摘　　要：概述了C8051F040单片机在发动机燃油消耗仪中的应用,并介绍了以其为核心设计的油耗仪的主要特点。C8051F040单片机通过与高精度A/D转换器AD7730、压力传感器组成信号采集系统,采集到高精度的质量信号,并在单片机中对采集到的信号进行分析、处理,根据需要通过输出PWM信号控制来驱动油箱阀门的电磁阀的开闭。所设计的燃油消耗仪可以达到测量发动机油耗的目的。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.
