A drowsiness sign notification system applied to a vehicle includes a driver monitor and a controller. The driver monitor detects a driver state being a state of a driver of the vehicle. The controller executes a drowsiness sign determination process that determines whether or not the driver shows a drowsiness sign based on the driver state. When it is determined that the driver shows the drowsiness sign and an activation condition is satisfied, the controller executes rest area informing process that informs the driver of a rest area. The activation condition of the rest area informing process is set from a viewpoint of a relationship between a location of the rest area and a target route of the vehicle, or an expected time required for the vehicle to reach the rest area.

The present invention is a method of solidifying sulfur component being the cause of &ldquo;SOx poisoning&rdquo; by use of a sulfur solidifier. The solidifier includes a metal element having a function of oxidizing the sulfur component and a basic metal element. And the solidifier solidifies sulfur component before exhaust gas flows into an NOx-occluding reduction-type exhaust purifying catalyst located on an exhaust path. Since the foregoing sulfur solidifier includes the above metal element and the basic metal element, it can effectively solidify the sulfur component which are the cause of the SOx poisoning, and ensure improvement in purification performance.

According to the present invention, there is provided a device for diagnosing malfunction in a fuel tank. The fuel tank has a separator wall therein which separates an interior of the fuel tank into a fuel chamber and an air chamber. The separator wall is deformable according to an amount of fuel in the fuel chamber. The device comprises a device for detecting a change of at least one of a position of the separator wall, the pressure in the tank and the concentration of fuel vapor in the tank, and a device for diagnosing malfunction of the separator wall on the basis of the change to diagnose that the separator wall has malfunction when the change differs from a predetermined regular change.

Device for diagnosing malfunction in a fuel tank

According to the present invention, there is provided a fuel reserving device for reserving fuel therein. The device comprises a fuel tank for reserving fuel therein, and a fuel vapor tank for reserving fuel vapor therein. The fuel vapor is fed from said fuel tank to said fuel vapor tank and returned from said fuel vapor tank to said fuel tank. The fuel vapor is not returned from said fuel vapor tank to said fuel tank when a pressure in said fuel tank would be higher than a predetermined pressure if the fuel vapor was returned from said fuel vapor tank to said fuel tank.

Fuel reserving device

A failure diagnosing apparatus makes an judgment as to whether or not a failure occurs in an evaporated fuel processing apparatus in which an evaporated fuel within a fuel reservoir is adsorbed by an activated charcoal within a canister and the evaporated fuel adsorbed by the activated charcoal is purged to an intake system of an internal combustion engine under a certain operational condition. An atmospheric air is introduced into the fuel reservoir when the fuel is supplied to the fuel reservoir. Accordingly, there is a fear that a misdiagnosis is performed if the failure diagnosis is performed during fuel supply. Accordingly, when the internal combustion engine is in operation and in fuel supply condition, the failure judgement process by the failure diagnosing apparatus is forbidden.

Three-way VSV switches a passage in communication with pressure sensor either to the atmosphere or to three-way VSV. The three-way VSV is provided in bypass passage connecting fuel tank with canister to switch the path to the fuel tank side or to the canister side with respect to tank internal-pressure control valve. As properly switching the three-way VSVs, the pressure sensor can detect both the pressure in the evaporation purge system and the atmospheric pressure. Upon diagnosis of defect a difference is calculated between the in-system pressure and the atmospheric pressure detected, which cancels out the dispersion or the like upon production of the pressure sensor, thus enabling to detect an accurate pressure change.

A fuel storing device for an automobile, having a flexible separator means disposed in a fuel storage container for separating the inside of the fuel storage container into a fuel storage portion and a space portion, comprises a fuel suction pipe inlet opening keeping means for keeping the opening for withdrawing fuel open in said fuel storage portion. The fuel suction pipe inlet opening keeping means prevents the inlet opening of the fuel suction pipe from being covered, and thereby all of the fuel can be sucked while any fuel is left in the device.

A fuel pressure control apparatus includes a valve for controlling an internal pressure of a fuel tank, the valve including a valving member, a valve seat, and an actuating member for pressing the valving member on the valve seat under a set pressure; and a pressure adjusting part for adjusting the set pressure of the actuating member of the valve to a first set pressure when an engine is operating, the first set pressure being higher than an atmospheric pressure and allowing the internal pressure of the fuel tank to be in equilibrium with the first set pressure, and for adjusting the set pressure of the actuating member to a second set pressure when the engine stops operating, the second set pressure being higher than the first set pressure, thus allowing the internal pressure of the fuel tank to be increased, when the engine stops operating, to a pressure higher than the first set pressure.

An evaporation loss control device provided with a polymer chamber filled with polymer absorbent, a charcoal chamber filled with charcoal, introduction and purging pipes for connecting the polymer chamber with a fuel tank and an engine intake passage, respectively, an air pipe for ventilation connected to the charcoal chamber, and a vapor passage, which has various forms. For example, the vapor passage may be formed in spiral to encircle the polymer chamber, or provided between the polymer and charcoal chambers, thus allowing the evaporated fuel to pass therethrough. The vapor passage is constructed to prevent the evaporated fuel trapped by the polymer absorbent from flowing into the charcoal chamber, and also to prevent the liquid fuel from being absorbed by the charcoal.

Evaporation loss control device

A fuel tank including a tank body, a fuel supply pipe mounted on the tank body, a first canister connected to the tank body through a first fuel vapor passage provided with a change-over control valve therein, and a second canister connected to the tank body through a second fuel vapor passage provided with a check valve therein. The change-over control valve is opened during supply of fuel through the fuel supply pipe and the check valve is opened when the pressure within the tank body exceeds a predetermined value. A first vapor leading opening of the first fuel vapor passage for the first canister is positioned lower than a second vapor leading opening of the second fuel vapor passage for the second canister.

Fuel tank

A fuel tank comprising a fuel inlet pipe. A fuel pump nozzle is inserted into the fuel inlet pipe. A throat portion having a venturi shaped cross-section is arranged in the fuel inlet pipe between the interior space of the fuel tank and the tip of the fuel pump nozzle inserted into the fuel inlet port. Fuel spouted from the fuel pump nozzle passes through the entire cross-section of the throat portion.

Fuel tank having an inlet pipe with a guide and venturi restriction

A fuel tank including a tank body, a fuel supply pipe mounted on the tank body, and a canister connected to the tank body. The fuel supply pipe is provided with a closing valve therein, the canister is connected to the tank body through a first fuel vapor passage having a change-over control valve. The fuel injection pipe is further communicated with the tank body through a second fuel vapor passage. The change-over valve is interlocked to the closing valve so that the change-over valve opens the first fuel vapor passage along with opening of the closing valve when a fuel feed nozzle is inserted into the fuel injection pipe.
