Description

The utility model relates to measuring systems and devices of land vehicles, which will be installed on them as additional options, as an addition to existing systems, or as standard equipment of vehicles, which will be installed in factories producing vehicles. The fuel level indicators currently in operation on all vehicles do not give an idea of the exact amount of fuel remaining in the fuel tank, but only signal to the driver which part of the fuel is still left (1/2, 1/3, 1/4, ...) and the upcoming the end of it and the need to refuel the fuel tank for the next trip.

The proposed device "Fuel measuring system of a vehicle" provides a strict accounting of fuel consumption with an accuracy of 10 milliliters on all types of vehicles for the entire period of many years of operation. There are a large number of inventions and utility models on this subject.

A magnetoelectric device for controlling the fuel level in a tank is known (See Galkin Yu.M. “Electrical Equipment of Tractors and Cars”, Mashgiz Publishing House, 1960, pp. 249-250), consisting of a rheostat-float sensor located in the fuel tank and connected to on-board electrical network of the instrument panel, through the ignition switch.

Such a fuel level indicator does not give a complete picture of the exact amount of fuel in the tank, but shows only approximate data.

There is also the invention of “Fuel meter in the tank of a vehicle” RU 2344381 C1, A. Lozhkin Lysanov N.G., May 25, 2007, published January 20, 2009, which presents a device for measuring spent fuel for a specific trip. The device is attached to the standard neck of the fuel tank and, by pushing into the tank, a probe with a sensor for touching the fuel surface is introduced, and inside the hollow probe, a pressure sensor is located, and the probe moves along a guide that functions as a reference point for the probe to move. This method of measuring the fuel level manually was developed for the operation services of motor transport enterprises to control fuel consumption at the end of work.

Known RF patent No. 2262084 "Resonance acoustic level gauge", published 10.10.2005, the Fuel Level is determined by measuring segments of the tube mounted vertically in the tank, in which the corresponding sensors are mounted.

The invention is known "Device for measuring the liquid level in a vehicle’s capacity". USSR copyright certificate No. 657262. Published 04/15/1975. The measurement is based on a liquid column pressure sensor. The liquid column pressure is proportional to the fuel level in the tank.

Closest to the proposed device is the Utility model RU 136565 U1, Anpilov S.M. and Sheludko S.I. "A device for metering fuel consumption by a vehicle." Published January 10, 2014

The device is mounted on a regular fuel tank of a car. On the fuel filler pipe between the neck and tank, a counter and a data logger are installed, which are connected by communication channels to an external interface, which, in turn, is connected to an electronic display of fuel readings in the passenger compartment. In addition, the external interface unit is connected to a mobile receiver (smartphone) and to a stationary receiver (computer).

The device operates as follows: A fuel gun is inserted into the neck of the fuel tank and the fuel supply is turned on. The meter on the fuel line measures the amount of fuel injected, and the registrar saves information for each refueling cumulatively. Data is sent to an interface that calculates the nominal amount of fuel and issues this data to an electronic display in the vehicle interior. At the same time, information is fed to mobile and stationary receivers.

The disadvantages of this device are the following:

1. Since the device’s counter on the fuel line between the neck and tank works only under natural fuel drainage (there is no excess pressure at the gas station pump, because the neck of the tank is open during refueling), it will, firstly, prevent the passage of fuel into the fuel tank with its impeller, and secondly, it will work with an unacceptable error due to a jet break. Also, the registrar will interfere with the promotion of fuel. Installation of these two devices in the fuel line can provoke a fuel overflow through the neck of the tank to the ground due to obstacles in the passage of fuel into the fuel tank.

2. The meter in the fuel line of the fuel tank, even if it has been verified and tuned exclusively precisely, only duplicates the meter reading at the gas station. The inconsistency of the readings of the two meters, in fact, on the same pipe, cannot be evidence of underfilling, since the meters work in different conditions, one under the pressure of the fuel pump at the gas station, and the second on the bursting jet. Clearly, the first meter, at the gas station, is more accurate. That is, a more accurate accounting of fuel does not work!

