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 pump generates a gas flow within a measurement passage having an orifice. A differential pressure sensor detects a pressure difference between both ends of the orifice. Switching valves are disposed in the measurement passage to create a first concentration measurement state in which the measurement passage is opened at both ends thereof and the gas flowing through the measurement passage is the atmosphere, and a second concentration measurement state in which the measurement passage is in communication at both ends thereof with a canister and the gas flowing through the measurement passage is a fuel vapor-containing air-fuel mixture provided from the canister. An ECU calculates a fuel vapor concentration by based on a pressure difference detected in the first concentration measurement state and a pressure difference detected in the second concentration measurement state.
