摘要： An internal combustion engine control apparatus has a digital arithmetic unit to which signals are inputted from a plurality of detectors such as detectors for detecting an operational state of the engine and air fuel ratio detector and controls a fuel air ratio and ignition timing according to output signals from the arithmetic unit. The apparatus comprises by a misfire detector for detecting a misfiring state of the engine, NOx concentration detector and a controller for controlling the fuel air ratio and the ignition timing so as to fall within a tolerable stable combustion range defined by a detected misfire boundary and a detected NOx limit. The misfiring state and/or NOx concentration can be detected through detection of temperature change in the combustion chamber by a detector. The detector comprises a black body disposed in the combustion chamber and a fused silica cable mounting the black body.
