Title: ENGINE SYSTEM AND CONTROL METHOD
Abstract:
An engine system according to one embodiment of the present invention is provided with: an air cooler for cooling fresh air provided to a scavenging flow channel; a scrubber for cleaning, with a cleaning fluid, EGR gas provided to an EGR flow channel; an EGR gas cooler for cooling the EGR gas provided to the EGR flow channel; and a control unit for controlling the air cooler and/or the EGR gas cooler such that a non-condensed state is maintained in which the dew point temperature of the EGR gas supplied to the scavenging flow channel is lower than the temperature of the fresh air joining with the EGR gas, and lower than the temperature of the scavenging gas supplied to an engine main body.
