A coolant circuit for cooling of an engine in a power system. The coolant circuit includes an inlet line and an outlet line. The coolant circuit further includes a heat exchanger with a plurality of heat exchanging elements. The coolant circuit also includes a bypass line disposed in parallel to the heat exchanger, between the inlet line and the outlet line. A control valve is disposed in the coolant circuit regulating the flow of a coolant, such that the coolant flows through the heat exchanger and the bypass line when the control valve is in a fully open position.

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.

A piston for an internal combustion engine includes a piston body forming a crown portion and a skirt portion. The skirt portion includes a bore that is arranged to receive a pin for connecting the piston to a connecting rod. The crown portion forms a bowl surrounded by a flat crown surface having an annular shape. The bowl and flat crown surface meet along a circular edge surrounding a rim of the bowl. The piston further includes an annular protrusion disposed within the bowl adjacent the rim. The annular protrusion has a generally convex shape in cross section that is created by an upper, inwardly extending surface and a lower, inwardly extending surface, which meet along a convex apex.

An internal combustion engine includes a cylinder case forming a cylinder bore having a centerline and an inner bore surface. A piston disposed within the cylinder bore forms a crown surface. A region defined between the piston and the cylinder bore in a radial direction has an annularly shaped mouth opening surrounding the crown surface. A cylinder head is disposed to cover an open end of the cylinder bore such that a variable volume is defined within the cylinder bore between the cylinder head and the piston. The cylinder head also forms a flame deck in fluid contact with the variable volume. A deflector structure forms a portion of the inner bore surface adjacent the flame deck surface, and is disposed between the flame deck and a topmost ring seal groove of the piston when the piston is at a TDC position.
