Title: Fuel injection control device for internal combustion engine
Inventor: SHODA YASUSHI
IPC: F02D41/02
Filed: 2014-09-05
Abstract: PROBLEM TO BE SOLVED: To suppress the worsening of a combustion state resulting from a change in the fuel injection state of a fuel injection valve due to deposits and the like, in a system for executing intake valve opening injection control.SOLUTION: A fuel injection control device determines whether the combustion state of an engine 11 is worsened or not during executing intake valve opening injection control to inject fuel in a period for opening an intake valve 30. When determining that the combustion state of the engine 11 is worsened, it deems the combustion state to be worsened since a change in the fuel injection state (the atomization of injected fuel and the distribution of spray) of a fuel injection valve 21 due to deposits accumulated thereon precludes sufficient atomization of the fuel in the intake valve opening injection control, and switches the intake valve opening injection control into intake valve closing injection control. In the intake valve closing injection control, the fuel is injected in a period for closing the intake valve 30 before opened. Thus, a time from injection to combustion is elongated to elongate a time for atomizing the fuel, and thus the fuel is sufficiently atomized to suppress the worsening of the combustion state.SELECTED DRAWING: Figure 1

Filed: 2014-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a redundant control system in which availability is improved by reducing, compared to a conventional system, an occurence frequency of switching between an active system and a standby system.SOLUTION: A relay device that is connected via a network device connection bus to one of two control devices, one of which serves as an active system and the other of which serves as a standby system, and also connected to an IO network, is connected to the other control device via redundant communication means. The relay device is further connected, via an equalization cable, to the other relay device that is connected to the other control device via the network device connection bus. When a connection destination of the network device connection bus is the active system, at least one of processing for transferring monitoring data received from the IO network to the control device of the active system and processing for transferring the monitoring data to the other relay device is executed. When the connection destination of the network device connection bus is the standby system, processing for transferring the monitoring data received via the equalization cable to the control device of the active system via the redundant communication means is executed.SELECTED DRAWING: Figure 4

Title: Engine control device
Inventor: USHITANI MASAKI
IPC: F02D45/00
Filed: 2014-09-16
Abstract: PROBLEM TO BE SOLVED: To suppress increase in combustion sound occurring in transition to a high load region with a low EGR rate, and occurrence of smoke simultaneously.SOLUTION: An engine control device increases an amount of fuel in acceleration to increase boost pressure, while sets an upper value to a fuel injection amount so that an exhaust oxygen concentration is not less than a predetermined threshold. When it is determined that an EGR supply region in which exhaust is recirculated to a suction system in acceleration is transited to a region having a low EGR rate in which exhaust is not recirculated, the engine control device lowers fuel pressure, and suppresses increase in amount of fuel once with reduction in fuel pressure.SELECTED DRAWING: Figure 5

Title: Clinch pin-type panel fastener
Inventor: MICHAEL MALONEY
IPC: F16B19/06
Filed: 2014-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a clinch type panel fastener formed by simultaneously creating an undercut during the same forging process that creates a head and a displacement function portion of the panel fastener.SOLUTION: A panel fastener blank is compressed end-to-end between top and bottom dies, and thereby the axial compression of a blank causes the outward bulging of a shank at its midline. Simultaneously, a tapered end point 16 and a tangential interference band 18 are formed by a curvilinear-shaped bulge in the shank. During the formation of the bulge, an undercut 15 is created between the bulge and a shoulder portion which extends downward from a head of the fastener. This method of formation and the panel fastener produced thereby are particularly suited to the manufacture of a small clinch pin having a diameter in the range of 1.0 mm.
