Diesel oil heating oil quantity sensor

Abstract

In order to enhance the reliability of an oil tank and achieve functions of tilting motion prevention, oil quantity measurement and diesel oil heating, the invention provides a diesel oil heating oil quantity sensor comprising a supporting seat and a plurality of data tubes of reed capsules. The data tubes are connected with the supporting seat and uniformly distributed along a height direction, and magnetic floats capable of moving up and down are sleeved outside the data tubes; the supporting seat is also connected with an oil tank oil feeding tube and an oil tank oil returning tube which are respectively communicated with a supporting seat oil discharging port and a supporting seat oil returning port through oil paths inside the supporting seat; the head part of the oil tank oil feeding tube is provided with a filtering net and a temperature sensor, and the oil tank oil feeding tube is internally provided with an electric heating body; an intelligent heating circuit control plate is directly arranged in a cavity of the supporting seat, a heating wire, the temperature sensor and the intelligent heating circuit control plate are connected with each other, wire connecting terminals are led out from the intelligent heating circuit plate, and signal terminals are led out form the data tubes; and the supporting seat is also provided with a tilting motion preventing breather valve.

Description

technical field [0001] The invention relates to an oil quantity sensor on an automobile oil tank using a diesel engine. Background technique [0002] At present, the main use of the fuel tank is the pendulum sensor, which has a short life and poor accuracy. In order to solve the problem of poor precision of the pendulum sensor, there has been a sensor that uses the magnetic field to control the contact on and off in the reed tube, and converts the measured change into an output signal to measure the oil level. The oil quantity sensor includes a column with a plurality of reed tubes evenly distributed in the height direction, and a float that can move up and down is covered on the column, and a magnet for inductive reed tube is arranged on the float. The detection accuracy of this electronic sensor is high. The Achilles’ heel of diesel engine is that it can’t start normally in winter and severe cold due to diesel wax formation, and 0# diesel can’t be used at around zero tem...

AI Technical Summary

Problems solved by technology

In order to improve the function, an anti-dumping vent valve, heater, liquid level sensor, oil inlet pipe with coarse filter, and oil outlet pipe are installed on a fuel tank. There are many openings and solder joints on the fuel tank, which not only increases the production cost, but also makes the fuel tank reliable. decreased sex
