The present disclosure provides a recirculation device comprising a body comprising at least one first passage configured to receive an exhaust, at least one second passage configured to receive a fuel, at least one third passage configured to receive a mixture of the exhaust and the fuel, and a longitudinal axis extending from the second passage to the third passage. The device can also comprise a nozzle comprising an inner cavity for directing fuel towards an orifice, located at the smallest cross-sectional area of the inner cavity and a piston slideably located within the body comprising a first end configured to receive the fuel and a second end configured to fuel to the nozzle cavity, whereby the piston can be actuated along the longitudinal axis of the body by the exhaust controlling the flow of fuel passing through the orifice. A mixing chamber located within the body can be configured to receive an exhaust and configured to receive fuel from the orifice.
