Abstract: A system and methods are provided to deactivate a cam driven fuel pump. The system comprises a direct fuel injection system; a port fuel injection system; a pump for the direct injection system driven by a cam, wherein the pump can be activated and deactivated as a function of the activation of the direct injection system. Deactivating a pump when no fuel is pumped through it minimizes wear on pump components and increases efficiency.

Abstract: An internal combustion engine is disclosed that has a cylinder block with multiple cylinders, a bridge between adjacent cylinders, a cooling slot in the bridge, and a water jacket portion in the cylinder block. A cylinder head is coupled to the cylinder block which has a first cooling passage fluidly coupling the cooling slot and the water jacket portion in the cylinder block, a water jacket portion in the cylinder head, and a second cooling passage in the cylinder head fluidly coupling the cooling slot with the water jacket portion in the cylinder head. A cylinder head gasket is arranged between the cylinder head and the cylinder block which has a first orifice in the cylinder head gasket cooperating with the first cooling passage a second orifice in the cylinder head gasket cooperating with the second cooling passage.

Abstract: Systems and methods for a turbocharged internal combustion engine are provided herein. One example system includes a cylinder head with at least two cylinders, at least two exhaust openings per cylinder, at least one of which is engageable. The system further includes a first exhaust manifold integrated in the cylinder head and connecting the engageable openings with a first turbocharger turbine, and a second, separate exhaust manifold integrated in the cylinder head and connecting the non-engageable openings with a second turbocharger turbine in parallel with the first turbine.

Abstract: A supercharged internal combustion engine having at least two exhaust-gas turbochargers is provided. The engine includes a first exhaust manifold and a second exhaust manifold which are permanently connected to one another upstream of the two turbines of the turbochargers via at least one connecting duct which cannot be closed off. In this way, overflow of exhaust from the one exhaust manifold may be transferred to the other exhaust manifold.

Abstract: Embodiments for a turbocharged engine including two turbochargers are provided. In one example, a turbocharger engine includes two turbochargers arranged in parallel, each coupled to a separate exhaust manifold. Bypass of exhaust around both turbochargers may be provided via a single wastegate.

Abstract: A cylinder head has at least three cylinders each coupled to at least one exhaust port, individual exhaust ducts coupled to each of the exhaust ports, and a combined exhaust duct coupling all individual exhaust ducts. The combined exhaust duct emerges from the cylinder head at a location displaced longitudinally from a center of the cylinder head.

Abstract: Example embodiments for reducing thermal load in one or more exhaust gas lines are provided. One embodiment includes an internal combustion engine with liquid cooling, comprising at least one exhaust gas line, at least one coolant jacket, and a common boundary wall separating the at least one exhaust gas line and the at least one coolant jacket, wherein the common boundary wall includes a surface structure provided on sides of the coolant jacket in at least one locally limited region. In this way, the surface structure on the sides of the coolant jacket may increase heat transfer to reduce thermal loading.

Abstract: The disclosure relates to an internal combustion engine with a cooling circuit having a water jacket portion in the cylinder block and a water jacket portion in the cylinder head which has an intake portion and an exhaust portion. Flow from the intake and exhaust portions mix in an outlet housing which has a cylinder head outlet thermostat. A coolant pump provides flow to a first branch to the exhaust portion and a second branch to the water jacket portion in the cylinder block. A block thermostat is located in the second branch downstream of the coolant pump and upstream of the water jacket portion in the cylinder block. The intake portion of the water jacket portion in the cylinder head is fluidly coupled to the water jacket portion in the cylinder block.

Abstract: The invention relates to a piston pump for increasing pressure for liquids, in particular for the camshaft phase adjustment of reciprocating internal combustion engines, said piston pump advantageously being integrated into the housing of the cylinder head. The piston pump for increasing pressure is defined in that it increases an existing fluid pressure to a required fluid pressure and keeps this pressure virtually constant. The piston pump for increasing pressure is advantageously pre-assembled in a sleeve.

Abstract: The invention relates to a longitudinally adjustable connecting rod (1), in which a piston part (2) and a shaft part (9) are telescopically inserted one inside the other. Piston part and shaft part can be locked together at certain lengths by pins (5a, 5a′, 5b, 5b′) supported in the piston part skirt (8), which engage in associated recesses (4a, 4a′, 4b, 4b′) on the shaft part skirt (3). Every two pins (5a, 5a′; 5b, 5b′) are pushed apart by springs (11a, 11b) situated between them. Through corresponding feed ducts (7a) a hydraulic medium can be purposely delivered to the recesses in the piston part skirt (3), in order to push pins situated therein back into the shaft part skirt (8).
