QCJK-I/S8 Diesel Engine Controller

QCJK-I/S8 Diesel Engine Controller

A. Product Overview

QCJK-I/S8 diesel engine monitor is a fully automatic diesel engine and generator electronic measurement and control system controlled by a microcomputer. It can accurately detect and display diesel engine speed, oil pressure, water temperature, oil temperature, gearbox pressure, and can timely monitor the above measured parameters according to user settings, send out sound alarm, light alarm, remote alarm and other signals, set the start and stop functions, and send out a stop signal to control the electric actuator to cut off the fuel oil circuit when the parameter exceeds the stop value, automatically control the diesel engine to stop in an emergency, and protect the diesel engine to the maximum extent. At the same time, the corresponding remote display can be optionally equipped to realize remote monitoring of diesel engine operating parameters. This monitor has the advantages of advanced design, small size, high measurement accuracy, reliable operation, digital display, easy operation and installation, etc. It can be used for various types of diesel engines such as ships and land-based power stations. It is a new generation of electronic instrument system that realizes the mechatronics of diesel engine products and a replacement product for diesel engine pointer instruments.

The design of this product meets the requirements of the CCS specification of China Classification Society.
