3.目前我国研制生产的移动式功率油耗仅有哪几种?各有哪些特点? 答:功率和油耗率的传统测试方法是发动机的台架实验,由于其测试过程要求高,操作上较复杂,加上拆卸和安装等辅助时间过长,不适合广大农机部门采用,因此,一些农机单位在满足一定测试精度的条件下,考虑到使用的方便性和简易性,研究和生产了一些快速测量拖拉机功率和油耗的仪器,即便携式功
3. At present, China’s development and production of mobile power consumption only a few? What are the characteristics of each? A: The power and fuel consumption of the traditional test method is the engine bench test, due to its high test requirements, the operation is more complex , Coupled with disassembly and installation of auxiliary time is too long, not suitable for the majority of agricultural departments to adopt, therefore, some agricultural machinery units to meet certain test accuracy conditions, taking into account the convenience and ease of use, research and production of some rapid measurement Tractor power and fuel consumption of the instrument, that portable power
