be applied during the road section. Subsequently, based on the future speed profile, a starting point in time is determined, when the combustion engine will need to be started for forward driving the vehicle and/or to brake the vehicle. Subsequently, a starting point brought forward in time is determined based on the need for a forward driving or braking force arising, where the starting point brought forward in time precedes the starting point in time. Subsequently, the combustion engine is controlled to be started at the starting point brought forward in time.
