摘要:
The invention relates to a method for increasing the torque of a reciprocating piston internal combustion engine, especially a diesel engine (1), which comprises at least one cylinder (20), one turbine (3), one compressor (4), one charge air compressor (11), one first and second storage device (10, 14), one intercooler (5) in an intercooler line (6), one air drier (13), one feed valve (15) and one control device (16). Said method is characterized by the following steps: compressing air from a charge air line (6) or from a second air inlet (31) by means of the charge air compressor (11), storing the air compressed by the charge air compressor (11) in a storage device (10, 14); and blowing, in a clocked manner, blow air (25) which is stored as compressed air in a storage device (10, 14) into the cylinder (20) through an inlet valve (21) of the cylinder (20), thereby increasing the torque of the engine (1). The invention also relates to a device for carrying out said method.

The invention relates to a drive train (30) for a compressor (12) and a hydraulic pump (24) of a motor vehicle that, for assisting steering, has a hydraulic power steering (14) and an electric superimposed steering system (36). The compressor (12) and the hydraulic pump (24) are driven by a common output shaft (30) of a motor vehicle driving motor (16). According to the invention, means (10, 20) are provided that reduce the power delivered via the output shaft (30) to the compressor (12) and the hydraulic pump (24) when the demands upon the compressor (12) and upon the power steering system (36) allow this to occur. The invention also relates to a method for driving a compressor and a hydraulic pump of a motor vehicle that, for assisting steering, has a hydraulic power steering as well as an electric superimposed steering system.

The invention relates to a compressor system (10) for a vehicle (12), having a compressor (16) being driven by a drive motor (14) of the vehicle (12), and a suction air guide (18) for supplying air that has already been pre-compressed by a turbocharger (20) of the drive motor (14) to the compressor (16). The invention provides that means (22) are disposed in the suction air guide (18) for reducing the flow cross-section (24), said means able to limit the charging pressure of the already pre-compressed air supplied to the compressor (16). The invention further relates to a method for controlling a compressor system (10) comprising a turbocharged compressor (16).

A device and method for supplying fresh air to a turbocharged piston internal combustion engine are described. According to the invention, a fresh gas line section of an intake manifold has an adjustable flap, and inlet and outlet ports. An adjustment device is coupled to the flap for adjusting the flap. A compressed air port having an opening leading into a chamber of the fresh gas line between the flap and the outlet is provided, and a quantity regulating device with a valve to control the compressed air is also provided. An electronic control unit controls the quantity regulating device and the adjustable flap, so that the fully opened position of the flap corresponds to a fully blocked position of the quantity regulating device.

The invention relates to a fresh gas supply device (20) for an internal combustion engine (1) having a exhaust gas turbocharger (2), said device comprising a charge air inlet (9) for taking in a compressed charge air flow (28) from the exhaust gas turbo charger (2); an outlet (10) which is connected to the charge air inlet (9) via a valve section (17), said valve section (17) being closed in a closed position by at least one flap valve (23) which can be pivoted, preferably, about a flap rotational axis (24); an adjusting device (22) which is coupled to the at least one flap valve (23) for adjusting the same in the closing direction; and a compressed air inlet (11) for taking in compressed air into the outlet (10). Said compressed air inlet (11) is arranged such that the compressed air is directed into a compressed air flow (30) in the direction of the valve section (17) to the at least one flap valve (23). The invention also relates to a corresponding method for operating said fresh gas supply device (20).
