摘要： 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.

摘要： An exhaust gas flow concentration system for a catalyst includes an inlet that receives a flow of exhaust gas from an exhaust pipe of an exhaust system, a stationary tube in communication with the inlet and disposed upstream from the catalyst, and an extension tube in communication with the stationary tube and disposed upstream from the catalyst, where the extension tube includes a cross-sectional area less than a cross-sectional area of the catalyst. A displacement device is coupled to the extension tube and is configured to (i) displace the extension tube relative to the stationary tube downstream towards the catalyst as a temperature in the exhaust system decreases away from a light-off temperature of the catalyst and (ii) retract the extension tube relative to the stationary tube upstream away from the catalyst when the temperature in the exhaust system reaches the light-off temperature of the catalyst.
