Abstract: Systems and methods for controlling shut down of a multiple cylinder internal combustion engine include a mechanical energy storage device to decelerate an engine crankshaft to a stopping position desirable for restarting of the engine. Energy stored during shut down may be used to adjust or reposition the crankshaft to one of a plurality of angular orientations advantageous for restarting, and/or used to rotate the crankshaft during restarting of the engine. A flywheel having a variable mass, such as provided by two or more segments, which may be fixedly or selectively coupled to one or more springs may be used to selectively store and release energy.

Abstract: An internal combustion engine with a dry sump lubrication system is disclosed. The dry sump lubrication system has an oil pan coupled to the engine, an oil reservoir, an oil discharge tube coupling between the oil pan to the oil reservoir, an oil supply tube coupling the oil reservoir to the engine, and a vent tube coupling the oil reservoir to the intake manifold. The dry sump lubrication system may have a fresh air tube coupled to the oil reservoir. A control element coupled to an upstream side of the fresh air tube controls fresh air supplied to the oil reservoir. The oil reservoir may be insulated to retain energy in the oil during short shutdown periods. The oil reservoir may have a heat exchanger which allows engine coolant to flow through the heat exchanger.

Abstract: The present invention relates to a transducer for surface acoustic waves, in particular the present invention relates to a resonator and a filter for surface acoustic waves on basis of the transducer according to the present invention. The object of the present invention is to propose a transducer for surface acoustic waves which is composed of cells containing two electrode fingers per cell, wherein the transducer according to the present invention shows unidirectional behaviour for propagation directions of the surface acoustic waves parallel to highly symmetrical directions of the crystal substrate.

Abstract: The invention relates to a split cooling circuit (16) of an internal combustion engine (17), with a cylinder head water jacket (18) and an engine block water jacket (19) being provided. The split cooling circuit (16) has a pump (21), a radiator (22), a thermostat (23) and a heater core (24), with a coolant circulating in the split cooling circuit (16). To considerably reduce a warm-up phase of the internal combustion engine, the thermostat (23) is arranged to simultaneously control a flow of the coolant through the engine block water jacket (19) and through the radiator (22) when the coolant exceeds a predetermined temperature.

Abstract: Systems and methods for controlling stopping position of a crankshaft during shutdown of a multiple cylinder internal combustion engine influence cylinder pressure independent of associated intake/exhaust valves during shutdown of the engine so the crankshaft stops in a position favorable for restarting. Embodiments include an engine having variable compression ratio cylinders with the compression ratio of the cylinders controlled to vary cylinder pressure during shutdown to control stopping position of the crankshaft, or an auxiliary control valve disposed in a cylinder wall to control pressure within the cylinders during shutdown so the crankshaft stops in a position desirable for restarting.

Abstract: Systems and methods for controlling stopping position of a crankshaft during shutdown of an internal combustion engine control a fluid pressure to control a corresponding drive torque of a fluid pump. Kinetic energy of the engine at shutdown may be used to control fluid pressure in a power steering system or fuel injection system to stop the crankshaft in a position favorable for restarting.

Abstract: In a device for mounting an engine bearing of an internal combustion engine, a bracket is provided for attachment to an end face of a cylinder head of the internal combustion engine. The bracket includes a contact area to rest against the end face of the cylinder head, and further includes an angular component with a first arm as the mounting for the engine bearing and a second arm, formed integrally therewith, as an auxiliary unit carrier, thereby forming an engine bearing console with an integrated auxiliary unit carrier. In a further embodiment an eyelet-shaped engine lifting device is formed integrally therewith, preferably in the vicinity of the auxiliary unit carrier. Similarly, a mounting point for securing a guide pulley for the auxiliary unit may be integrated in a thickened front region of the component.

Abstract: In a radio system which operates using code division multiplex (CDMA) the interference in the training sequences, for example interblock sequences, of all the K subscribers in the received signal is overcome before data detection at the receiving end. The interference in the training sequences of all K subscribers is modeled using the estimated channel pulse responses and, finally, is subtracted from the received signal. The method and apparatus can be used in CDMA mobile radio systems, in particular with joint detection.
