  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To perform a correction suitably with operating conditions of an engine without using specific additional parts, by comparing a basic fuel supply signal or load signal with a predetermined reference value and performing the correction for increase, decrease or cut-off of fuel in accordance with the above compared result.
CONSTITUTION: A revolution sensor 1 outputs a revolution signal S, corresponding to the rotational speed of an engine, and a load sensor 2 outputs a load signal S2 corresponding to the load condition of the engine. An arithmetic circuit 3 outputs a basic fuel feed amount signal S3 deriving from the revolution signal S1 and the load signal S2, and a correction circuit 4 calculates a fuel supply amount S4 by applying a correction, in accordance with various engine operation parameters fed from a water temperature sensor 5, to the basic signal S3. While a function generator 7 outputs a reference signal S5 having a relation of function with the revolution signal S1, and a comparator circuit 8 outputs a correction command signal S6 in accordance with the relation of level between the reference signal S5, and the load signal S2. Then the correction circuit 4 is controlled by said correction command signal S6 to perform the correction for increase, decrease or cut-off of the fuel.
