Abstract
A method for estimating wear of at least one component of an internal combustion engine includes receiving sensor information and fuel commands indicative of an amount of fuel supplied to at least one combustion chamber of the internal combustion engine and determining an incremental increase in an amount of wear of at least one component of the internal combustion engine based on at least the sensor information and the fuel commands. The method also includes determining an updated amount of wear based on the incremental increase in the amount of wear, and outputting a notification indicative of the updated amount of wear.
Claims20
A method for estimating wear of at least one component of a valve train of an internal combustion engine, comprising:
- receiving sensor information and fuel commands indicative of an amount of fuel supplied to at least one combustion chamber of the internal combustion engine;
- determining an incremental increase in an amount of wear of the at least one component of the valve train of the internal combustion engine based on at least the sensor information and the fuel commands;
- determining an updated amount of wear based on the incremental increase in the amount of wear;
- and
- outputting a notification indicative of the updated amount of wear.
A method for estimating wear in a valve train of an internal combustion engine, comprising:
- receiving sensor information indicative of an operation of the internal combustion engine over a first period of time;
- determining, based on at least the sensor information for the first period of time, a first incremental increase in an amount of wear of at least one component of the valve train;
- receiving sensor information indicative of the operation of the internal combustion engine over a second period of time;
- determining, based on at least the sensor information for the second period of time, a second incremental increase in the amount of wear;
- determining, based on the first incremental increase and the second incremental increase, an updated amount of wear;
- and
- outputting a notification indicative of the updated amount of wear.
A wear estimation system for an internal combustion engine, the system comprising:
- a fuel injector configured to inject fuel toward a combustion chamber;
- a sensor configured to output information indicative of an amount of fuel supplied to the internal combustion engine;
- at least one valve train component;
- and
- a controller configured to:
- control an operation of the fuel injector by outputting commands to the fuel injector;
- receive the information output from the sensor;
- determine an incremental increase in an amount of wear of the at least one valve train component based on at least the sensor information;
- update the amount of wear based on the incremental increase;
- and
- output a notification indicative of the updated amount of wear.
