  • Patent number: 8534239
    Abstract: It is an object of the invention to provide a multi-cylinder diesel engine in which a thermal damage of a common rail, and a rise in fuel temperature can be suppressed. In order to achieve the object, a multi-cylinder diesel engine in which, while the extension direction of a crank shaft 1 is set to the anteroposterior direction, a common rail 3 which is directed in the anteroposterior direction is placed above an intake manifold 2, and an engine cooling fan 4 is placed in front of the engine is configured so that the width direction of the engine which is perpendicular to the anteroposterior direction is set to the lateral direction, an air intake portion 6 of the intake manifold 2 is placed on the outer lateral side of the both lateral sides of the common rail 3, the outer lateral side being opposite to a head cover 5, and the common rail 3 is placed in a place to which engine cooling air produced by the engine cooling fan 4 is blown.

  • Publication number: 20020033169
    Abstract: A fuel meter (21) of a fuel injection pump is made movable for fuel metering through a governor lever (14). A swing lever (31) has a power input point (J) which engages with a boost actuator (26). If the boost actuator (26) operates in response to a delayed rise of a supercharged pressure (P), a power output point (K) of the swing lever (31) inhibits the fuel meter (21) from moving for fuel increase. A governor lever (14) is connectably and separably opposed to the fuel meter (21) from a fuel increase side and a start spring (18) urges the fuel meter (21) toward a starting fuel increase side. The swing lever (31) has a pivot axis (Q) displaceable by an actuator (40). When making a cold start, the actuator (40) does not operate to thereby confine the fuel meter (21) to a starting fuel increase position by the power output point (K) positioned on a fuel increase side.

  • Patent number: 4505673
    Abstract: Original models of plaster are obtained from impressions of the dentition of the upper and lower jaws of a patient with malocclusion. The teeth are then separated from the base of the models and reset in wax to a normal occlusion. The realigned teeth are fixed in place with wax, and impressions of the upper and lower models are taken to duplicate the rearranged models, forming working models made of plaster. The working models are mounted on an anatomic dental articulator and a wax occluding model is constructed of the new occlusion to cover both upper and lower arches. The working upper and lower models, together with the wax occluding model are buried in plaster in a split cast. The wax occluding model in the split cast is heated and the wax is melted and discharged out of the cast. Silicone resin is then placed into the impression of the occluding model and cured.
