PROBLEM TO BE SOLVED: To ensure combustion stability in a normal cylinder by adjusting content ratio of combustion promotive gas to a modified gas amount, even in a case where the modified gas amount from a modified cylinder to the normal cylinder sufficiently increases.SOLUTION: An engine system includes: a first fuel supply unit configured to supply fuel F guided to normal cylinders 40a, 40b, 40c and a modified cylinder 40d; a second fuel supply unit configured to supply fuel F guided to the modified cylinder 40d and provided separately from the first fuel supply unit; second fuel supply amount adjustment means of adjusting a supply amount of fuel F of the second fuel supply unit so that an excess air ratio of air fuel mixture M in the modified cylinder 40d is 1 or less; and air fuel mixture temperature control means of controlling temperature of the air fuel mixture M circulating through a suction branch pipe 20d for modified cylinder branched from a suction main pipe 20 and connected to the modified cylinder 40d.SELECTED DRAWING: Figure 1 |
