Abstract

A lobed exhaust diffuser apparatus, system, and method configured to cool exhaust gases from an internal combustion engine comprises a diffuser having a proximal end, configured to receive exhaust gases from the engine, and a distal end, configured to expel the exhaust gases into the atmosphere. A plurality of lobes are disposed on the distal end such that at least a portion of the exhaust gases pass through the lobes, increasing the interaction surface area between the exhaust gases and the atmosphere, allowing for more rapid diffusion and entrainment between exhaust gases and atmospheric gases, resulting in more rapid cooling of the exhaust gases.
