Auto Oil Consuption Examination System Research And Development

Automobile development of human civilization and progress of life signs. As a transport vehicle with one hand to transport people's life and production brought great convenience, the other, it also brings environmental pollution and energy shortages. Therefore, the study of motor vehicles to reduce fuel consumption and emissions pollution is the area of one of the key elements.However, the current automobile fuel consumption, especially road test testing apparatus single, testing methods can not be fully reflected in the various vehicle operating conditions and the actual vehicle fuel consumption volume.In light of this situation, the authors analyze and study various automobile fuel consumption test instruments and fuel consumption test methods on the basis of proposed a new fuel consumption tests and test methods.First papers on car fuel consumption test equipment and automotive fuel consumption characteristics of the test methods for the analysis and comparison automobile electronic control of fuel injection system and the principle of the process, automotive chassis dynamometer the principle of analysis. Automobile chassis to road test simulation-based method, By extracting design automobile electronic control fuel injection pulse width injector device to test vehicle fuel consumption of vehicle fuel consumption test system.Briefed the computer of Jinbei Maruili single point of the composition and work principles, this as an example of design and fuel consumption test system hardware connectivity, and its system external circuit.Delphi using object-oriented programming language to prepare a serial debugging software, This software will be installed to personal computers, Then MAX232 chip personal cars and personal computers linking microcomputer, By calling microcomputer vehicle after vehicle sensor signals, Information on these secondary signal processing, through images, figures and forms, such as curves showed that the automobile fuel consumption parameters. Shown here is the instantaneous fuel consumption pulse width, the average fuel consumption of 100 km, within a certain period of time and average fuel consumption within a certain distance of the average fuel consumption. Analysis of the test results, then calculate a vehicle for the best speed and the best working conditions, and the adoption of further comparison and analysis to find out the cause of the high fuel consumption of cars with R & D and production unit. in order for them to improve and new product development.Discussed the types of system errors and errors caused by errors by analyzing the various reasons, summed up the fuel consumption test system may exist in error, and on this basis the system error correction methods and avoid error method.
