What is CoRoM? Objective: Main purpose of CoRoM is to succeed receiving and monitoring temperature directly from engine connecting rod upper bearing shell and optionally measure the piston lubrication oil temperature, so that to provide vital data of ; ü connecting rod upper bearing shell condition (the most critical point) ü any bearing seizure at very early stage ü continuos control & monitoring of con-rod bearing and oil temperature by Wireless & Batteryless Sensing Node with Energy Harvesting System, and transferring all data via Wi-Fi / BLE to the Main Control Panel to establish...

What is CoRoM? CoRoM consist of two sensors; Bearing Cap Sensor and Lub-oil sensor (optional); • Bearing Cap sensor measures the temperature of ConRod upper bearing cap closest point to upper bearing shell, where the highest bearing load exist and most of the failures begin • Lub-oil sensor measures the temperature of lube oil going to piston crow

CoRoM Bearing Cap sensor The temperature of ConRod upper bearing shell is measured by a PT100 sensor, located in the groove of ConRod upper cap with or without drilling a hole to get upper bearing shell temperature Surface touch, no drilling Drilling sensor hole to upper bearing shell

CoRoM Lub-oil sensor CoRoM Lub-oil sensor, measures the lube oil temperature going upwards to piston crown by a PT100 sensor. The sensor hole is drilled vertically on the upper cap of ConRod to reach the oil passage. Lub-oil sensor hole drilling

Evaluation of CoRoM data Slight or sudden increase in CoRoM Bearing Cap sensor, is an indication about siezing of ConRod upper bearing shell temperature. Increase in CoRoM Lub-oil temperature will provide an additional data about the ConRod bearing condition.

Advantages of CoRoM ü CoRoM is a system that has not been developed until now in diesel engine technology, and is able to obtain data directly from the ConRod bearing. ü CoRoM will give us faster and more accurate data, early warning before the failure happen comparing to existing temperature Splash Oil Monitoring or Oil Mist Monitoring systems ü Wireless, battery-free, able to generate its own energy. ü CoRoM will provide proactive approach maintenance ability by continious monitoring

SPLASH OIL and OIL MIST MONITORING SYSTEMS ; ü Existing Splash Oil Monitoring System is to receive data from the splashing oil unclear from where it has splashed at that moment will give us a common alarm and needs to be checked whether a failure in the liner, piston rings, or skirt, or connecting rod bearing or any. üSPMS or OMD is able to give alarm after the failure happened ü But CoRoM will give us data directly from the source and will establish a much better, safer and faster analysis opportunity before the failure reached to the crankshaft.

Thanks to CoRoM, by this very specific continuous measurement we will have a chance to minimize the cost, time and generation loss of mulfuntion of connecting rod bearing, with a preventive, predictive and superior technological approach.
