摘要： An air feed ratio controlling apparatus can include a predictor for predicting an air fuel ratio on the downstream side of a catalyst calculates a predicted air fuel ratio at least based on an actual air fuel ratio from an oxygen sensor and a history of a first correction coefficient. The air fuel ratio controlling apparatus can also include an adaptive model corrector which determines the deviation between the actual air fuel ratio and the predicted air fuel ratio as a prediction error ERPRE, and superposes a second correction coefficient on the first correction coefficient so that the prediction error may be reduced to zero.

摘要： A fuel injection control device of an internal combustion engine capable of using multiple kinds of fuel includes an ECU with a ROM for storing multiple reference fuel injection quantity maps corresponding to mixture concentrations of the multiple kinds of fuels. A control program of the CPU stores which of the multiple reference fuel injection quantity map is used out of the maps in an EEP-ROM, performs starting control of an engine using the reference fuel injection quantity map which is used immediately before stopping previous time at the time of initiating the starting based on the stored maps and, at the same time, performs the starting control by gradually increasing the fuel injection quantity until the starting of an engine is finished. As a result, control of fuel supply is optimized in response to mixing different kinds of fuels, and the engine starting time is shortened.

摘要： A vehicular fuel tank fuel filler orifice device that is provided with a fuel filler orifice in an upper wall of a vehicular fuel tank that stores ethanol fuel for an engine and a fuel filler guide tube extending from the fuel filler orifice to the interior of the fuel tank. A flame arrestor made of a metal mesh with a larger diameter than that of the fuel filler guide tube is mounted on the fuel filler guide tube. The flame arrestor covers a lower opening of the fuel filler guide tube for allowing a flow of the fuel but preventing the entrance of a flame. Using a flame arrestor, not only prevents a flame from entering a fuel tank from a fuel filler orifice but also smoothly carries out an exchange of fuel and air in the flame arrestor when filling with fuel, thus speeding the filling with fuel.
