SYSTEM FOR ADDING GASEOUS MATERIALS TO COMBUSTION SYSTEM

摘要

There is disclosed a system for providing gaseous material to a combustion system comprising control means (50, 52) for detecting change of the rate of combustion in the system and for initiating admission of gaseous material into the system; and means (20) responsive to said control means for drawing gaseous material from a source of gaseous material and admitting the gaseous material into the system at a position downstream of a carburetor (44) in the system. There is also disclosed a method for providing gaseous material to a combustion system comprising detecting a change in the rate of combustion in the system and in response thereto admitting gaseous materials to the system at a position downstream of the carburetor (44).
