Abstract

The invention discloses an intelligent vehicle oil amount measurement detection system which aims at providing the intelligent vehicle oil amount measurement detection system which is suitable for vehicle-mounted measurement of a diesel motor and has simple structure and accurate and reliable measurement. An output shaft of a driving motor of a measurement pump is connected with the measurement pump; an oil inlet of the measurement pump is connected with a control valve; an oil outlet of the measurement pump is connected with the oil inlet of a diesel drop tank; the oil outlet of the diesel drop tank is connected with the oil inlet of a low-pressure pump of the diesel motor; an output end of the driving motor of the measurement pump is provided with a revolution sensor; a liquid level sensor is arranged in the diesel drop tank; and the liquid level sensor and the revolution sensor are respectively connected with a central processing unit. The measurement detection system solves the problem of vehicle oil consumption measurement taking diesel oil as energy, provides a guarantee for the convenience of measurement, management of power generating machines and energy conservation, and has simple structure, accurate and reliable measurement, low cost and convenient installation.

Description

technical field [0001] The invention relates to a vehicle-mounted fuel quantity measurement and detection system, more specifically, relates to a vehicle-mounted fuel quantity measurement and detection system for an engine that uses diesel as fuel. Background technique [0002] The premise of saving energy is to know how much energy is used. On this basis, the existing energy can be scientifically managed and fully used, so as to improve the efficiency of energy use, improve the service life of the engine, increase the ratio of input and output, and achieve saving energy purpose. [0003] At present, there are two methods for measuring the fuel consumption of machines that use fuel oil as energy, both internationally and domestically, one is the volumetric method (mainly used for fuel metering of gasoline engines); the other is the gravimetric method (mainly used for diesel engines fuel metering). The two methods can only be used for routine tests of laboratory bench engin...
