More Information
Summary:A low pressure fuel stream is injected into a carburetor by way of a fuel tube injector combination having an insulating air space provided between the internal flow path structure and the outer surface of the combination which is exposed to relatively high temperatures. The fluid stream is thus maintained at a relatively low temperature and pressure until it is discharged from the fuel injector, at which time a surrounding airstream prevents the direct contact of the fuel flow with the surface of the fuel injector, and therefore prevents any carbon build-up which would otherwise occur on or near the fuel exit orifice.
