Air pollution system temperature control
Abstract
Abstract A METHOD AND APPARATUS ARE PROVIDED FOR MAINTAINING THE TEMPERATURE OF HOT GASES BEING EXHAUSTED FROM AN INTERNAL COMBUSTION ENGINE WITHIN A CONTROLLED RANGE FOR ASSURING A MAXIMIZED THERMAL REACTING OF HYDROCARBONS AND CARBON MONOXIDE WITH A MINIMIZED PRODUCTION OF NITROGEN OXIDES BEFORE DISCHARGE INTO THE ATMOSPHERE. THE METHOD AND APPARATUS EMPLOY FLUID-JACKETING OF AN EXHAUST MANIFOLD AND A VALVE SYSTEM OPERATIVELY-CONNECTED BETWEEN THE JACKETING AND AN INTAKE MANIFOLD TO SUPPLY AIR TO THE JACKETING TO REDUCE THE TEMPERATURE OF THE EXHAUST GASES WHEN THE ENGINE IS OPERATING UNDER FULL OR HEAVY LOAD AND TO WITHDRAW AIR AND PROVIDE A MAXIMIZED INSULATING EFFECT WHEN THE ENGINE IS OPERATING UNDER A LOW LOAD OR IS IDLING.
