摘要： A fuel vapor leak detecting apparatus, includes: a valve which is in a vapor purge system including a canister that is communicated with a fuel tank and an internal combustion engine, and which controllably closes the vapor purge system; a pressurizing section which introduces atmospheric air into the vapor purge system to pressurize the vapor purge system; and an internal-pressure measuring section which detects an internal pressure of the vapor purge system. The pressurizing section supplies the air for a predetermined time in a state where the vapor purge system is closed. When the internal pressure measured by the internal-pressure measuring section at the air supply is equal to or lower than a preset criterion pressure, it is judged that leak occurs.

摘要： An apparatus for detecting fuel-vapor gas leaks that includes a jet pump (8) that introduces outside air into and pressurizes a vapor purge system including a fuel tank (1) by gasoline flow from a fuel pump (2); an internal pressure sensor (14) for measuring vapor purge system internal pressure, an open/close controllable reference orifice (21) that causes leakage through a reference leak hole; and a storage device for storing as an initial curve pressure changes during pressurization by the jet pump (8) for a predetermined time period, with the reference orifice (21) alone opened. The device can accurately detect leakage even while an internal combustion engine is running because it judges leak presence/absence by comparing a time series in a pressure curve obtained by jet pump (8) pressurization over the predetermined time period while idling with the vapor purge system completely shut-off, with a time series in the initial curve.

摘要： The detection device provides with an optical fiber composed of a core, a clad and a fiber jacket. A grating is applied to the core, and the fiber jacket located at the portion to which the grating is applied is removed so that the clad is in contact with a fuel fed to an injector of a vehicle. The detection device also provides with a light source for incidence of a light in a range of clad mode wavelength to the optical fiber, and a light-sensitive part for detecting an intensity of the light transmitting through the region to which the grating is applied. The optical fiber, light source and light-sensitive part are held in a conduit disposed in a fuel tank or between a fuel pump and the injector of the vehicle.

摘要： A fuel pump module is formed in such a manner that a sensor unit having a semiconductor diaphragm is provided in a recess of a bracket having a flange portion holding a fuel pump through a high-pressure filter. The recess is closed by a sensor cap having a lead-in pipe to thereby form an tank internal-pressure sensor. While internal pressure of a fuel tank is led into the tank internal-pressure sensor through an internal pressure lead-in pipe, atmospheric pressure is led into the tank internal-pressure sensor through an external air intake hole provided in the lead-in pipe. Thus, internal pressure of the fuel tank is detected.
