A cylinder block that can be used commonly in a longitudinally mounted engine and a transversely mounted engine without increasing a manufacturing cost. The cylinder block comprises an attachment flange joined to a transmission or a transaxle, and an oil pan or the oil pan and a ladder frame are attached to a lower end thereof. The attachment flange comprises: a first flange formed on an outer periphery thereof; a first joint surface formed on the first flange to be joined to a matching surface of the transmission; a second flange extending in the inner side of the first flange; and a second joint surface formed on the second flange to be joined to a matching surface of the transaxle.

Engines operating using multiple, different types of fuel are described. The engines may include components that control the introduction of fuels and/or reduce premature pre-ignition of fuels, such as a fuel comprising a percentage of hydrogen. The described hydrogen-fueled engines have a reduced carbon footprint.

An internal combustion engine system including a cylinder block, a cylinder head attached to the cylinder block, an EGR cooler, and a coolant collector bracket is provided. The cylinder head includes a plurality of coolant passages. The coolant collector bracket is coupled to and between the cylinder head and the EGR cooler. The coolant collector bracket includes a plurality of coolant inlets directly coupled to a plurality of outlets of the plurality of coolant passages of the cylinder head. The coolant collector bracket also includes an EGR coolant outlet directly coupled to an inlet of the EGR cooler. The coolant collector bracket also includes an EGR cooler inlet directly coupled to an outlet of the EGR cooler.

An internal combustion engine and a head gasket are provided. The internal combustion engine includes a block having at least one cylinder, a head joined to the block at a head interface, a cooling fluid circulation passage extending at least partially through the head and the block and having a first portion disposed in the head and a second portion disposed in the block, a head gasket having a plate extending across the head interface and separating the first portion of the cooling fluid circulation passage from the second portion of the cooling fluid circulation passage, and a plurality of orifices extending through the plate. The plurality of orifices is aligned with the cooling fluid circulation passage and is configured to control a flow of cooling fluid circulating between the first portion of the cooling fluid circulation passage and the second portion of the cooling fluid circulation passage.

A method is for generating a cylinder crankcase including a foreign object inclusion for cast reduction and for the improved cleanliness of the generated component. The cast material is in particular removed or pushed from the areas between the tie-rods (2) below the water jacket (1), to avoid dirt input into the component during later engine operation. The areas below the water jacket (1) between the tie-rods (2) are designed as a separate tie-rod core (3), and the bolts (4) used during later installation at the water jacket core (5) are enclosed in the tie-rod core (3), so that the tie-rod core (3) is completely surrounded by cast material in the component following the cast and the bolt (4) has coalesced with the cast, and the tie-rod core (3) remains in the generated component and is located in an encapsulated space generated by the cast material.

An engine block formed according to a method that includes forming an insert, coating the insert with a bond material, placing the insert within a casting mold or die, purging the casting mold or die with an inert gas, filling the casting mold or die with molten metal to encapsulate the insert, diffusion bonding the molten metal to the insert to form a diffusion bonded insert, placing the diffusion bonded insert within a cavity of a secondary casting mold or die, filling the secondary casting mold or die with molten metal to form an engine block composite casting assembly, and casting and heat treating the engine block composite casting assembly is provided. The insert can be free of serrations for mechanical coupling between the insert and the engine block.

In an internal combustion engine that includes a cylinder block and a cylinder head, and has a cam chain chamber on a side of the cylinder block, a beam member that traverses the cam chain chamber is disposed in the cam chain chamber.

An internal combustion engine system including a cylinder block, a cylinder head attached to the cylinder block, an EGR cooler, and a coolant collector bracket is provided. The cylinder head includes a plurality of coolant passages. The coolant collector bracket is coupled to and between the cylinder head and the EGR cooler. The coolant collector bracket includes a plurality of coolant inlets directly coupled to a plurality of outlets of the plurality of coolant passages of the cylinder head. The coolant collector bracket also includes an EGR coolant outlet directly coupled to an inlet of the EGR cooler. The coolant collector bracket also includes an EGR cooler inlet directly coupled to an outlet of the EGR cooler.

An insert for a bed plate according to an embodiment of the present disclosure is coupled to a lower portion of an engine block. The insert of the bed plate includes a crankshaft seating portion disposed at a center and where a crankshaft is mounted. The insert of the bed plate also includes a ladder frame fixing portions that are disposed at opposite ends of the insert to facilitate coupling to a ladder frame. The insert of the bed plate also includes a plurality of protrusion portions that are formed on both surfaces of the insert and contact the ladder frame.
