Abstract
An engine system with a reformer, wherein an unreformed fuel is reformed by the reformer mounted in an exhaust pipe, and wherein a reformed fuel containing hydrogen is supplied to an engine. The engine system with a reformer includes a controller which, when the hydrogen generated by the reformer is supplied to the engine, determines a target heat generation beginning timing in accordance with a load applied to an engine, an engine speed, and an air excess ratio of an air-fuel mixture, and which controls an ignition timing of the engine so that a difference between a current heat generation beginning timing and the target heat generation beginning timing of the engine is within a predetermined range.
