A generally sealed, thermally insulated diffusion chamber is coupled via a capillary tube to the fuel bowl of an automotive internal combustion engine with the capillary tube terminating at the upstream end of the diffusion chamber in a fuel jet nozzle which directs fuel into a venturi leading into the diffusion chamber. A plurality of small air inlet holes upstream of the venturi intersects the fuel leaving the jet nozzle to effect a low temperature thermally and molecularly changed air fuel mixture which is highly diffused and which is delivered by means of insulated tubing from the diffusion chamber to the intake manifold downstream of the carburetor under a delayed or partially retained action, greatly reducing exhaust emissions, especially during deceleration of the vehicle.
