Title: Ignition-timing control for internal-combustion engine
Inventor: SHIKI KAZUHIRO
IPC: F02P5/152
Filed: 1984-01-27
Abstract: PURPOSE:To prevent the generation of knocking after a throttle valve is sharply opened, by delaying the ignition advance on the delay-angle side by the amount increased in accordance with the magnitude of the engine acceleration during a prescribed period from the time point when the throttle valve is opened from an idle position. CONSTITUTION:When a throttle valve 10 is opened from idle position in engine operation, an idle swithc in a throttle sensor 24 is turned OFF, and it is judged in a control circuit 20 that the number of times of ignition at the change time point is within N times of ignition ro not (the period up to the stabilization of the pressure in a suction pipe after the opening of the throttle valve). If the judgement is YES, that rapid accelerarion or not is judged on the basis of the variation rate of the opening degree of the throttle valve, and in case of rapid acceleration, the amount QR of delay angle is set to a prescribed value thetaA, and in case of slow acceleration, the amount thetaR of delay is set to a prescribed value thetaB (<thetaA). Then the idle ignition advance thetaIDL is compared with the ignitio advance obtained by correcting the fundamental ingnition advance read-out from a memroy, and if thetaIDL<theta, an ignitor 26 is controlled with the value obtained through the subtraction of thetaR from thetaIDL, as the final ignition advance.

Filed: 1990-01-24
Abstract: PURPOSE:To reduce an area a data control part occupies by generating the data control part based on inputted item information and inputted ruled line information by a definiendum editing part. CONSTITUTION:When the item information and the ruled line information are inputted, the definiendum editing part 21 generates the data control part 11 based on the inputted item information and the inputted ruled line information. Then, it edits the new definiendum from inputted data and read-in reference definiendum 2. In the data control part 11, line control tables 12, 13 are fixed, but cells 14, 15 are not fixed, but they are generated in response to input only when the input arises. Accordingly, the area cell groups 16, 17 occupy can be small. Thus, the area the data control part 11 occupies can be made smaller compared with a case the data is controlled by a traditional item/ruled line arranging state table.
