Abstract: A cast cylinder head having a port lined with an insulating sleeve is provided. The insulating sleeve includes an inner sleeve disposed within an outer sleeve defining an insulating gap between the inner sleeve and outer sleeve. The inner sleeve includes an inlet flange surface and an outlet flange surface joined to an inlet flange surface and an outlet flange surface of the outer sleeve, thereby providing a sealed insulating gap. The insulating gap may contain an insulating material or a vacuum. The outer sleeve includes an exterior surface onto which a molten metal is casted to form the cast cylinder. The exterior surface of the outer-sleeve includes a shoulder to fix the insulating sleeve within a fixed predetermined position within the casting.

Abstract: An internal combustion engine includes a cylinder block made of a first material having a plurality of cylinders and an insert made of a second material having a greater stiffness and a lower thermal coefficient of expansion than the first material and casted-in-place into the cylinder block. For each cylinder of the cylinder block, the insert includes a bolted anchor having a first threaded bore suitable to be engaged by an head bolt for fixing a cylinder head to the cylinder block, and a second threaded bore suitable to be engaged by a cap bolt for fixing a main bearing cap to the cylinder block, and a lubrication gallery connected to a plurality of the anchors.

Abstract: An internal combustion engine includes, but is not limited to an engine block, a crankshaft associated to the engine block, a cylinder head fixed on top of the engine block so as to define an assembly axis of the internal combustion engine, a camshaft, and a housing for a timing device connecting the crankshaft to the camshaft, the housing having a frontal opening which is laterally delimited by two opposite sidewalls belonging to the engine block and two opposite sidewalls belonging to the cylinder head, the frontal opening being closed with a first cover fixed to the sidewalls of the engine block, and with a second cover fixed to the sidewalls of the cylinder head.

Abstract: A turbocharger for an internal combustion engine, comprising a bearing housing, a rotating shaft coupled to the bearing housing, a compressor wheel mounted at one end of the rotating shaft, a compressor housing accommodating the compressor wheel and provided with an inlet and an outlet for an air stream, a turbine wheel mounted at the opposite end of the rotating shaft, and a turbine housing accommodating the turbine wheel and provided with an inlet and an outlet for an exhaust gas stream, wherein the bearing housing comprises a fastening flange suitable to be fixed to a component of the internal combustion engine, wherein the turbine housing is provided with a connecting pipe for fluidly connecting the turbine housing inlet with an exhaust manifold of the internal combustion engine, and wherein the connecting pipe includes means, for compensating axial thermal deformations thereof.

Abstract: In an intake arrangement for a combustion chamber in which a first intake duct produces a substantially rotational flow in the chamber, the flow from a second intake duct is divided into two components. The first component is an axial flow into the chamber and the second component is a rotational flow having the same sense of rotation as the first duct. The first and second components arise from the shaping of a junction region between branches of the second intake duct adjacent the chamber.

Abstract: A cooling system is provided for an internal combustion engine that includes, but is not limited to an engine coolant circuit having a coolant inlet and a coolant outlet, a radiator having an inlet and an outlet, a first pipeline for hydraulically connecting the radiator outlet and the engine coolant inlet, a second pipeline for hydraulically connecting the engine coolant outlet to the radiator inlet, a coolant pump located in the first pipeline for moving a coolant towards the engine coolant inlet, a thermostatic valve located in the first pipeline between the primary pump and the radiator outlet, for closing or at least partially opening the passageway, a bypass pipeline for hydraulically connecting an intermediate point of the second pipeline to an intermediate point of the first pipeline, the latter being located between the thermostatic valve and the radiator outlet, an exhaust gas recirculation cooler located in the bypass pipeline, an auxiliary coolant pump located in the bypass pipeline, and a control
