ABSTRACT:
A carburetion system, without complicated control systems, functions uniformly throughout the range of engine load and incremental increases of power demand to provide efficient stable engine performance for a natural gas fired, internal combustion engine using EGR. A cogeneration system for supplying distributed generation of electricity and process/utility heat, employs a system for engine cooling and effective heat transfer to a cogeneration client, reduces engine head temperature, thereby reducing fuel consumption and reducing pollutants, as well as delivering substantially increased heat to a cogeneration process/utility heat facility by use of a carburetion system which employs at least a pair of spaced apart venturi positioned in series proximate one to another such that a first exhaust recycled gas venturi is upstream of a fuel venturi where fuel and air/exhaust gas are admixed prior to the resultant gas being introduced into a turbocharger. The distance between the exhaust venturi and fuel venturi is affective to provide a given amount of exhaust gas to air ratio prior to entering the fuel venturi inlet. Unexpectedly the spatial relationship between the two venturi, one to the other, affectively regulates exhaust gas air mixture, as well as the air/fuel/exhaust gas mixture to the engine by means solely of pressure increase and decrease (vacuum) of the engine intake system.
