摘要： To change a fuel injection quantity to follow a throttle opening change in a low load region. A first calculator calculates a basic injection time using a throttle opening and an engine rotational speed. A second calculator calculates a basic injection time using an intake pipe negative pressure and the engine rotational speed. A selector selects the first calculator when the load is higher, and selects the second calculator when the load is lower. If the rate of change of the throttle opening is greater than a reference value, then a switcher sets the selector to select the first calculator. Thus, if the rate of increase of the throttle opening is greater than the reference value even when the load is low, the first calculator is selected.

摘要： In electronically controlling the opening of a throttle valve mounted in an intake system of an engine, the opening is controlled through a sliding mode control, based on a control amount including a control amount portion proportional to the switching function and a control amount portion corresponding to a nonlinear spring torque of a return spring urging said throttle valve in a direction to reduce the throttle valve opening. According to this constitution, the response characteristic of the control unit is maintained while restraining overshoot, enabling the opening to converge to the target opening promptly while sliding along a switching plane. Further, since said control amount includes the control amount portion corresponding to the nonlinear spring torque of the return spring, uncertainty element is reduced, to thereby perform a high response control.

摘要： The apparatus comprises two accelerator position sensors and two throttle position sensors, and when one out of said two accelerator position sensors or said two throttle position sensors fails to operate, a limitation is added to the increase in accelerator position for the output characteristics of the accelerator position sensor. Thereby, the vehicle is enabled to travel at a minimum speed necessary without excessively increasing the engine output. When one of the two throttle position sensors fails to operate, the fuel injection quantity may be set based on the detection value of the accelerator position, which enables the vehicle to be driven by approximately the desired speed without excessively increasing the engine output.

摘要： The present invention securely prevents the erroneous switching of the combustion mode to the stratified charge combustion, and avoids deterioration of the driving performance. In order to do so, apart from a software determination device inside a main CPU for performing the permission determination on the switching to the stratified charge combustion based on an input signal related to the engine drive condition, a hardware detection circuit (gate array) is equipped for performing the permission determination on the switching to the stratified charge combustion mode based on the input signal related to the engine drive condition. The main CPU is equipped with a combustion mode order device for finally ordering the stratified charge combustion by permitting the switching to the stratified charge combustion only when the two permission determinations both permit the switching to the stratified charge combustion. Further, a sub CPU is mounted which is equipped with a fail-safe device for based on the final permission determination from the main CPU and the permission determination from the hardware determination device, performing a fail-safe process when the two determinations are inconsistent.

摘要： The present invention aims at preventing such a situation that anyone of the divided injection amounts becomes less than a minimum compensation amount for a fuel injection valve, in case of conducting a two-step injection (weakly stratified combustion) in which a part of fuel is injected during intake stroke and the remaining fuel is injected during compression stroke. To this end, at the time of instructing to conduct the two-step injection, a whole injection amount TI is divided into: an injection amount TIH for homogeneous combustion to be injected during intake stroke, and an injection amount TIS for stratified combustion to be injected during compression stroke, based on a division ratio corresponding to a target air-fuel ratio. Further, each of the injection amounts TIH and TIS after division is compared with a minimum compensation amount MIN for the fuel injection valve. Based on the result of the comparison, the injection amount, which has a smaller division ratio, is set to be zero, and the injection amount, which has a larger division ratio, is set to be the whole injection amount TI, when either one of the injection amounts TIH and TIS is judged to be less than the minimum compensation amount MIN. Alternatively, the injection amount, which has the smaller division ratio, is set to be the minimum compensation amount MIN, and the injection amount, which has the larger division ratio, is set to be the remainder obtained by subtracting the minimum compensation amount MIN from the whole injection amount TI.

摘要： Cylinder to cylinder variation in developed cylinder torque is suppressed by correcting ignition timings for the individual cylinders or by correcting fuel injection amounts allocated to the individual cylinders. Amounts of correction to be made to the individual ignition timings or fuel injection amounts are determined as results of comparison of individual cylinder pressure averages with a multiple cylinder pressure average that is an average of the individual cylinder pressure averages.

摘要： Top dead center (TDC) is obtained by counting the number of unit angle signals from a reference angle signal for each cylinder, and combustion conditions of the engine are then detected based on fluctuations in the period of the top dead center. Here the unit angle signals occurring from after the reference angle signal until the TDC following the subsequent reference angle signal are counted, and the count number of the unit angle signals from after the reference angle signal until when the TDC is obtained, is modified based on a difference between the counted number and a reference value.

摘要： Apparatus and method for recognizing an absence or presence of a misfire in each of cylinders of a multi-cylinder internal combustion engine without influences of a mechanical deviation in a crank angle sensor and of a combustion state deviation between each of the cylinders. A period of each reference signal (REF) is generated from the crank angle sensor and a fuel combustion state deviation between each of the cylinders. The period of each reference signal (REF), which is generated from the crank angle sensor whenever an engine crankshaft has rotated through a predetermined crank angle expressed as 720.degree./n (n denotes a number of engine cylinders), is measured by a timer. A determination of the absence or presence of the misfire in each cylinder is made based on the measured period of the reference signal for each corresponding one of the cylinders. The measured period being corrected with either or both of first and second correction coefficients (KT.sub.i KKT.sub.i) derived by learning the corresponding first correction coefficient for the mechanical deviation and by learning the corresponding second correction coefficient for the combustion state deviation.
