FUEL SUPPLY SYSTEM FOR INTERNAL COMBUSTION ENGINE

摘要

At the time of shifting a fuel property value associated with a first imaginary passage cell as a fuel property value associated with a second imaginary passage cell located on the downstream side thereof, the fuel property value associated with the second imaginary passage cell is corrected in a controller by computing a difference between the fuel property value associated with the first imaginary passage cell and the fuel property value associated with the second imaginary passage cell and multiplying the difference by a correction coefficient. A stoichiometric air/fuel ratio is computed in the controller based on the fuel property value, which is associated with a last one of the imaginary passage cells. Fuel injection of an injector is controlled by the controller based on a computed injection quantity of fuel, which is computed based on the stoichiometric air/fuel ratio.
