XG—15功率油耗检测仪的研制

OUTPUT AND SPECIFIC FUEL CONSUMPTION DETECTOR MODEL XG15

为了同步测量１５ＫＷ以下的农用手扶拖拉机和小型柴油机的功率油耗，ＸＧ１５功率油耗自动检测仪选用Ｓ形拉压力传感器测量加在柴油机飞轮上的正压力所产生的摩擦力，光电式转速传感测量柴油机的转速，微压力传感器测量柴油机的耗油量，采用单片微机（８０９８）对测得的信号进行运算处理。结果表明，测得的数据可靠，误差小，为小型柴油机的适时检修提供了科学的依据。

For synchronotis detection of the output and specific fuel consumption of theagricultural walking tractor and small diesel engine(less than 20 Sorsepower),the s-shaped pullingpressing sensor is chosen for XG 15 automatic oil coiisumption detectingmeter to detect the friction from the middle pressure imposed on the flywheel of the dieselengine,photoelectronic turning speed sensor to detect diesel engine’s turing speed. micropressure sensor to detect the oil consumption of diesel engine、then the chip microprocessor(8098)is used to treat with the tested signat. Results show that the tested data arereliable,in a low error rate,and supply diesel engine’s timely overhaul wltb sceintific provement.
