Diesel locomotive fuel-oil-metering detecting device and detecting method

Abstract

The device and method used in internal-combustion engines for detecting and measuring fuel with simple structure and accurate measurement feature that the oil inlet sensor and the returning oil sensor are connected to the single chip, via signal processing circuit through the photoelectric isolation, the display, the man-machine interface, the power module, the jack of manual operator, the 'watch dog' circuit are connected to the single chip respectively. The high accurate math model, the intelligent flow calculation system and anti-interference measures make the system possible to work under harsh environments in strong shock, high temperature and strong interferences, giving accurate measuring of flux of light diesel oil.

Description

technical field [0001] The invention relates to a fuel metering and detecting device and method, in particular to a fuel metering and detecting device and method for diesel locomotives. Background technique [0002] my country's railway locomotive maintenance department is facing the reform of the locomotive maintenance system, changing "regular inspection scope repair" to "regular inspection status repair", that is, on-demand maintenance. And in today's increasingly serious global energy crisis, how to reduce energy consumption and waste is also the focus of the world's general attention. In my country's railway system, the energy consumption cost of the locomotive department that provides traction power has accounted for about one-third of the railway bureau's transportation cost. In particular, the fuel consumption of diesel locomotives is the main part of the transportation cost of the railway system. Due to the influence of rising internationa...

AI Technical Summary

Problems solved by technology

The current locomotive depots lack the necessary scientific means to manage and assess the fuel consumption of locomotive crew members. They can only be assessed by locomotive group, and cannot be assessed by shift.

In addition, when locomotive crews hand over oil during the handover process, they can only rely on eye observation and estimate the approximate oil consumption based on experience, and there is no more accurate objective measurement basis.

At present, the scale line of the fuel tank oil scale of diesel locomotives is in units of 100 liters, and changes of less than 100 liters cannot be observed with the naked eye to achieve the necessary accuracy, so it is impossible to accurately calculate the actual fuel consumption of the crew of each train

Due to the differences in the parking positions of the locomotives, the maximum fuel error observed from the fuel gauge of the locomotive fuel tank can reach more than 300 liters, and the measurement of fuel consumption is extremely inaccurate
