FUEL INJECTION AND IGNITION TIMING CONTROLLER FOR INTERNAL-COMBUSTION ENGINE

摘要

PURPOSE:To improve the acceleration response by deciding to be acceleration if the throttle valve opening variation rate has exceeded over predetermined level then correcting the intake air pressure data or the intake air flow data on the basis of said variation rate and operating fuel injection on the basis of the corrected data. CONSTITUTION:Under engine operation, control circuit 10 will operate throttle valve opening variation rate DELTATA on the basis of the current and previous levels of throttle valve opening data produced through a throttle sensor 6 and decide whether said level is higher than predetermined level. If the answer is YES, intake air pressure data PM produced through a pressure sensor 4 is incremented in accordance to said variation rate DELTATA. Then basic injection TP is operated on the basis of the corrected intake air pressure data PM and the rotary speed data Ne produced through a crank angle sensor 9 to perform necessary corrective operation in accordance to such as water temperature thus to operate the final injection TAU and to control a fuel injection valve 11 on the basis of the operational results.
