摘要： A fuel supply control control method for an internal combustion engine, which is adapted to determine a quantity of fuel for supply to the engine by multiplying a basic value of the quantity of fuel determined as a function of at least one operating parameter of the engine, by correction coefficients dependent upon operating conditions of the engine, and adding to the basic value correction variables dependent upon operating conditions of the engine, and to supply the determined quantity of fuel to the engine. Values of predetermined one of the above correction coefficients and predetermined one of the above correction variables are determined, which correspond to a set desired value of output voltage of a single voltage creating means. The basic value of the quantity of fuel is corrected by the determined values of the predetermined one correction coefficient and the predetermined one correction variable through multiplication and addition, respectively, to determine the quantity of fuel. Preferably, a plurality of pairs of a value of the predetermined one correction coefficient and a value of the predetermined one correction variable are stored beforehand, and one pair is selected from the plurality of pairs, which corresponds to the set desired value of output voltage of the voltage creating means. Further, preferably, in adjacent ones of the plurality of pairs, either the predetermined one correction coefficient of the predetermined one correction variable is set at the same value.

摘要： A variable frequency dividing circuit according to this invention switches a frequency division ratio immediately after a neew frequency division ratio has been input, and then performs a frequency dividing operation without discarding already counted values. This frequency dividing circuit generates an error signal if a newly input frequency division ratio differs from the previous frequency division ratio and the already counted value is larger than the new frequency division ratio. Furthermore, the frequency dividing circuit performs forcibly a frequency division completion processing according to the consecutively input frequency signal.

摘要： Fuel injection is started through a first one of fuel injection valves, and a time counter counts a period of time elapsed from the start of fuel injection through the first one valve. Fuel injection is started through a second one of the fuel injection valves when a predetermined period of time elapses after the start of fuel injection through the first one valve. The fuel injection through the first one valve is terminated in response to completion of counting of the time counter, and the time counter is restarted to count a difference between a desired fuel injection period of time for the first one valve and a desired fuel injection period of time for the second one valve. The fuel injection through the second one valve is terminated in response to completion of counting of the restarted time counter.

摘要： An engine control system includes a pulse generator for generating a synchronous pulse signal synchronously with the speed of rotation of an engine, a timer for generating a timer pulse signal of a constant period, and a microcomputer having an interrupt input terminal for receiving the pulse signals as interrupt signals and operable to start processing operations in response to the interrupt signals, so that a number of controlled objects of the engine can be controlled on the basis of data indicative of operating conditions of the engine. Data is processed in response to an interrupt caused by the synchronous pulse signal to control a first-group controlled object of the number of controlled objects and setting a flag to request processing of data items related to the first-group controlled object. Data is then processed in response to an interrupt caused by the timer pulse signal to control a second-group controlled object of the number of controlled objects and setting a flag to request processing of a data item related to the second-group controlled object. In the absence of the interrupts, a plurality of predetermined data items and the data items requested to be processed by the flags are processed.
