  • Publication number: 20100107992
    Abstract: Retractable leashes use a braking mechanism to stop a dog from movement. A mechanism is provided for smoothly or gradually braking the unreeling of the line, and can include a brake with a pad or pads for stopping the dog much like a bicycle. The brake and pads allow the user to squeeze the trigger lightly or more aggressively to slow and stop the dog's movement without the sudden jerk of traditional retractable leashes. The consumer may ultimately clamp down on the trigger to clamp the pads to the reel instantly for an aggressive stop if needed.

  • Publication number: 20100107994
    Abstract: A method and device to optimize the cumulative beneficial effect of harvesting available forms of lost energy, including energy that is lost while a vehicle is in motion (e.g., kinetic energy and energy contained in electromagnetic radiation. The cumulative energy that is recovered is converted to electrical energy which powers the on-board electrolyzer to produce more hydrogen and oxygen while the system is in operation and stationary. Stationary, passive forms of energy (e.g., solar, wind, hydro, etc.) will also be available to power the electrolyzer. The system also contemplates using passive forms of energy to power a non-mobile system which incorporates an internal or external combustion engine in place of a fuel cell. An oxygen injection control device is employed to control the supply of oxygen to the combustion engine.

  • Publication number: 20100107995
    Abstract: When knocking occurs, a control apparatus for an internal combustion engine increases the rotational speed of a pump to increase the flow rate of a coolant supplied to an area near a combustion chamber wall surface, and controls an actual mechanical compression ratio to a low mechanical compression ratio lower than a mechanical compression ratio set based on the load of the engine. Thus, the pressure of end gas is decreased, and occurrence of knocking is suppressed. Then, the actual mechanical compression ratio is returned to the mechanical compression ratio at a time point at which the temperature of the combustion chamber wall surface has been sufficiently decreased due to the increase in the rotational speed. Thus, occurrence of knocking is suppressed while avoiding the situation where the actual mechanical compression ratio continues to be controlled to the low mechanical compression ratio that is lower than the mechanical compression ratio.

    Abstract: In a cross section in which squish flow from an outer peripheral part of a piston (13) toward a cavity (25) is large due to a width (W2) of a squish area (SA) being large and a squish clearance (C2) being small, a collision angle (?2) at which a fuel injection axis (Li2) collides with the cavity (25) is made large, whereas in a cross section in which squish flow is small due to the width of the squish area (SA) being small and the squish clearance being large, the collision angle at which a fuel injection axis collides with the cavity (25) is made small. This enables a tendency for fuel to flow out to the exterior of the cavity (25) in a cross section where the squish flow is small to be weakened, and a tendency for fuel to flow out to the exterior of the cavity (25) in a cross section where the squish flow is large to be strengthened, thereby making the conditions in which fuel and air are mixed uniform throughout the entire region of the cavity (25).

The bias piston biases the rocker arm out of contact with an engine cam during select engine operation modes, such as during a positive power mode of operation. The bias piston may be mechanically or hydraulically repositioned to permit the rocker arm to contact the engine cam during a second mode of engine operation, such as an engine braking mode.

  • Publication number: 20100108027
    Abstract: In a variable valve actuation system of an internal combustion engine employing a variable valve actuator capable of variably adjusting at least intake valve closure timing depending on engine operating conditions, a processor of a control unit is programmed to phase-advance the intake valve closure timing to a predetermined timing value after a piston top dead center position and before a piston bottom dead center position on intake stroke during at least one of an engine starting period and an engine stopping period. The variable valve actuator includes a biasing device by which the intake valve closure timing is permanently biased toward the predetermined timing value.

    Abstract: In an electronic control governor (1) that adjusts amount of fuel supplied to an engine so as to coincide an engine rotation speed with an target rotation speed, by driving an actuator (2) for actuating a fuel adjusting mean, due to an actuator driving current overlapped with a dither current, an amplitude or frequency of the dither current is changed, corresponding to change in supply quantity of the actuator driving current. Or, the amplitude and frequency of the dither current are changed, corresponding to change in the engine rotation speed. Alternatively, a ratio between turn-on time and turn-off time during one period of the dither current is changed, depending on velocity ratio between increased velocity and decreased velocity of the actuator driving current. Preferably, the ratio of the turn-on time to one period of the dither current is set at 20 to 40%.

  • Publication number: 20100108033
    Abstract: A method of controlling the combustion of a spark-ignition engine having application to gasoline engines is disclosed. An engine control system controls actuators so that the values of physical parameters linked with the combustion of a mixture of gas and fuel in a combustion chamber are equal to their setpoint values, to optimize the combustion. A setpoint value is determined for an ignition crank angle of the fuel mixture which is then corrected before the physical parameters reach their setpoint values. A correction to be applied to this ignition angle setpoint value is calculated so that the crank angle CAy is equal to its setpoint value. Finally, the engine control system controls the ignition of the mixture in the combustion chamber when the crank angle is equal to the corrected setpoint value to optimize combustion.
