  • Patent number: 8061309
    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.

  • Patent number: 7721683
    Abstract: The invention relates to a cooling strategy for an internal combustion engine (1) which has at least one cylinder head (2) and an associated cylinder block (3). A coolant flows in a coolant circuit (4), with at least one control element (6, 7, 8, 9) being assigned to the coolant circuit (4). During a warmup of the internal combustion engine, in successive phases, the coolant flow is conducted to separate cooling regions by the control elements (6, 7, 8, 9), wherein in an operating mode at operating temperature which follows the warmup, the coolant flow is conducted to separate cooling regions by the control elements (6, 7, 8, 9) taking into consideration the operating states of the internal combustion engine.

  • Patent number: 7201118
    Abstract: The invention relates to an internal combustion engine having a piston-cooling arrangement (1) which has at least one spray device (2, 27; 2, 39) which is supplied with a coolant/lubricant via at least one supply passageway (3). The supply passageway (3) is arranged in a module (4) composed of a crankshaft-bearing structural element (6) and a crankshaft-bearing cap (7). The spray device (2, 27; 2, 39) is coupled to the crankshaft-bearing cap (7), a crankshaft-bearing shell (14) in the region of the supply passageway (3). Supply passageway (3) also connect to through-opening (16), so that coolant/lubricant can be directed via the supply passageway (3) to both the spray device (2, 27; 2, 39) and a crankshaft (17). The spray device (2) is designed as an oil-spray nozzle (27) or alternatively as a spray hole (39) integrated in the crankshaft-bearing cap (7).

  • Patent number: 6532934
    Abstract: The invention relates to a control process for charge flow management devices as arranged in the intake area of the inlet ports of direct-injection internal combustion engines and port-injection type internal combustion engines having intake ports into which no fuel is injected. The process is characterized by the fact that the charge flow management devices are not closed when the engine operates on overrun. This reduces fouling on the intake valves produced by fuel and lubricant residue.
