摘要： An air-fuel ratio control system for an internal combustion engine includes a LAF sensor and an O2 sensor arranged in an exhaust pipe at respective locations upstream and downstream of a catalytic converter. A desired air-fuel ratio coefficient used in calculating an amount of fuel supplied to the engine is calculated based on operating conditions of the engine, and corrected based on output from the O2 sensor. The air-fuel ratio of a mixture supplied to the engine is feedback-controlled to a stoichiometric air-fuel ratio based on the corrected desired air-fuel ratio coefficient. When the output from the O2 sensor falls within a predetermined range, the desired air-fuel ratio coefficient is not corrected, but held at an immediately preceding value thereof.

The amount of fuel to be supplied to the engine is corrected based on the amount of fuel adhering to the inner wall surface of the intake passage and the amount of fuel carried off the fuel adhering to the inner wall surface of the intake passage to determine a corrected amount of fuel supplied to the engine. The corrected amount of fuel to be supplied to the engine is injected into the intake passage. The timing of the fuel injection is controlled based on the adherent fuel-determining parameters.

A volume of the gas purged over a predetermined time period is calculated based on the output from the flowmeter. A parameter indicative of dynamic characteristics of the gas is calculated based on operating conditions of the engine. An amount of air contained in the purged gas drawn into a combustion chamber of the engine is calculated at least based on the concentration of evaporative fuel, the volume of the purged gas, and the parameter indicative of dynamic characteristics of the gas.

摘要： An air-fuel ratio of an air-fuel mixture produced by fuel injected from a first injector into an intake port (or into a combustion chamber) is set in a range of 28 to 38. Therefore, when the temperature and pressure rise with a first combustion started by spark-ignition around a spark plug to the fuel injected from a second injector into the combustion chamber, the timing of starting a second compressive hypergolic ignition is optimized to provide a stable combustion state free of knocking and misfire.
