Connecting Rod Monitoring

Don't React After Failure — Prevent It Before: Meet CoRoM

In traditional diesel engines, connecting rod bearing failures are typically detected through Splash Oil Monitoring Systems (SPMS) or Oil Mist Detectors (OMD). But these systems:

Only generate alarms after a failure has occurred
Cannot pinpoint the exact source of the issue
Trigger a common alarm whether the problem is in the liner, piston, rings, or bearing

Since they don't directly measure temperature, they offer no real-time precision for early action.

Real-Time Data from Critical Components with CoRoM

CoRoM (Connecting Rod Monitoring) is the first system in diesel engine technology that directly measures the temperature of the upper connecting rod bearing.

Works wirelessly and battery-free
Generates its own energy via energy harvesting
Sends data through BLE or Wi-Fi

It includes two sensor types:

Bearing Cap Sensor – placed in the upper cap, measures bearing shell temperature directly
Lub-Oil Sensor – monitors the temperature of lubrication oil flowing upward to the piston

This allows you to detect bearing wear, early seizure, or lubrication failures before damage spreads.

From Guesswork to Real Insights: Predictive Maintenance with CoRoM

With CoRoM, you can:

Catch issues early before they escalate
Optimize maintenance schedules
Plan spare part supply, manpower, and downtime efficiently
Protect expensive parts like the crankshaft from failure

While traditional systems report what has happened, CoRoM tells you what will.

Description:
Main purpose of CoRoM is to succeed receiving and monitoring temperature directly from Diesel Engine connecting rod upper bearing shell and optionally measure the piston lubrication oil temperature, so that to provide vital data of:
- connecting rod upper bearing shell condition (the most critical point)
- any bearing seizure at very early stage
- continuos control & monitoring of con-rod bearing and oil temperature
by Wireless & Batteryless Sensing Node with Energy Harvesting System, and transferring all data via Bt or LoRa to the Main Control Panel to establish preventive, informative and protective early warning system and try to minimize the Connecting Rod Bearing and Piston Failures encountered in diesel engines.

Revolutionizing Connecting Rod Bearing Monitoring

CoRoM is a wireless and batteryless sensing node with energy harvesting system that provides direct measurement of the temperature from the ConRod bearing, the most critical point in diesel engines. By continuously monitoring via Bt or LoRa the ConRod bearing and oil temperature, CoRoM offers a proactive approach to maintenance, providing an early warning system for bearing seizure, and avoiding catastrophic engine failure. CoRoM's innovative technology offers a revolutionary approach to connecting rod bearing monitoring in diesel engines, which can lead to significant cost savings and improved engine performance.

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

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.

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.

Splash Oil and Oil Mist Monitoring

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. SPMS or OMD is able to give alarm after the failure happened 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.

What is CoRoM?

CoRoM is an innovative system designed to monitor the condition of the connecting rod upper bearing shell in diesel engines. It consists of two sensors: the Bearing Cap Sensor and the Lub-oil Sensor. The Bearing Cap Sensor measures the temperature of the con-rod upper bearing cap closest point to the upper bearing shell, while the Lub-oil Sensor measures the temperature of the lube oil going to the piston crown. The system is wireless, batteryless, and able to generate its own energy, making it easy to install and operate without requiring frequent maintenance.

How does CoRoM work?

CoRoM uses a Bearing Cap Sensor and a Lub-oil Sensor to monitor the temperature of the engine connecting rod upper bearing shell and lubrication oil temperature, respectively. The sensors wirelessly transfer the data to a main control panel, which establishes an early warning system to help prevent engine failures.

How is CoRoM different from other monitoring systems?

CoRoM is the first wireless, batteryless, and self-powered system to monitor the engine connecting rod upper bearing shell directly, providing early and accurate data to prevent engine failures. Other systems, such as Splash Oil Monitoring or Oil Mist Monitoring, are not as precise and can only provide an alarm after a failure has already occurred.

Can CoRoM be used with any type of diesel engine?

Yes, CoRoM can be used with any type of diesel engine, including marine, power generation, and industrial applications.

How often should CoRoM be checked or calibrated?

CoRoM is designed to require minimal maintenance and calibration. However, it is recommended to check the system periodically, as recommended by the manufacturer or a qualified technician.

What are the technical specifications of CoRoM?

CoRoM uses a temperature sensor and has a sampling refresh rate of 500ms -1 second. The system consumes less than 500 μW of power and has a data transmission range of +8 dBm. The operating temperature range is between -40 to +105 Celsius.

What is the power source for CoRoM?

CoRoM is powered by advanced energy harvesting technology. It generates its own power from the movement of Connecting Rod, eliminating the need for batteries or external power supplies. This self-sustaining power system ensures that CoRoM operates continuously and reliably without the need for frequent maintenance or battery replacements.

For whom was CoRoM developed?

CoRoM was developed for industries that rely heavily on diesel engines, such as marine, power generation, and industrial applications. It is particularly useful for maintenance teams, engineers, and operators who are responsible for ensuring the reliability and performance of diesel engines. CoRoM provides them with real-time data and early warnings about potential engine failures, helping to avoid costly repairs and minimize downtime.

What are the benefits of using CoRoM?

CoRoM provides early and accurate data on engine conditions, allowing for proactive and preventative maintenance to prevent engine failures. This can save time, money, and reduce the risk of downtime or catastrophic engine failures.
