QCJK-I/JY Diesel Engine Controller

QCJK-I/JY Diesel Engine Controller

A. Overview

The QCJK-I/JY series diesel engine monitor (hereinafter referred to as the monitor) is a diesel engine electronic measurement and control system controlled by a microcomputer. It is an electronic device that can automatically detect the working condition of the diesel engine and the diesel engine over-limit protection. The monitor can automatically measure, digitally display, and comprehensively monitor and protect the diesel engine's speed, lubricating oil pressure, cooling water temperature, fuel oil level and other parameters, and send out sound and light alarm signals to control the actuator to cut off the fuel oil circuit and automatically control the emergency stop of the diesel engine.

This monitor has the advantages of advanced design, small size, high measurement accuracy, reliable operation, digital display, easy operation and installation, etc. It is a new generation of electronic instrument system that realizes the mechatronics of diesel engine products.
