Research and design of electric fuel pump testing system

The electric gasoline pump is one of the most important components of vehicle fuel supply system. It acts a main role to reduce fuel consumption and harmful emissions. It is designed to draw the fuel which has enough pressure and flowrate through the fuel line to the system. According to the drawbacks of current performance testing method used in automobile electric fuel pump experiment;, a new testing system based on single chip microprocessor was developed. The system can automatically accomplish the functions of data sampling, data processing, data storage, statistical analysis and dynamic display for fuel pump parameters and give out overall evaluation. Through actual testing, the results indicate that the system can effectively improve the precision, efficiency and stability of electric fuel pump test.
