System for determining piston damage based on carbon deposit growth

A method for monitoring carbon deposit growth on a piston of an engine, the method comprising:

• obtaining, by an electronic control module and from carbon deposit growth information stored in a memory, information identifying a previous carbon deposit growth on the piston;
• obtaining, by the electronic control module and from the carbon deposit growth information stored in the memory, information identifying a time when the previous carbon deposit growth was calculated;
• determining, by the electronic control module, a temperature of a bowl rim of the piston;
• calculating, by the electronic control module, a temperature of an oil gallery of the piston based on the temperature of the bowl rim;
• determining, by the electronic control module, a carbon deposit growth rate of the piston based on the temperature of the oil gallery;
• determining, by the electronic control module, an amount of time between a current time and the time when the previous carbon deposit growth was calculated;
• calculating, by the electronic control module, a current carbon deposit growth the piston based on the previous carbon deposit growth, the amount of time, and the carbon deposit growth rate;
• and
• taking, by the electronic control module, a remedial action based on the current carbon deposit growth.

A machine comprising:

• a piston;
• a memory configured to store carbon deposit growth information,
• the carbon deposit growth information including information identifying a previous carbon deposit growth on the piston;
• and
• an electronic control module configured to:
• determine a temperature of a bowl rim of the piston;
• calculate a temperature of an oil gallery of the piston based on the temperature of the bowl rim;
• determine a carbon deposit growth rate of the piston based on the temperature of the oil gallery;
• determine an amount of time between a current time and the time when the previous carbon deposit growth was calculated;
• calculate a current carbon deposit growth on the piston based on:
• the previous carbon deposit growth,
• an amount of time between a current time and a time when the previous carbon deposit growth was calculated, and
• the carbon deposit growth rate;
• and
• take a remedial action based on the current carbon deposit growth.
