ABSTRACT:
A fuel supply system for an internal combustion engine having an intake manifold, an exhaust manifold, a carburetor and an air cleaner mounted on the carburetor. The system includes a heat exchanger in the exhaust manifold and a converter within the heat exchanger. An adapter plate is mounted on the intake manifold and the carburetor is mounted on the adapter plate. The adapter plate has passages providing communication between the carburetor and the intake manifold and with a metering valve mounted on the adapter plate. A main liquid fuel inlet line having a pressure regulator, a solenoid valve, a vacuum responsive pressure regulator and a vacuum controlled needle valve is connected to a fuel pump. The fuel inlet line is split into a primary fuel line and a secondary fuel line which are connected to the converter. A solenoid valve and a check valve are located in the secondary line and a check valve is located in the primary line. A water supply line having a pressure regulator, a solenoid valve, a fixed orifice restrictor and a check valve is connected to the converter. A vacuum controlled switch is connected to the intake manifold and is electrically connected to the solenoid valves in the secondary fuel line and the water supply line to open the solenoid valves when the vacuum in the intake manifold increases as the engine accelerates. A fuel vapor line connects the converter and the metering valve to supply fuel vapor and steam to the metering valve to mix with air flowing through the carburetor to provide a hot fuel vapor, steam and air mixture to the intake manifold. The vacuum controlled switch is connected to the vacuum responsive pressure regulator and the vacuum controlled needle valve to provide increased fuel flow through the main fuel inlet line as the engine accelerates and the vacuum in the intake manifold increases.
