  • Publication number: 20240125282
    Abstract: An internal combustion engine includes a crankcase for rotatably supporting a crankshaft about a crankshaft longitudinal axis. The crankcase comprises a crankcase water jacket, a cylinder head which is connected to the crankcase and comprises a cylinder head water jacket, and a coolant pump for supplying the crankcase water jacket and the cylinder head water jacket with a coolant volume flow. The crankcase water jacket and the cylinder head water jacket are fluidly connected to one another in series. The crankcase water jacket is suppliable with the coolant volume flow by the coolant pump via a crankcase inlet, and the crankcase water jacket is designed such that the coolant volume flow is directed via a crankcase outlet and is transferred in the direction of the cylinder head water jacket. The crankcase inlet and the crankcase outlet are axially spaced apart. The crankcase inlet is arranged on a first longitudinal side of the crankcase.

  • Publication number: 20240084729
    Abstract: An internal combustion engine including a cylinder crankcase and a cylinder head with an integrated height-adjustable fan attachment for elastic V-ribbed belts. 2. An internal combustion engine including a crankcase (1), at least one device for driving a fan, in particular of a vehicle, in particular a commercial vehicle, is described. The internal combustion engine includes a fan bracket (3) and a bearing device (5) via which the fan is displaceably situated relative to the crankshaft of an internal combustion engine of the drive unit; and a belt drive via which the fan is drivable, including a first belt pulley and a second belt pulley which are in drive connection via a belt (8), the first belt pulley being situated on the bearing device (5).

  • Patent number: 11493004
    Abstract: An internal combustion engine including a crankcase (1) and including a cylinder head is described, including at least one cylinder block, at least one planar flange surface for accommodating at least one cooler (2), at least one cooler (2), at least one coolant inlet to the cooler (2), at least one coolant outlet (8) from the cooler (2), at least one exhaust gas inlet to the cooler (2), at least one integrated exhaust gas feedthrough from the cooler (2), and at least one internal cooling section (3).

  • Patent number: 11473523
    Abstract: 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.
