Abstract: According to the embodiments of the Eldridge ENJET—Engine Exhaust Jet Nozzle invention, the method and apparatus include an external plenum, support spool, fan, and nozzle assembly that is sleeved over and mounted at the discharge end of an internal combustion engine exhaust silencer or pipe for the purpose of creating a high volume and high velocity discharge capable of overcoming prevailing wind velocity to such an extent that a cylindrical air discharge pattern 50-100 feet away from the end of the apparatus nozzle provides increased dispersal and dilution of the engine exhaust gas. The invention is especially useful for accelerating the high temperature, low velocity, and toxic internal combustion engine exhaust gas away from human habitation or work areas.
