摘要： A part of the air flowing through a main passage flows into a by-pass passage. A flow rate detector is provided in the by-pass passage. An outlet of the by-pass passage is opened at the narrowest portion of a venturi structure provided in the main passage. The by-pass passage is in communication with a pressure-accumulating chamber, which is in communication with the main passage at the portion thereof which is on the downstream side of the venturi structure. The pressure of the air flowing backward from the engine is stored in the pressure-accumulating chamber. The pressure in the pressure-accumulating chamber serves as a passage resistance with respect to the flow of the air in the by-pass passage. Accordingly, the flow rate detector permits determining the flow rate of the air, which does not contain a component representative of a backward flow of the air.

摘要： In order to take into consideration the different response by a hot wire sensor to changes in temperature of air as opposed to changes in temperature of fuel, the circuit configuration of a hot wire sensor for fuel flow detection differs from that for air flow detection in that an additional resistance is connected in series with the flow measuring resistance in the bridge circuit of the fuel flow detector, while the additional resistance is connected in series with the temperature compensating resistance in the bridge circuit of the air flow detector.

摘要： A heat-type flow sensor is provided on the upstream side of a Venturi portion formed in an air-intake path and in an air bypass communicating with the Venturi portion. An electromagnetic device is provided to control the amount of air flowing in the air bypass so that the output of the heat-type flow sensor converges to a set level. This electromagnetic device drives a fuel-scaling valve to scale fuel in accordance with the change of the amount of air supplied to the engine, and this scaled fuel is continuously injected into the air-intake path.

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.
