via conductors 150 follows in part two separate paths initially and a combined path finally these paths include the path defined by conductor 210 and 220 and 230 on the one hand thence through the carburetor connector 232 by means of the supplemental connector 240 emanating from the chamber heat from the generator is adapted to pass into a supplemental fuel heating system 224 thence via conductor 236 leaving exposed the fuel line 226 and joining the connector 232 which is selectively valve controlled by the valve 234 as shown the sources of heat from the heat generator 100 to the fuel line are therefore two in number and comprise initially conductors 210 and 240 said conductors combining immediately adjacent valve 234 to feed into the connector 232 at the base of the carburetor 130 this system may be adapted to a conventional internal combustion engine carburetor or to a modified post carburetion system hereinafter described optionally the carburetor 130 is shown to be disposed in connection with input gasification chamber 120 which said chamber has connection via the trap 140 with the outlet chamber 122 whereby the gasified fuel from the carburetor may pass through said trap for entrapping ungasified liquids by reference to the elements 170 and 180 having connection with exhaust 118 it will be appreciated that as in my patent application ser no 393 629 now u s pat no 3 911 881 aforesaid a blower system 170 may be selectively actuated by throttle position or engine speed to create desired backpressure to the.
