Abstract

See full text

A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be 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; and take a remedial action based on the current carbon deposit growth. The current carbon deposit growth may be calculated based on: a previous carbon deposit growth on the piston, 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.
