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…
