2-1/16 inch fuel level gauge
The automobile instrument panel includes speedometer, tachometer, water temperature gauge and oil gauge. The style of the instrument panel can be improved for some models, but the display principle is basically the same. The car oil gauge is usually distinguished by the icon of a gas station and a gas dispenser, where f is full and E is that the remaining oil in the tank is not much.As picture shows below;
Therefore, the automobile oil gauge is still easy to understand. Of course, the design of some automobile oil meters will also be different. For example, as shown in the figure, there are no English letters F and E, but in the form of scores. In addition, the F and e of the automobile oil gauge are also well understood. F on the oil gauge means full, and the initials of full are used; Some people think that e means empty and uses the initials of empty, but thinks that e should mean enough. Even when the oil gauge points to e, there will be a small amount of oil in the tank to support you to drive to the gas station. The oil quantity displayed by the oil gauge is connected with a metal rod through a floating ball in the oil tank. This principle is similar to the toilet water tank in the toilet. The tail end of the metal rod connected with the floating ball will be connected to a variable resistance through a movable contact. The change of the position of the floating ball on the oil level in the oil tank will also change the position on the variable resistance through the metal rod, The variable resistance will be connected to the fuel gauge of the car, and the action of the pointer of the fuel gauge will be controlled by the amount of electric flow through the variable resistance.
Sometimes you will find that the fuel warning light will flicker on and off when passing through bumpy roads or going uphill and downhill. In fact, this is because the height and position of the floating ball are changed due to various actions of the car. Therefore, when the owner looks at the oil gauge, it is mainly based on the vehicle running in a straight line on the plane.
