发明名称 Apparatus and method for controlling intake air amount in engines that perform lean cumbustion
摘要 <p>An apparatus for controlling operation of an engine is disclosed. The apparatus includes a passage (20) for supplying air to the engine (1) and a fuel injection valve (11). The engine (1) burns air-fuel mixture to produce torque. A valve (23, 53) adjusts the quantity of air supplied to the engine. An ECU (30) actuates the valve (23, 53) based on the driving state of the engine (1). The ECU (30) feedback controls the air-fuel ratio by altering the position of the valve (23, 53) to prevent torque shocks caused by changes in the air supply. The feedback control employs two correction factors, the first of which is representative of the air-fuel ratio of the mixture, and the second of which is representative of an average deviation of the first factor from a stoichiometric air-fuel ratio value. The air-fuel ratio of the mixture is feedback controlled as a function of both correction factors. &lt;IMAGE&gt;</p>
