Venturi-based purge vapor supply system for turbulent jet ignition engines

A method of operating a Venturi-based purge vapor supply system of a turbulent jet ignition (TJI) engine, the method comprising:

• obtaining, by a controller, one or more engine operating parameters;
• and
• based on the one or more engine operating parameters, controlling, by the controller, at least one of an air compressor, a purge pump, and first and second valves, the first valve being connected to the air compressor and the second valve being connected to the purge pump,
• wherein the system comprises a vapor canister connected to the purge pump, and a purge vapor injector configured to directly inject a mixture of air and purge vapor into a pre-chamber of the TJI engine, and
• wherein the system further comprises an ejector tee connected between the first and second valves and the purge vapor injector, the ejector tee having a Venturi-based design such that pressurized air from the air compressor draws purge vapor into the ejector tee and combines the pressurized air and the purge vapor to form and output the mixture of air and purge vapor to the purge vapor injector.
