FUEL CONTROLLER FOR INTERNAL COMBUSTION ENGINE

摘要

PURPOSE:To correctly carry out the fuel control by installing a correcting means for correcting the output of an AN detecting means for detecting the intake quantity per prescribed crank angle by the correction coefficient for the detection output of an intake quantity sensor. CONSTITUTION:A Karman's vortex type intake quantity sensor 13 detects the intake air quantity of an internal combustion engine 1. An AN detecting means 20 detects the A/N from the outputs of the intake quantity sensor 13 and a crank angle sensor 17. The AN calculating means 21 calculates the number of pulses corresponding to the output of the intake quantity sensor 13 correspond ing to the intake air quantity. A control means 22 controls the driving time of an injector 14 and controls the quantity of fuel supplied into the internal combustion engine 1. Since the output of the A/N detecting means 20 is corrected by the correction coefficient for correcting the output of the intake quantity sensor, the correct A/N can be obtained, and the fuel control on the basis of A/N can be correctly carried out.
