JPH0487995A - Oil feeder with judging faculty of oil kinds - Google Patents

Abstract

PURPOSE:To obviate the necessity of a sampling mechanism for guiding vaper to a gas senser and to prevent mis-judging of oil kinds, by providing a sender of fuel oil data equipped at the oil feed cap, on a placing base. CONSTITUTION:A pacing base 9 of an oil feed cap is formed as a recess at a part of the upper face of a part of an oil feeder box 10. A senser 1 equipped near the placing base 9 of the oil cap outputs signals to a controller 7. The oil feed cap is removed from the fuel oil tank of an automobile to feed oil and placed on the placing base 9 previously specified. In this way, since this senser 11 outputs some signals regardless of kinds of oil, the controller 9 detects that the oil feeding cap is removed and placed on the placing base 9. In this way, oil kinds are read in accordance with the data of an oil kind indicator F of the oil feed cap A by the actuation of senser 11 and compared with previously registered oil kinds.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention automatically determines the type of fuel oil in the fuel tank of an automobile, and when the type matches the oil type registered in the refueling nozzle, refueling is started. This invention relates to a refueling device that allows

(Prior art) There are two types of automobiles: those that use gasoline and those that use diesel oil, and when different fuels are used, the engine may suffer serious damage (this is not the case). .

For this reason, before refueling, the vapor in the car's fuel tank is drawn into a gas sensor to measure the vapor concentration, and based on this result, the type of oil in the fuel tank is determined and matches the type of oil in the refueling nozzle. A refueling device has been proposed that allows refueling only when the
Publication No.).

(Problem to be solved by the invention) According to such a device, the type of fuel oil in the automobile fuel tank can be automatically determined, and mistakes such as injecting a different type of fuel oil can be avoided. can be prevented.

However, there are problems with the complexity of the device as it requires a sampling mechanism to guide the vapor inside the automobile fuel tank, and if there is fuel oil remaining in the nozzle pipe, the fuel oil may be removed during the next refueling. There is an inconvenience that it may drip into the mouth and cause a mistake in determining the type of oil.

The present invention was made in view of these problems, and its purpose is to eliminate the need for a sampling mechanism for guiding vapor to a gas sensor, and to prevent mistakes in oil type determination. An object of the present invention is to provide a novel oil supply device with an oil type determination function.

(Means for Solving the Problems) In order to solve such problems, in the present invention, a fuel filler cap mounting portion is provided on the main body of the fuel supply device or a stand placed therein, and the fuel filler cap is A sensor for reading the fuel oil data provided in the fuel oil is provided in the @ storage section, and the oil type is determined based on the signal from the sensor.

(Operation of the Invention) When the fuel filler fitting is removed from the fuel tank of a car in order to refuel, and the fuel filler cap is placed on the fuel filler cap mounting portion of the fuel filler body or a stand placed near it, a sensor is installed on the fuel filler cap. The system reads the data on the oil type display member, determines whether this data is the same as the pre-registered oil type, and permits refueling only if they match.

(Example) The details of the present invention will be described below based on illustrated examples.

FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure is a refueling pump. A flow meter 2 is connected to the discharge port of this pump, and refueling is supplied via a refueling hose 4. It communicates with nozzle 5. The flowmeter 2 is equipped with a flow rate pulse generator 6, and a control device 7 converts the flow rate pulses outputted from the flow rate pulse generator 6 into a refueling amount and outputs the same to a display device 8.

Reference numeral 9 denotes a fuel filler cap mounting portion, which is formed in a part of the upper surface of the fuel supply device housing 10 as a recess large enough to accommodate the fuel filler cap.

Reference numeral 11 denotes a sensor provided close to the fuel filler cap mounting portion 9, and outputs future signals to the control device 7.

FIG. 2 shows an example of a fuel filler cap of an automobile to which the above-mentioned fuel filler device can be applied.
An optically or magnetically readable oil type display member F is attached to the.

FIG. 3 shows a first embodiment of the above-mentioned sensor, and reference numeral 12 in the figure is an optical sensor disposed so as to face the window 9a of the fuel filler cap mounting portion 9. 16 is designed to receive the reflected light from the light emitting element 15 so as to detect the character data of the oil type display member F attached to the surface or the color of each oil type. This is a data processing device that outputs oil type data using signals.

FIG. 4 shows a second embodiment of the sensor 11 described above, and reference numeral 7 in the figure is a magnetic sensor made of a Hall element or the like arranged to face the fuel filler cap mounting portion 9. , the fuel filler cap A (attached to the oil filler cap A) on the mounting portion 9 reads magnetic data and polarity. 18 outputs oil type data based on the signal from the magnetic sensor 17. It is a data processing device that performs

According to these sensors, the type of oil can be determined reliably by displaying the type of oil using a bar code or color, or by attaching a display member representing the polarity of a magnet to the fuel filler cap.

Next, the operation of the apparatus configured as described above will be explained based on the flowchart shown in FIG.

To refuel, a fuel filler cap is removed from a fuel tank of a car and placed on a predetermined fuel filler cap mounting portion 9 of a mounting stand. As a result, the sensor 11 outputs a signal regardless of the type of oil, so the control device 9 detects that the fuel filler cap has been removed and that it has been poured onto the mounting portion 9 (Step I). Thereby, the sensor 11 is activated to read the oil type based on the data on the oil type display member F of the fuel filler cap A, and compare it with the oil type registered in advance (step
Ha, ho). As a result of the comparison, if the oil types match, a message indicating that the oil types match will be displayed.
When the nozzle is removed from the nozzle hook and the nozzle switch 19 is turned on (Step 1), the pump 2 is activated to enable oil supply (Step 1). In this state,
Insert the tip of the nozzle into the fuel tank and pull up the nozzle lever to begin refueling.

On the other hand, attach the oil type display member F to display the oil type on the fuel filler cap A.
If not, the control device 7 determines that the data cannot be read (Step C), and outputs a message to the display 8 and to the alarm 20 urging the user to attach the oil type display member. (Step Nu). In addition, if the oil type data can be read but does not match the pre-registered data (Step E), a message to that effect will be displayed on the display 8 or the alarm 2° to prompt the user to confirm the oil type. (Step Nu)
.

In this way, when the amount of oil supplied reaches a predetermined amount and the nozzle lever is pulled down, the oil supply stops. When the nozzle 5 is returned to the nozzle hook and the nozzle switch is turned OFF (Step 3), the control device 7 The fuel pump 1 is stopped, and the presence or absence of a signal from the sensor 11 is checked, and if the fuel filler cap is still left undisturbed on the mounting portion 9, the alarm 20 is activated to call attention to it (Step N).

In this embodiment, a fuel filler cap mounting portion is provided on the fuel supply device main body, but as shown in FIG. It is clear that the same effect can be obtained even if the portion 22 and the sensor 23 are provided.

(Effects of the Invention) As described above, in the present invention, the fuel filler cap mounting section is provided on the fuel supply device main body or a stand disposed near this. A sensor is installed on the loading section to read data on the fuel oil in the vehicle, and the type of oil is determined based on the signal from the sensor. This eliminates the need for a mechanism to pull the beber from the vehicle fuel tank. The type of oil inside can be determined reliably.

Further, since refueling cannot be performed unless the fuel filler cap is set in a predetermined position, it is possible to prevent the fuel filler cap from becoming dirty due to being left on the ground.
