Electronic apparatus for feed control of air-gasoline mixture in internal combustion engines |
摘要 |
An apparatus for controlling the air-gasoline mixture supplied to an internal combustion engine is disclosed. A microcomputer receives a plurality of input signals representative of characteristic magnitudes of engine operation and of the air-gasoline ratio and controls the operation of a metering device as a function of the signals. The microcomputer is programmed with a predetermined feed law to provide predetermined engine performances. The feed law is stored in the form of numerical values, each of which correspond to the metering amount of the metering device which amount has been predetermined to result in the optimum strength of the air-gasoline mixture. The microcomputer is adapted to correct the numerical values in accordance with the difference between the programmed numerical value corresponding to the stoichiometrical air-gasoline ratio and that value which makes it possible to effectively obtain the stoichiometrical ratio under the actual engine operating conditions.
