摘要： In order to cause a computer to execute integral calculation of an integrand, to thereby calculate a value of a second variable used at each calculation time point, the integrand being defined by: a first variable to which a value is given at all calculation time points; and the second variable to which only an initial value is given, the following processing is executed. First, a partial derivative which is obtained by partially differentiating the integrand for the second variable is read out from a storage device. At each calculation time point, the initial value or a value of the second variable calculated at a last calculation time point and a value of the first variable given at a current calculation time point are substituted into each of the integrand and the partial derivative, to thereby calculate a value of the integrand and a value of the partial derivative at the current calculation time point. After this, a value of the second variable used at a next calculation time point is calculated by using an exponential function in which: the calculated value of the integrand is used as an initial value; and a value obtained by multiplying the value of the integrand by the value of the partial derivative is used as a gradient. Accordingly, it becomes possible to solve a differential equation of a distributed parameter system with a reduced amount of calculation.

摘要： An apparatus for measuring an intake air flow of an internal combustion engine, wherein presence of a backflow is determined from a waveform of the electric signal of flow detecting unit. If a backflow is present, a kurtosis is calculated. A backflow ratio is calculated based on the relation obtained from the kurtosis and the backflow ratio. The mass of the flow obtained by converting electric signals from the flow detecting unit into flows are integrated or averaged. Then, the integrated value or the average value is compensated by the backflow ratio, and accumulate mass of the air flow is calculated.

摘要： When a fuel cut command is issued, a time required for a crankshaft of each cylinder to rotate through a certain angle is stored in one memory per cylinder. In a stage of engine production, a combustion variation per cylinder is stored in another memory.

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.
