Embodiment Construction

[0014] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0015] A fuel gauge indication method for the amount of overflowing oil in an automobile fuel tank, wherein the actual maximum capacity of the automobile fuel tank is 50 liters; figure 1 As shown, the scale on the indicating plate 100 of the fuel gauge has four grids in total, namely the first grid 101 , the second grid 102 , the third grid 103 , and the fourth grid 104 . When the pointer 200 of the fuel gauge indicates full scale, the pointer 200 indicates the rightmost position on the first grid 101 . As the fuel is consumed, the pointer moves counterclockwise through the first, second, third and fourth grids.

[0016] When the pointer 200 of the fuel gauge just indicates that it is full, the resistance of the fuel sensor is 100 ohms, and the volume corresponding to this resistance is 45 liters; The resi...

Abstract

The invention discloses a fuel gauge indication method for an overflowed fuel amount of an automobile fuel tank. The fuel gauge indication method comprises the following steps: an actual initial fuel amount in the automobile fuel tank is assumed to be (X-2) liters; before the fuel tank is released from a fuel filling overflowing state, a pointer of a fuel gauge moves for 1 / [(X-2)-B2] squares when one liter of fuel is consumed; when an actual fuel amount of the fuel tank is reduced to B1 liters, a consumed fuel amount, namely X1 liters, is obtained, wherein an accurate initial fuel amount is (B1+X1) liters; a residual step number of the pointer of the fuel gauge in a first square moves for {1 / X1 / [(X-2)-B2]} / (B1-B2) squares when one liter of the fuel is consumed; and the pointer of the fuel gauge moves for 1 / [BN-B(N+1)] cells in the Nth square when one liter of the fuel is consumed. The method disclosed by the invention can really reflect a fuel content consumption amount when the automobile fuel tank is in the overflowed state, so that a user can accurately estimate the fuel amount in the fuel tank through the fuel gauge.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a fuel gauge indicating method for overflowing fuel from a fuel tank of an automobile. Background technique [0002] From the perspective of vehicle safety and the characteristics of thermal expansion and contraction of fuel, automobile manufacturers will leave a certain space when designing the fuel tank. The "fuel tank capacity" marked in the car instruction manual is not the actual capacity of the fuel tank, but the safe capacity. If the car owner chooses to fill up directly during the refueling process, he will find that the actual refueling volume may be higher than the "fuel tank volume". The automobile fuel gauge calculates and indicates the fuel quantity based on the resistance value of the fuel sensor in the fuel pump. However, due to the limitations of the fuel tank structure and fuel pump structure, the fuel sensor cannot detect the fuel q...
