    Abstract: A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be configured to obtain information identifying a previous amount of wear of the piston pin bore and information identifying a wear limit; determine a base piston pin bore wear rate; calculate an effective piston pin bore wear rate based on the base piston pin bore wear rate; determine an amount of time between a current time and a time when the previous amount of wear of the piston pin bore was calculated; and calculate a current amount of wear of the piston pin bore based on the previous amount of wear, the amount of time, and the effective piston pin bore wear rate. The electronic control module may further be configured to calculate an amount of damage to the piston pin bore based on the current amount of wear and the wear limit.

    Abstract: A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be configured to obtain information identifying a previous amount of wear of the piston ring and information identifying an initial dimension of a coating of the piston ring; determine a piston ring wear rate based on a cylinder pressure associated with the piston; determine an amount of time between a current time and a time when the previous wear of the piston ring was calculated; calculate a current amount of wear of the piston ring based on the previous amount of wear of the piston ring, the amount of time, and the piston ring wear rate; calculate an amount of damage to the piston ring based on the current amount of wear and the initial dimension; and take a remedial action when the amount of damage exceeds a threshold.

    Abstract: A machine may comprise a memory configured to store liner polish information; and an electronic control module. The electronic control module may be configured to: determine a load factor based on an amount of load on the engine; determine an end of injection factor associated with the engine; determine a liner polish rate based on the load factor and the end of injection factor; obtain, from the liner polish information stored in the memory, information identifying a previous amount of damage to the engine; determine an amount of time between a current time and a time when the previous amount of damage was calculated; calculate a current amount of damage to the engine based on the previous amount of liner polish, the amount of time, and the liner polish rate; and take a remedial action based on the current amount of damage.

    Abstract: A piston-connecting rod assembly for an internal combustion engine includes a piston pivotally mated to a connecting rod by a piston pin. The piston pin includes a first pin end, a second pin end, and a midsection. When assembled, the first pin end and second pin end are respectively received in a first pin bore and second pin on the piston while the midsection is accommodated in a cross-bore through the connecting rod. The piston pin may include a wear resistant layer applied over at least a portion of its external surface that may include at least one of tungsten disulfide and molybdenum disulfide. The wear resistant layer may be applied as part of a manufacturing process performed on the piston pin.
