  • Patent number: 8352157
    Abstract: In an internal combustion engine, a variable compression ratio mechanism able to change a mechanical compression ratio and a variable valve timing mechanism able to control the closing timing of an intake valve are provided. The mechanical compression ratio is held at a maximum mechanical compression ratio at the engine low load operation side and gradually made to decrease as the engine load increases at the engine high load operation side. The actual compression ratio is held nearly constant at the engine high load operation side and is made to decrease as the engine load decreases at the engine low load operation side.

  • Patent number: 8350606
    Abstract: In a delay circuit for inputting square waves, fluctuations in the amount of delay brought about by noise pulses present in input signals are reduced. A switch (SW3) is controlled by an output signal (Vdo) from a Schmitt comparator, and selects either an electric current source for supplying a charging current to a capacitor (Cst) or an electric current source for supplying a discharging current. A current supply from the selected electric current source is turned on/off by controlling switches (SW1, SW2) using an input signal (Vdi). The Schmitt comparator switches the level of Vdo in accordance with a voltage of Cst. The charging current is supplied to Cst when Vdi is H level at rising edge of Vdi, and the discharging current is supplied to Cst when Vdi is L level at trailing edge of Vdi.

  • Patent number: 8352136
    Abstract: A vehicle control system for an engine-powered vehicle equipped with an engine and an automatic transmission with a clutch. When a given engine stop requirement is met during running of the engine, the system stops the engine automatically. When a given engine restart requirement is met after stop of the engine, the system restarts the engine and enters a clutch control mode to bring the clutch in the automatic transmission into a slippable state in which the clutch is permitted to slip based on the speed of the vehicle, thereby absorbing the acceleration shock which usually occurs upon engagement of the clutch to transmit engine torque to wheels of the vehicle when the engine is restarted, and the speed of the vehicle is relatively low.

  • Patent number: 8347604
    Abstract: The degree of deterioration of a catalyst is obtained accurately in cases where a plurality of catalysts is disposed at an exhaust passage of an internal combustion engine. Under the assumption that the degree of deterioration of a catalyst which is disposed at a location upstream of an NOx selective reduction catalyst and has an oxidizing ability is at a predetermined value, the ratio of NO2 in the NOx which inflows into the NOx selective reduction catalyst is estimated; the NOx removal rate of the NOx selective reduction catalyst is calculated a plurality of times at least until a local maximum value is obtained; and the degree of deterioration of the catalyst having an oxidizing ability is determined by comparison between the ratio of NO2 observed when the NOx removal rate of the NOx selective reduction catalyst reaches the local maximum value and a reference value of the ratio.
