Path to Intelligent Engine Diagnostics

Part I: Crankshaft Dynamics


Continuous monitoring of key engine parameters allows for identification of the current engine condition, degradation trends, and, most importantly, imminent engine failures.



Excerpt from Whitepaper


On the path to intelligent engine diagnostics, the most important
decision lies firstly with which parameters to monitor, and secondly
with how to process these parameters to extract meaningful information.


Aided by advances in data storage and transmission, continuous measurement
of the instantaneous crankshaft torque at high sample rates and high
precision for such large applications, is a recent and non-intrusive measurement
technique, which can be of high value to the engine owner. Most
importantly, the instantaneous crankshaft torque is a single measurement
which encapsulates simultaneously information regarding the combustion
events in all engine cylinders for every instant, using only a single sensor. In
other words, this measurement acts as a signature for each type of engine
and its condition; i.e. its torque profile.

Mr. Konstantinos Tsitsilonis


Mr Tsitsilonis begun his research career by working on offshore platforms’ energy management projects in the CIMC Raffles shipyard, Yantai.
He then continued working in the Strathclyde University Maritime Safety Research Centre, by focusing on internal combustion engines energy analysis, and by developing a novel systematic methodology for ship propulsion engines energy management.
Following a year in the scrubber retrofit industry, Konstantinos returned to research and development through a joint partnership with Datum Electronics and Strathclyde University, with focus on intelligent engine diagnostics techniques.


"A crankshaft dynamics model is a very useful tool to have as it can be further exploited in a number of ways, so as to provide critical information about the engine."
