    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.

    摘要: A sensor that detects a fuel property of a mixed fuel of a biofuel and a hydrocarbon fuel includes: a light emitting device that emits light with a wavelength of 250 nm to 400 nm onto the mixed fuel; and a light receiving device that receives light emitted by the mixed fuel under the effect of light from the light emitting device and generates an output corresponding to the received light. When the fuel property is determined, in a case where the mixed fuel is irradiated by light with a predetermined wavelength generated due to voltage application to the light emitting device, the light emitted by the mixed fuel is detected by the light receiving device. The fuel property of the mixed fuel is detected according to the detected light.

    摘要: An ECU computes a transit time from a time when the fuel vapor passes the purge valve right after the purge valve is opened until a time when the fuel vapor reaches a vicinity of the fuel injector. Further more, the ECU computes a fuel vapor concentration at the vicinity of the fuel injector after the transit time has elapsed based on a first-order lag curve which is defined by a maximum variation of the fuel vapor concentration and a time constant. Correcting the fuel injection quantity according to the fuel vapor concentration at the vicinity of the injector restricts a disturbance of air-fuel ratio at a time of starting purge process.

    摘要: A fuel nature measuring device for measuring the nature of fuel stored in a fuel tank includes a measurement passage, a gas flow generator, a pressure detector, an concentration operator, a temperature detector, and a volatility calculator. The measurement passage has an orifice. The gas flow generator generates gas flow in the measurement passage. The pressure detector detects a differential pressure between opposite ends of the orifice. The concentration operator determines a concentration of evaporated fuel in the fuel tank based on the differential pressure detected when the opposite ends of the measurement passage communicate with the fuel tank and the fuel flows in the measurement passage. The temperature detector determines a temperature of the fuel in the fuel tank. The volatility calculator calculates a volatility of the fuel in the fuel tank based on the concentration of the evaporated fuel and the temperature of the fuel in the tank.

    摘要: A fuel vapor processing apparatus includes a canister, a purge passage, a detection passage including an atmosphere passage and a restrictor, a passage changing valve for changing the connection passage of the detection passage between the purge passage and the atmosphere passage, a pump connecting with the detection passage on the opposite side of the passage changing valve across the restrictor, a pressure sensor for detecting a pressure between the restrictor and the pump, and an ECU for computing the concentration of fuel vapor. When the passage changing valve causes the purge passage to connect with the detection passage and the pump reduces pressure in the detection passage to pass the air-fuel mixture through the restrictor, the pressure sensor detects the pressure during a detection period of time that elapses after the air-fuel mixture passes through the restrictor until the air-fuel mixture reaches the pump.
