ENGINE SYSTEM PROVIDED WITH INTAKE BYPASS DEVICE

摘要

An object is to provide an engine system including an intake bypass device whereby it is possible to expand the operation range of a compressor without causing the output of a turbine to become insufficient. An engine system (1) includes an intake bypass device (20) including a bypass channel (14) connecting a downstream side of a compressor (10) of a turbocharger (12) in an intake channel (4) and an upstream side of a turbine (8) of the turbocharger (12) in an exhaust channel (6), a bypass valve (16) disposed in the bypass channel and configured to control a flow of compressed intake air in the bypass channel (14), and a heating unit (18) for heating the compressed intake air flowing through the bypass channel.
