  • Patent number: 7856307
    Abstract: A fuel injection control device for a multi-fuel engine includes a corrector and a reviewer. An alcohol concentration learning unit is provided to learn an alcohol concentration in an injected fuel based on an oxygen concentration detected in an exhaust gas. A fuel injection amount controller is provided to control a fuel injection amount based on a learning value corresponding to the oxygen concentration. The corrector is configured to reduce the fuel injection amount corresponding to the learning value for a predetermined time period when the learning value is higher than a threshold value when an engine is started. The reviewer is configured to review the learning value to provide a revised learning value based on the oxygen concentration while the corrector reduces the fuel injection amount. The fuel injection amount is controlled based on the revised learning value after the corrector reduces the fuel injection amount.

  • Patent number: 7778764
    Abstract: A fuel injection control apparatus for a multi-fuel engine can optimize a fuel injection quantity, using only one basic injection map, irrespective of alcohol concentration of a fuel. An E-concentration determining apparatus determines alcohol concentration of a fuel, based on a measured oxygen amount in exhaust. Basic injection quantities are stored in a basic injection map. E-concentration coefficients are stored in an E-concentration coefficient table for a plurality of alcohol concentrations in the fuel. A basic injection quantity, corresponding to a current rotary engine speed and a throttle opening, is selected from the basic injection map. A concentration coefficient, corresponding to the alcohol concentration and the basic injection quantity, is selected from the E-concentration coefficient table. A fuel injection quantity calculator determines an applied fuel injection quantity by multiplying the basic injection quantity by the concentration coefficient.

  • Patent number: 7528708
    Abstract: A variation detection device has a processor, an AD converter converting a signal voltage output from a sensor to generate an AD converted value and outputting the AD converted value to the processor, a temperature sensor detecting a temperature of the sensor, and a memory storing a table which indicates a relationship between temperatures and initial values. When receiving the AD converted value, the processor identifies a temperature of the sensor based on an output of the temperature sensor, reads out an initial value corresponding to the identified temperature from the table, and calculates a variation between the initial value and the AD converted value.
