Abstract: An engine system of the present disclosure includes an engine configured to drive a plurality of pistons by burning a mixture of air and gas, an air supply pipe through which the air supplied to the engine flows, a supercharger configured to compress the air flowing through the air supply pipe, a gas supply pipe through which the gas supplied to the engine flows, and a mixer configured to mix the air that has passed through the supercharger and the gas. The mixer has a venturi tube shape in which a cross-sectional area of a flow path decreases and expands in a flow direction of the air that has passed through the supercharger, and the gas supply pipe is connected to a portion of the mixer where the cross-sectional area of the flow path in the mixer is decreased.
