小型汽油机在林业生产中应用很广。如油锯、割灌机、喷雾机、挖坑机、风力灭火机等便携式机具,都采用它作为配套动力装置。我所是国家便携式林业机械质量监督检验测试中心,每年都要对这类机具进行试验和测试。传统的方法是用秒表计时,通过度盘读取数据,然后通过人工计算出功率、油耗等参数并绘制特性曲线。这种工作方式容易产生读数不准或不同步现象,影响试验数据测定的精度,且需要较多测试人员。提高小型汽油机试验手段 Small gasoline engine is widely used in forestry production. Such as chain saws, brush cutters, spray machines, digging machine, wind machine and other portable fire extinguishers, have adopted it as a supporting power plant. I am a national portable forestry machinery Quality Supervision and Testing Center, every year to test and test this type of equipment. The traditional method is to use a stopwatch clock, read data through the dial, and then manually calculate the power, fuel consumption and other parameters and draw the characteristic curve. This method of work is prone to readings are not allowed or not synchronized, affecting the accuracy of test data determination, and require more testers.
