提出一种检测发动机功率油耗的自动检测仪,它基于功率和油耗的同步测量方法,采用单片机和传感器技术,仪表性能优于以往同类产品,可适用于手扶拖拉机和小型柴油机功率油耗的测量. An automatic detector for measuring the power consumption of engine is proposed. It is based on the synchronous measurement of power and fuel consumption. It adopts single chip microcomputer and sensor technology. Its performance is better than that of its predecessors. It is suitable for the measurement of power consumption of walking tractor and small diesel engine.
