摘要： Control device of an internal combustion engine that determines whether or not to perform sensor element heating control of an air-fuel ratio sensor with high accuracy based on the mass of condensed water in an exhaust pipe. The control device computes the rate of change of condensed water mass in an exhaust pipe based on the saturated water vapor pressure and the water vapor partial pressure of exhaust gas, and computes the rate of change of evaporation mass in the exhaust pipe based on the amount of heat which the condensed water receives in the exhaust pipe. The control device updates the mass of condensed water based on the rate of change of condensed water mass and the rate of change of evaporation mass, and determines whether or not to perform heating control by a heating controlling unit based on the updated mass of condensed water.

摘要： A sheet feeder has a tray on which a sheet to be fed is to be placed. A lift plate is at a feeding end of the tray and has a first end at an upstream side in a feeding direction connected rotatably to the tray. The lift plate is displaceable between a feeding posture where a second end at a downstream side in the feeding direction is lifted up and a retracted posture where the second end is lower than in the feeding posture due to its own weight. A biasing member gives a biasing force to an elevating member in a direction to lift the lift plate to the feeding posture. A lowering mechanism gives a pressing force against the force of the biasing member to lower the lift plate to the retracted posture.

摘要： In a system which applies a torque-based control to a direct injection engine with a turbocharger and is capable of switching between stoichiometric running and lean-burn running in accordance with a driving state, in order to provide a means for obtaining preferred exhaust performance and driveability, a turbo lag index is computed on the basis of supercharged pressure information or air intake pipe pressure information which are obtained directly or indirectly, and then a throttle opening or a fuel injection quantity is corrected on the basis of the above-described turbo lag index to obtain desired torque and exhaust characteristics. As a result, it is possible to prevent a torque variation, a change in torque characteristics, exhaust deterioration, or the like in a transient time, which are generated due to a turbo lag.

摘要： A misfire detector is provided that is accurate even in the case of a disturbance due to causes such as driving on a rough road. The misfire detector is equipped with a crankshaft revolution detector to measure the time period required for the crankshaft of an internal-combustion engine to revolve for a given angle. A signal-processor is also provided for detecting the misfiring of the internal-combustion engine by processing the time period. In one embodiment, the misfire detector has two filters having the same sensitivity to the misfire frequency, and differing in the sensitivity to frequencies adjacent to said misfire frequency. It can be determined that a misfire has occurred if the ratio or difference between the outputs of the two filters stays within a fixed range and one or both of the filters have respective outputs exceeding a threshold value.
