Abstract
A compressor system includes a compressor for supplying compressed air to a commercial vehicle that has an engine with a turbocharger. Air that is pre-compressed by the turbocharger can be sucked in by the compressor via a first air supply pipe. Ambient air that is not pre-compressed can be sucked in by the compressor via a second air supply pipe. A method operates the compressor system including the compressor for supplying the compressed air to the commercial vehicle that has the engine with the turbocharger accordingly.
Claims11
A compressor system for use in a commercial vehicle having an engine with a turbocharger, the compressor system comprising:
- a compressor for supplying compressed air to the commercial vehicle;
- a first air feed through which air precompressed by the turbocharger is capable of being sucked-in by the compressor;
- a second air feed through which non-precompressed ambient air is capable of being sucked-in by the compressor;
- a charge-air valve device operatively arranged in the first air feed;
- an ambient-air valve device operatively arranged in the second air feed;
- and
- a pressure sensor operatively arranged in the first air feed, the pressure sensor determining a boost pressure provided by the turbocharger,
- wherein the charge-air valve device is arranged to allow sucking-in precompressed air provided by the turbo-charger only when the boost pressure provided by the turbo charger lies below an adjustable boost pressure threshold;
- and
- wherein the ambient-air valve device is arranged to allow sucking-in ambient air only when the boost pressure provided by the turbocharger overshoots said adjustable boost pressure threshold.
A method of operating a compressor system having a compressor for supplying compressed air to a commercial vehicle with an engine having a turbo charger, the method comprising the acts of:
- sucking-in to the compressor via a first air feed precompressed air provided by the turbocharger below an adjustable boost-pressure threshold;
- sucking-in to the compressor via a second air feed non-precompressed ambient air above the adjustable boost-pressure threshold;
- wherein below the adjustable boost-pressure threshold, an ambient-air valve device closes the second air feed;
- and
- wherein above the adjustable boost-pressure threshold, a charge-air valve device closes the first air feed.
A method of operating a compressor system in a commercial vehicle having an engine with a turbocharger, the method comprising the acts of:
- monitoring boost-pressure from the turbocharger;
- feeding precompressed air from the turbocharger to the compressor via a first air feed only when the boost-pressure is below an adjustable boost-pressure threshold;
- and
- feeding non-precompressed ambient air to the compressor via a second air feed only when the boost-pressure is above the adjustable boost-pressure threshold.
