摘要： The invention provides an in-cylinder injection type internal combustion engine that is capable of controlling gas flow velocity in the vicinity of an ignition part of a spark plug and maintaining an air-fuel mixture suitable for ignition for a long time. The engine includes deflecting parts 28 that have a passage 25 located on a wall face of a combustion chamber between an injection part 11 and an ignition part 17, and deflect a portion of the fuel injected from the injection part 11 to indirectly direct the fuel to the vicinity of the ignition part. Due to the above construction, there is a difference in reaching timing between direct and indirect routes, and moreover a flow velocity of gas that reaches the ignition part is reduced by fuel deflection. An air-fuel mixture suitable for ignition therefore remains in the vicinity of the ignition part for a long time.

摘要： In order to ensure waterproofing between a resin enclosure case and a heat sink, a canopy structure is provided in a portion, in which water is likely to penetrate, so as to prevent the water from entering the portion, thereby directing the water flow to the outside of the enclosure. This makes it easy to install and remove an electronic unit, so that an electronic component integrally formed with the heat sink can be easily replaced.

摘要： In an electronic throttle controller, when an intake air amount detected by an air flow meter is smaller than a stall prevention judging-purpose each cylinder intake amount, a stall prevention adding amount “large” is added to intake throttle opening degree deviation, a DC motor is driven while neglecting a feedback control operation, and an opening degree of the intake throttle is controlled to be further opened from an actual preceding control position. When an execution number of the engine stop avoiding control is larger than a predetermined number within a predetermined period, an abnormal condition of a throttle position sensor is detected, and thus, energizing operation of the DC motor is stopped. The abnormal condition malfunction of the throttle position sensor can be firmly detected while an engine stall is avoided.

摘要： In an electronic apparatus in which plural substrates are arranged in a perpendicular direction between plural cooling fans in a lower part of a case and plural temperature sensors in an upper part of the case, any temperature variation by 2° C. in three seconds detected by any one of the temperature sensors is determined to be abnormal, and thermal energy is caused to be discharged from surfaces of substrates on two sides of a flame by raising air flow rates of fans. Expansion of the flame to other substrates is thereby prevented.

摘要： A fuel injection controller of an internal combustion engine calculates a correction value for correcting a rotation fluctuation amount among cylinders of the engine during idling stabilization control. The controller calculates an average change in correction value over M number of changes in correction value for the cylinder. If it is determined that the average change is less than or equal to a threshold value a, it is determined that the correction value is stabilized. The correction value at that time is fixed as a learning value of a deviation amount of an injection characteristic among the cylinders. Thus, the fuel injection controller suitably achieves accurate learning of an inter-cylinder variation in the injection characteristic of the fuel injection valve and performing of the learning in a short time.

摘要： Brightness of a central area in a scene to be photographed and brightness of a peripheral area around the central area are measured, and the brightnesses of respective areas are outputted as first and second values. When the second value is larger than the first value, the first value is corrected by a value which has no relation with the respective measured values. Consequently, a proper controlling brightness value is provided for controlling the exposure.
