针对电控柴油机的挖掘机燃油消耗量测量不便的问题,本文提出了一种新的测量方法。此方法在不改装挖掘机燃油管路的情况下,充分利用了电喷发动机控制信息,将各缸的供油信息进行标定、采集,将数据通过计算机运算后输出测试过程中的燃油消耗量,通过对测量原理和测量误差的分析,确定了系统测量方案,并从硬件与软件两个方面对设计方案进行阐述。从现场试验数据得出,该系统实现了电控柴油机挖掘机的燃油消耗量的实际测量,有较好的实用性,操作简单,测量方便。
Aiming at the problem of inconvenient measurement of fuel consumption of excavators for electronically controlled diesel engines, this paper proposes a new measurement method. This method makes full use of the control information of the EFI engine without modifying the fuel line of the excavator, calibrates and collects the fuel supply information of each cylinder, and outputs the fuel consumption of the test process through the computer operation. Through the analysis of measurement principle and measurement error, the system measurement scheme was determined, and the design scheme was elaborated from two aspects of hardware and software. According to the field test data, the system realizes the actual measurement of the fuel consumption of the electronically controlled diesel excavator, which has good practicality, simple operation, and convenient measurement.
