Abstract
A substantially Y shaped split intake manifold is disclosed and also a method of connecting this manifold having fuel-air outlet conduits to a plurality of internal combustion engine cylinder inlet ports. The method comprises the steps of applying a layer of high temperature resistant rubber sealant that remains flexible upon curing to the two outlet passages or conduits of the split intake manifold for forming gas-tight seals between the two outlet passages of the manifold and the associated two inlet ports of the two cylinders of the internal combustion engine and allowing the sealant to cure in situ to adhesively bond to the two outlet passages of the manifold.
Claims8
A manifold for a multi-cylinder internal combustion engine comprising a separate upper member and a separate lower member, each said member being so configured and constructed as to fit together in gas tight relationship and when so fitted together to define an inlet air-fuel mixture conduit constructed and configured for receiving a carburetor and two outlet air-fuel mixture conduits, said inlet conduit being in fluid communication with said outlet conduits, said outlet conduits being so disposed with respect to the inlet conduit and to each other as to permit said outlet conduits to be connected to separate internal combustion engine cylinder input ports for passing an air-fuel mixture from the carburetor to the separate internal combustion engine cylinder input ports of respective cylinders.
In a multi-cylinder internal combustion motorcycle engine having a manifold for passing an air-fuel mixture to cylinders of said engine, the improvement wherein the manifold comprises a separate upper member and a separate lower member, said members being so configured and constructed as to fit together in gas tight relationship and when so fitted together to define an inlet air-fuel mixture conduit constructed and configured for receiving a carburetor and outlet air-fuel mixture conduits, said inlet conduit being in fluid communication with said outlet conduits, said outlet conduits being so disposed with respect to the inlet conduit and to each other as to permit said outlet conduits to be connected to separate internal combustion engine cylinder input ports for passing an air-fuel mixture from the carburetor to the separate internal combustion engine cylinder input ports of respective cylinders.
A substantially Y shaped split intake manifold for an internal combustion engine comprising, in combination:
- a separate upper member and a separate lower member;
- input conduit means coupled to said upper member and said lower member for accepting an air-fuel mixture from a carburetor;
- plural output conduit means each coupled to said upper member and said lower member for receiving said air-fuel mixture from said input conduit means and for providing an equal amount of said air-fuel mixture to respective plural cylinders of said internal combustion engine.
