Abstract
A water-alcohol injection apparatus for an internal combustion engine having a crankcase and a carburetor mounted on the air fuel manifold of the engine, the apparatus including a reservoir for a water-alcohol mixture, a main reservoir conduit connected to the reservoir, a first conduit connecting the main conduit to manifold to provide a continuous flow of the fluid mixture to the manifold, a second conduit connecting the main conduit to the carburetor to provide fluid mixture flow in response to demand and a third conduit connecting the crankcase to the first conduit, the third conduit including a pressure compensating valve to control the flow of crankcase emissions to the carburetor.
Claims5
An injection apparatus for injecting a fluid mixture of water and alcohol into a fuel distribution system for an internal combustion engine, the fuel distribution system including
- a carburetor having a throttle valve, the carburetor being connected to the intake manifold of an internal combustion engine which includes a crankcase,
- said apparatus comprising a reservoir for said fluid mixture,
- first conduit means connected to said manifold downstream from said throttle valve,
- second conduit means connected to said manifold upstream from said throttle valve,
- main passage means connecting said first and second conduit means to said reservoir,
- one way flow control means in said main passage means for controlling the flow of fluid mixture to the manifold,
- and a third conduit means connected between said first conduit means and the crankcase of the engine,
- said third conduit means including a pressure-compensating valve positioned to vent crankcase emissions to said first conduit means.
In an internal combustion engine having a crankcase and a carburetor connected to the crankcase through a manifold to the carburetor including a choke valve and a throttle valve located on each side of a venturi in an air fuel passage in the carburetor, an air flow filter connected to said carburetor, a water-alcohol injection apparatus comprising a reservoir for a water-alcohol fluid mixture, first conduit means connected to said manifold downstream from said throttle valve, second conduit means connected to said manifold upstream from said venturi and downstream from said choke valve, and third conduit means connected between said crankcase and said first conduit means;
- and main passage means connecting said first and second conduit means to said reservoir whereby said fluid mixture will normally flow through said main passage means and said first conduit means into the manifold and additional fluid mixture will flow through said second conduit means in response to movements of said choke valve.
