  • Patent number: 7299781
    Abstract: An oil return passage for returning oil from a cylinder head to an oil pan is arranged along the downward first side surface of an engine that is mounted in a vehicle such that a center axis of a cylinder thereof is slanted with respect to a vertical direction of the vehicle. An oil return extension pipe is coupled to an outlet end of the oil return passage, and extends toward a second side surface of the engine that is opposite from the first side surface on which the oil return passage is provided. Thus, engine oil can be reliably returned to the oil pan from the cylinder head of the engine even when the vehicle is experiencing high acceleration in a direction that tends to cause backflow of the oil through the engine oil return system.

  • Patent number: 7258109
    Abstract: A method for operating a fuel injection device, particularly of a motor vehicle. The fuel injection device is provided with an injection valve which has a piezoelectric element. In using the method, the piezoelectric element is activated in such a way that the injection valve goes over into an opened state. During the activation, an electrical voltage is ascertained and/or prespecified at the piezoelectric element and/or an electrical current is ascertained and/or specified via the piezoelectric element. From the path of the voltage and/or from the path of the current one may infer the point in time of opening of the injection valve.

  • Patent number: 7255081
    Abstract: The present invention relates to methods for charging at least one combustion chamber (12) of a spark-ignition combustion engine (10) with fuel and air. At least one combustion chamber charge is produced during a shutoff phase of the internal-combustion engine (10) and is ignited when the internal-combustion engine (10) is subsequently started. The methods are characterized in that, during the shutoff phase, at least one measure is taken to produce a high percentage of fuel vapor in the combustion chamber charge. The present invention also relates to a control unit for controlling the methods.

  • Patent number: 7252073
    Abstract: Each of paired centrifugal weights are interlockingly connected to an advancing spring, which is interlockingly connected to a temperature-sensing operation device. When cold-starting the engine, the advancing spring is maintained extensible based on a state of the temperature-sensing operation in which the temperature-sensing operation device senses a temperature to operate. This advancing spring exerts a spring force, which pushes and widens the paired centrifugal weights to an advancing position. While the engine is warm, the advancing spring is held contracted based on another state of the temperature-sensing operation device, in which the temperature-sensing operation device senses a temperature to operate, so that the spring force of the advancing spring does not act on the paired centrifugal weights. A shape memory spring composed of a compression coil spring is used for the temperature-sensing operation device.

  • Patent number: 7207321
    Abstract: A fuel delivery system for supplying liquid gas fuel to an engine is disclosed. The fuel can be supplied solely to the engine or together with diesel fuel. The fuel delivery system includes an injector (20) for receiving the liquid gas, and for ejecting the liquid gas in vapour form to the engine E. A bubble preventing mechanism (40, 44, 48; 8, 203, 209, 208) is supplied for preventing the liquid gas from bubbling or boiling in the injector which would impair the ejection of fuel from the injector. The preventing means comprises cooling means which may use a coolant to cool the injector. In one embodiment, the coolant is in the form of bubbled vapour which is directed away from the injector (20) and enters a chamber (206) in which the injector (20) is located, so that the vapour cools the injector (20). The vapour (20) can pass to a vapour block (208) for supply to the intake air of the engine so the vapour is supplied back to the engine together with fuel ejected by the injector (20).

  • Patent number: 7201160
    Abstract: An air-fuel ratio sensor monitor is provided which is designed to monitor reactive characteristics or response rates of an air-fuel ratio sensor when an air-fuel ratio of a mixture to an internal combustion engine is changing to a rich side and to a lean side. The monitored response rates are used in determining whether the sensor is failing or not, in determining the air-fuel ratio of the mixture accurately, or in air-fuel ratio control of the engine.
