挖掘机电喷柴油机普遍采用CAN总线技术,对柴油机转速进行控制,即油门硬特性控制。电喷柴油机的油门控制方式有线性油门、开关油门、频率油门、远程油门以及J1939多路传输油门等。本文介绍J1939多路传输油门。1.结构组成J1939多路传输油门控制系统主要由主泵1、柴油机2、柴油机控制器3、电子监控器4、油门旋钮5、主控制器6、前泵压力传感器7、后泵压力传感器8、先导压力传感器9和主泵电比例减压阀10等组
Electric excavator diesel excavator commonly used CAN bus technology, the control of the diesel engine speed, throttle hard control characteristics. EFI Diesel throttle control linear throttle, switch throttle, frequency throttle, remote throttle and J1939 multiplex transmission throttle. This article describes the J1939 multiplex transmission throttle. 1. Structure J1939 multi-channel throttle control system consists of the main pump 1, diesel engine 2, diesel engine controller 3, electronic monitor 4, the throttle knob 5, the main controller 6, the front pump pressure sensor 7, the rear pump pressure sensor 8 , The pilot pressure sensor 9 and the main pump proportional valve 10 and other groups
