Estimating the term…
The invention relates to a system for charge air cooling for an internal combustion engine based on an engine family, wherein an intake module is arranged between a throttle valve and a combustion chamber. A first cooling device of the system is shaped to be structurally integrated into the intake module. Furthermore, in accordance with the system, a second cooling device is available, which supplements the first cooling device and which is designed to pre-cool charge air before said charge air enters the intake module and which is adapted for use with at least one engine model of the engine family. The second cooling device is intended for top engine types and can be arranged between the throttle valve and a charge air compressor.
A system for charge-air cooling for an internal combustion engine which is based on an engine family and in which an intake module is arranged between a throttle flap and a combustion chamber, wherein a first cooling device of the system is designed to be structurally integrated into the intake module, and in which a charge-air line is arranged between a charge-air compressor and the throttle flap, wherein, in the system, a second cooling device is provided which supplements the first cooling device, is designed to precool charge air before it enters the intake module and is adapted for use with at least one engine model of the engine family, which second cooling device can be arranged between the throttle flap and the charge-air compressor.
A method for providing charge-air cooling for motor vehicles with an internal combustion engine, wherein, for charge-air cooling for an engine family, use is made of a system that can be adapted for multi-stage, preferably two-stage, charge-air cooling, wherein, regardless of the respective engine model of the engine family, a first cooling device is arranged in an intake module arranged between a throttle flap and a combustion chamber, and in the case of one or more engine models of the engine family, a second cooling device is additionally arranged between the throttle flap and a charge-air compressor, such that precooling of charge air before it enters the intake module can be performed there.
An internal combustion engine having a charge-air compression unit, which internal combustion engine is based on an engine family and in which internal combustion engine a first cooling device for charge-air cooling is arranged in the intake tract downstream of a throttle flap, wherein, furthermore, a second cooling device for precooling the charge air is arranged upstream of the throttle flap and preferably downstream of a charge-air compressor.
