  • Publication number: 20160237940
    Abstract: An engine system includes a mass air flow sensor and a manifold absolute pressure sensor configured to provide a real-time MAP signal during an event. The mass air flow sensor is configured to generate a set of mass air flow readings based on an airflow through the mass air flow sensor during the event. The set of mass air flow readings have a maximum value and a minimum value. A controller is configured to execute a method for detecting reversion in the air flow. If the rate of change in the real-time MAP signal is less than the predetermined transient threshold value (T0), the method includes setting a delta factor (D) as the difference between the maximum value and the minimum value. Reversion is detected based at least partially on a magnitude of the delta factor (D).

    Abstract: An engine assembly includes an intake manifold and a manifold absolute pressure sensor configured to generate a current measured manifold absolute pressure (MAPM) signal for the intake manifold. The assembly includes a throttle valve adjustable to control airflow to the intake manifold and a throttle position sensor configured to generate a current measured throttle position (TPM) signal. A controller is operatively connected to the throttle valve and the manifold absolute pressure sensor and has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for determining a predicted manifold absolute pressure (MAPP). Execution of the instructions by the processor causes the controller to determine the predicted manifold absolute pressure (MAPP) based at least partially on a predicted throttle flow (TFP) and the current measured manifold absolute pressure (MAPM) signal.

    Abstract: An idling stop control device of the invention acquires an index (SOCx) indicating a magnitude of a remaining charged electric power amount of a battery (41), restarts an operation of an engine (25) by operating a starter (43) when the index becomes smaller than a predetermined restart threshold (SOCstart) while an automatic stop of the operation of the engine has been carried out, and changes the threshold from a first threshold (SOC1) to a second threshold (SOC2) when an operation of an electric actuator (31) is started while the automatic stop has been carried out. The first threshold is a threshold set immediately before the operation of the actuator is started and the second threshold is smaller than the first threshold.

  • Publication number: 20160237977
    Abstract: An internal combustion engine (1) may include a combustion chamber (41) into which a mixture (40) of fuel and air is supplied, a spark plug (50) disposed proximate to the combustion chamber (41) to ignite the mixture (40) by generating a spark such that ignition of the mixture drives a piston (6) operably coupled to a crank portion (12) of the engine (1), a speed sensor (102) configured to determine engine speed, and an electronic control unit (100) configured to control operation of the spark plug (50). The electronic control unit (100) may be configured to initiate a speed limitation operation in response to engine speed reaching a cut out speed threshold and to control ignition timing within an operating band (320) of ignition angles prior to engine speed reaching the cut out speed threshold. The speed limitation operation may include skipping application of sparks.

  • Publication number: 20160237978
    Abstract: A gear pump unit for hydroelectric power generation comprises a generator (138) and a control module operatively connected to a gear pump (131). The gear pump (131) comprises a case (131B) with a fluid inlet (132) and an outlet (135). A first rotor (133) comprises a first plurality of radially spaced teeth (133A, 133B, 133C) that wrap around the first rotor helically in a clockwise direction. A second rotor (134) comprises a second plurality of radially spaced teeth (134A, 134B, 134C) that wrap around the second rotor helically in a counter-clockwise direction. The first plurality of teeth mesh with the second plurality of teeth. The gear pump unit operates in a pump, turbine, or siphon mode via the control module 150 selectively rotating the first and second rotors. Electricity is generated by coupling the rotational energy of the first and second rotors to the generator (138).

  • Publication number: 20160237980
    Abstract: The invention relates to extracting kinetic energy from surface waves. Therein, at least one float (8) is kept floating in the area of the surface waves, while a working fluid is held in a reservoir structure (2, 3). The float is connected to a fluid displacement structure in such manner that an individual surface wave, which causes an upward stroke of the float, moves the working fluid within the reservoir structure in such manner that the potential energy of the working fluid is increased. Before the wave has reached the float, the wave is detected by a sensor (7). Based on said detection, a prediction is calculated of the amount of kinetic energy available in the wave. Tuned to said prediction, an energy transmission structure of the fluid displacement structure is adjusted for realizing the energy conversion.

    Abstract: A water turbine drive system is described for generating rotational power from a flowing water stream. The water turbine drive system comprises a rotating machine driven by a water turbine disposed remote from the machine, where the machine and turbine are connected together by a tether member adapted to be rotated by the turbine and transmit the rotation and thereby drive the machine. The tether member permits positional movement of the turbine relative to the machine such that the rotational axis of the turbine need not be co-aligned with the rotational axis of a driven rotating member of the machine.
