Fuel distribution insert for internal combustion engine

摘要

An injection-molded, plastic fuel distribution insert for an internal combustion engine having a wet manifold promotes complete fuel atomization and vaporization. The fuel distribution insert also provides for even fuel distribution to the various combustion chambers. The fuel distribution insert preferably has a flange integral with one or more downwardly extending shrouds. Each shroud defines a subchamber having a volume substantially less then the volume of the manifold plenum. A fuel-air mixture from a fuel-air supply source enters into the shroud at the inlet of the intake manifold and is retained within the shroud until the mixture exits one or more exit windows in the shroud. The exit windows in the shroud are placed to promote even fuel distribution.
