Control unit of an internal combustion engine control unit utilizing a neural network to reduce deviations between exhaust gas constituents and predetermined values
First Claim
1. A control unit for an internal combustion engine for detecting an operation status of said internal combustion engine, comprisingdetection means for detecting at least one engine parameter including at least exhaust gas constituents indicating the operation status of said internal combustion engine;
- calculation means for calculating a supply fuel amount to said engine based on said operation status;
compare means for comparing said exhaust gas constituents with predetermined values; and
control means for correcting said supply fuel amount by using a neural network to render the deviation between said exhaust gas constituents and said predetermined values to zero.

Abstract
A control unit for an internal combustion engine that compensates for variations in injection valve flow rate characteristics by detecting an operation status of the engine and then using this status information to calculate a supply air amount or supply fuel amount in accordance with the detected status. Exhaust gas constituents are detected and then used to correct the calculated supply air or supply fuel amount. The control unit compares the exhaust gas constituents with predetermined values and then uses a neural network to control the supply air amount or supply fuel amount to make any deviation between the exhaust gas constituents and the predetermined value approach zero.
