Abstract: An internal combustion engine includes an engine block including a plurality of cylinders. A cylinder head is mounted to the engine block and includes intake and exhaust passages in communication with the plurality of cylinders. A cylinder head cover is mounted to the cylinder head and defines a cavity between the cylinder head and the cylinder head cover. An oil passage is disposed in the cavity and includes at least one oil jet for spraying oil at a surface of the cylinder head that is heated by the exhaust passages.

Abstract: An oil drain plug is disclosed for cooperating with a socket in an oil sump. The plug includes a main body, an eccentric pin protruding from the main body, and an enlarged tip on an end of the eccentric pin. The socket includes a cup-shaped cavity having a lateral wall open at one end, closed at the opposite end by a bottom wall and including an internal surface for mating with the main body of the plug. The bottom wall includes an external surface facing outside the cavity, a through hole such that the enlarged tip of the plug extends beyond the external surface, and a slot departing from the through hole towards a distal end along an arched path centered in the axis and having a smaller width than the through hole for preventing the enlarged tip of the plug from passing through it.

Abstract: A piston cooling jet for an internal combustion engine includes a body having a coolant duct extending between a coolant duct inlet and a coolant duct outlet fluidly connected to a coolant nozzle. The piston cooling jet includes a plunger having a plunger stem and a plunger head. The plunger is movable within the coolant duct of the body between a closing position that closes the coolant duct inlet and an opening position that opens the coolant duct inlet. The piston cooling jet further includes a biasing spring coupled to the plunger to bias it towards the closing position. A plunger coolant channel has an inlet at the plunger head and an outlet at the plunger stem, channeling coolant downstream of the plunger head when the plunger is in the opening position.

Abstract: A valve for controlling piston cooling jets in an internal combustion engine is disclosed. The valve includes a valve body equipped with an oil inlet for drawing oil from an oil gallery and an oil outlet for connection with a piston cooling jet gallery. The valve body is equipped with an air inlet for drawing air from an intake manifold of the engine, and with a valve element configured to be actuated by the pressure of the oil entering the oil inlet and of the air entering the air inlet.
