Dynamic Development Of Automotive Fuel Line Detection System

With the gradual reduction of the petroleum, natural gas and other non-renewableresources but the increasing of car ownership in China, oil prices also soared, with thepeople’s attention on the issue of fuel consumption, low fuel consumption models are moreand more popular, a lot of automotive energy-saving products came into being; combinedwith people’s awareness of the gradual strengthening of the protection of the environment, carbuyers more concerned about vehicle fuel consumption, low fuel consumption vehiclesfancied getting higher and higher, seek to restrict vehicle fuel consumption voices growing.Automobile manufacturers and engine designers need to know the exact instantaneous fuelconsumption for that engine design and development work on the engine improvements alsoneed to know the instantaneous fuel consumption of the engine. Therefore, the developmentof rapid and accurate measurement of car fuel consumption equipment in a variety ofconditions, has become an important and urgent task.Based on the analysis and summary of current domestic vehicle fuel consumptioninstrumentation widespread problem, according to the fuel level meter existing technologiesand trends, the use of advanced sensor technology, chip technology and display technology,developed a smart new car fuel consumption online testing system. The main content of thefuel consumption of the detection system including hardware design and selection, thestructure was constructed instrument: the establishment of a mathematical model of car fuelconsumption detection system; conducted a fuel consumption detection system softwaredesign and debugging, and proposed measures system interference; conduct confirmatorytests, analyzes the feasibility of fuel used in the detection system theory, finally demonstratedthe expanded uncertainty of the fuel meter to calculate the fuel consumption of the vehicleinstrument under different error probability, the results show that the fuel meter to achieve thedesired design goals, measuring results are reliable and stable.The main innovation is the fuel meter and automatic temperature compensation methodsfor data collection using FAI to improve collection rates, improved accuracy and quickresponse of the fuel meter measurements and the ability to the signal interference.The establishment of the test items, can provide energy saving technology developmententerprise products provide test platform, the establishment of common technical database fortechnological innovation and new product development to provide information support andadvice to help formulate government policy to help users in energy-saving cars saving products provide the basis for market development.
