Abstract
A Venturi-based purge vapor supply system for a turbulent jet ignition (TJI) engine and its method of operation utilize an air compressor configured to output pressurized air, a vapor canister configured to store purge vapor evaporated from liquid fuel housed in a fuel tank, a purge vapor injector configured to inject a mixture of air and purge vapor into a pre-chamber of the TJI engine and an ejector tee connected between the air compressor, the vapor canister, and the purge vapor injector, the ejector tee having a Venturi-based design such that the pressurized air from the air compressor draws the purge vapor into the ejector tee and combines the air and the purge vapor to form and output the mixture of air and purge vapor to the purge vapor injector.