3. Tracking the route of the car at any time is not new, since it has long been used by installing satellite navigation beacons or navigators on cars.

The essence and novelty of the proposed utility model is as follows.

In the proposed device, the fuel measuring system of the vehicle, the main role in accurately calculating the volume of fuel is played by a calibrated fuel tank. Regardless of the meter reading at the gas station, the calibrated fuel tank plays the role of a counter measurer - an independent calculator of the volume of fuel poured into it. Here, any errors and errors in the calculation of the fuel volume are excluded, and the accuracy of the calculations is graduated (calibrated) in increments of 10 ml. After calibrating the fuel tank, all equipment is sealed by the manufacturer in order to prevent outsiders from accessing software and fuel tank sensors. Calibration accuracy is confirmed by a single international protocol, in the language of the consumer’s country. In the event of a dispute, the accuracy of measurements is determined at any gas station, by loading fuel from a standard measuring device, which is mandatory at the gas station.

Also new is the device of four symmetrically located sensors with rod magnetic receivers and sliding floats, with magnetic chips sealed in them. Electronic devices with liquid crystal or touch displays are not new and have long been used in automobiles, but the software created specifically for the proposed device is new.

The technical result of the utility model is achieved as follows (see Fig. 1, Fig. 2 and Fig. 3): Inside the gas tank - 1, four additional vertical hollow non-metallic rods (tubes) - 2 are installed, each of which is free up and down in outer diameter the float moves - 3 from a gas-resistant material with a magnetic sensor 6 - by a CHIP sealed inside the float. Inside the hollow rods there are rod magnetic receivers sensitive to movement of the floats 7 — magnetic coils along the entire height (or others), which at any time determine the position of the floats in any place by the height of the hollow rod. The average value for the height of all four floats in the fuel tank is translated - transformed by the converter - 4 signals of magnetic receivers into liters of fuel residues at any time and transmitted as a digital signal to the electronic board of the on-board computer - 5 with the appropriate software. The device should support the ability, by pressing a button or by touch, to fix the amount of fuel in the fuel tank before refueling and after refueling with the final readings of the volume of purchased and refilled fuel at each individual gas station. There should also be a function of summing the total fuel volume for the entire period of operation, with accurate indications of average fuel consumption.

After equipping the fuel tank with the proposed equipment, each fuel tank must pass the calibration procedure at the stand of the factory that produces fuel tanks. Calibration accuracy is set to 0.01 - one hundredth of a liter, that is, 10 ml, for various inclinations of the gas tank in different directions at an angle of up to 10 degrees inclusive. At the same time, indications of the exact fuel volume for each calibration step are set on the electronic display.

The presence of such equipment will allow motorists, firstly, to control the fuel consumption of their car and timely troubleshoot by adjusting the fuel system, and, secondly, to have accurate information about the amount of fuel remaining in the gas tank and the history of the operation of the car in terms of fuel consumption and cash for the purchase of fuel.

The technical result of the application of the utility model is the exceptional accuracy of measuring the volume of fuel in the vehicle’s fuel tank at any given time, simplicity and reliability in operation for many years of operation. The on-board computer software will include the following data: the date of each gas station, the name of the gas station and its navigation, the gas station number, the price of a unit volume of fuel, the fixation of the amount of fuel accurate to hundredths of a liter before each refueling, the fixation of the amount of fuel accurate to hundredths liters after each refueling, the amount of each refueling to the nearest hundredths of a liter, the cost of each refueling, the total cumulative amount of fuel from the beginning of the operation of the fuel tank with the proposed device and the total amount of media well spent on the purchase of fuel from the beginning of operation, as well as the speedometer of the car and the average fuel consumption per 100 km.

With the advent of compact analyzer sensors, the octane rating of fuel will also be included in this software.

The utility model has the prospect of industrial applications on a large scale.
