    摘要: An exhaust purifying apparatus for an internal combustion engine includes an exhaust purifying mechanism, a fuel adding device, an electronic control device. The exhaust purifying mechanism is located in an exhaust passage and traps particulate matter. The fuel adding device adds fuel to exhaust gas that passes through the mechanism. The electronic control device detects a pressure difference between a section upstream and a section downstream of the exhaust purifying mechanism. While the fuel adding device is adding fuel to exhaust gas, the electronic control device compares the pressure difference that is detected at a predetermined point in time with the pressure difference reference value. When the pressure difference exceeds the pressure difference reference value, the electronic control device sets the manner of adding fuel to intermittent fuel addition. As a result, the exhaust purifying apparatus decreases the amount of particulate matter that remains in the exhaust purifying mechanism.

    摘要: A three-way catalyst device having an oxygen absorbing/releasing capability is provided in an exhaust passage of an internal combustion engine. An upstream-side air-fuel ratio sensor that outputs an output value in accordance with the air-fuel ratio of exhaust gas is provided in the exhaust passage upstream of the three-way catalyst device. A downstream-side air-fuel ratio sensor that outputs an output value in accordance with the air-fuel ratio of exhaust gas is provided in the exhaust passage downstream of the three-way catalyst device. A comparison value is calculated by comparing the length of an output locus formed by output values of the upstream-side air-fuel ratio sensor and the length of an output locus formed by output values of the downstream-side air-fuel ratio sensor. By comparing the comparison value with a predetermined criterion, it is determined whether the three-way catalyst device has deteriorated. At least one of the downstream-side air-fuel ratio sensor output value and the predetermined criterion is corrected in accordance with the downstream-side air-fuel ratio sensor output value. Therefore, deterioration of the three-way catalyst device can be determined with high precision.

    摘要: A compressed natural gas-fueled automotive vehicle is disclosed in which the fail-safe control operation is performed thereby to secure the safety of the vehicle when the gas pressure drops. If the remaining amount of the gas is very small, an engine misfire occurs. If the catalyst temperature is high, the uncombusted gas begins to burn on contact with the high-temperature catalyst in the catalyst unit. In view of this, upon detection of both a gas pressure drop and the vehicle moving condition or upon detection of both a gas pressure drop and an increased catalyst temperature, the fuel supply is stopped or the vehicle speed is reduced to thereby reduce the catalyst temperature. As a result, uncombusted gas is not burnt in the catalyst unit and the catalyst unit is prevented from being destroyed.

    摘要: In an air-fuel ratio feedback control system including at least one air-fuel ratio sensor downstream of or within a catalyst converter provided in an exhaust gas passage, an actual air-fuel ratio is controlled in accordance with the output of the air-fuel ratio sensor, which is supplied to a pull-up type input circuit. After the output of the pull-up type input circuit becomes lower than an activation control level, the determination of whether or not the air-fuel ratio sensor is activated is carried out by determining whether or not the output of the pull-up type input circuit is within an active region, depending on the base air-fuel ratio of the engine.

    摘要: In a color imaging apparatus having a single chip solid state state sensor and an n color filter matrix, n color signals are used by an operation circuit in a first signal processing mode to generate chrominance signals and a luminance signal. When one of the n color signals reaches a saturation level, the operation circuit utilizes the remaining n-1 color signals. When a second color signal reaches the saturation level, a compensation signal is generated from a particular non-saturated color signal and the operation circuit utilizes the remaining n-2 non-saturated signals, including the particular non-saturated signal, and the compensation signal to produce the chrominance signals and the luminance signal. Compensation signals are generated from the particular signal until the particular color signal saturates. The particular color signal saturates last.

    摘要: A method for controlling an internal combustion engine equipped with a fuel injection valve fitted to its intake manifold. Repeatedly values are determined of a first quantity approximately representing the proper amount of fuel to be injected, at least partly based upon signals from an air flow meter and a revolution sensor. Simultaneously, repeatedly the current value of a second quantity approximately representing the actual amount of fuel to be injected is determined, at least partly based upon signals from the air flow meter and the revolution sensor, an average value of all the successive instances of the value of the first quantity in some time interval up to the present is determined, and the current value of the first quantity is compared with this average. It is determined whether or not the engine is being accelerated, according to whether this current value is less than this average value; and if the engine is being accelerated and is also not fully warmed up, then the current value of the second quantity is increased somewhat, so as to produce an adjusted value corresponding to proper fuel amount. Optionally the adjusted value may be further adjusted. At proper points in the operational cycle of the engine, the fuel injection valve is opened for a period which allows approximately the fuel amount represented by the adjusted value to be injected. A device is also explained, incorporating an electronic computer, which practices this method.

    摘要: A compensation value computing method for an electronic fuel injection controlled engine according to this invention measures an operating parameter for detecting the idling, low-load and high-load running conditions of the engine. First, second and third memory locations are provided corresponding, respectively, to these running conditions of the engine to compute feedback air-fuel ratios on the basis of feedback signals from an air-fuel ratio sensor. Values in the memory are compensated corresponding to the detected running conditions of the engine on the basis of the deviation of a feedback air-fuel ratio from the base air-fuel ratio. When the values in at least two memory locations differ from the base value by not less than a predetermined value, the altimetric compensation value is adjusted and when the difference between values in the first and third memories is larger than that between values in the second and third memories, the output compensation value of an air flow meter for detecting intake air flow is adjusted.
