Abstract
In an engine system with a reformer being installed in an exhaust pipe to reform a fuel, a control valve for controlling a flow rate of exhaust gas is provided downstream from an installed position of the reformer in the exhaust pipe. In the engine system with the reformer, since a part of the exhaust gas can be trapped in a space between the reformer and an engine chamber by closing the control valve during an exhaust stroke, the reforming efficiency of the reformer can be heightened.
