Compressor system, and method for the operation of a compressor system

Abstract

The invention relates to a compressor system (10) comprising a compressor (12) for supplying compressed air to a utility vehicle (14) that has a driving engine (18) with a turbocharger (16). Air that is pre-compressed by the turbocharger (16) can be sucked in by the compressor (12) via a first air supply pipe (20). According to the invention, ambient air that is not pre-compressed can be sucked in by the compressor (12) via a second air supply pipe (12). The invention further relates to a method for controlling a compressor system (10) comprising a compressor (12) for supplying compressed air to a utility vehicle (14) that has a driving engine (18) with a turbocharger (16).

Description

technical field

[0001] The invention relates to a compressor system with a compressor for supplying compressed air to a cargo vehicle with a drive engine with a turbocharger, wherein the air precompressed by the turbocharger can be conveyed via a first air The pipeline is sucked by the compressor.

[0002] Furthermore, the invention relates to a method for controlling a compressor system with a compressor for supplying compressed air to a goods vehicle with a drive engine with a turbocharger. Background technique

[0003] Modern cargo vehicles often have subsystems that operate on compressed air, such as service brakes and air springs that operate on compressed air. In order to be able to supply sufficient compressed air to subsystems of the truck that are operated with compressed air, the truck also has a compressor for generating compressed air.

[0004] Turbocharged single-stage and naturally aspirated single-stage compressors are used today. The advantage of the press...

The illustrated truck 14 includes, in addition to the drive engine 18 and the compressor system 10 , a compressed air treatment unit 58 with a user; an air filter 52 ; a charge air cooler 54 and a turbocharger 16 . The compressor system 10 itself comprises, in addition to the compressor 12, which may be a single-cylinder or twin-cylinder compressor: an electronic control unit 34 with an interface 36 on a CAN bus 38; with a charge air valve arranged therein a first air delivery line 20 of the device 24; and a second air delivery line 22 having an ambient air-valve arrangement 26 disposed therein. Furthermore, a pressure sensor 28 is arranged in the first air supply line 20 , which determines the boost pressure provided by the turbocharger 16 upstream of the charge air valve arrangement 24 .
