| Abstract: | This article introduced the characteristics of C8051F040 and presented the apphcation of C8051F040 in the engine fuel comsumption, especially introduced the main features of the engine fuel comsumption . A system of data collection was make up of C8051F040, a bridge transducer ADC named AD7730 and pressure sensor , which can collect high precision data. Then the collected data can be analyzed and accounted in C8051F040. Account for every need , C8051F040 output the control signal of PWM for switch which is controlled by the switch of valve circuit. The engine fuel comsumption can be used for fuel comsumption measure. |
