Abstract
Methods and systems are provided for adjusting canister purge flow based on robustness conditions of pre-chamber ignition of an engine at non-steady state operating conditions wherein robustness conditions comprise operating conditions wherein the engine operates at air to fuel ratios that are under or exceed stoichiometric ratios and canister purge flow is adjusted proportionally based on a degree of robustness of the robustness conditions. Further methods are provided for adjusting canister purge flow based on robustness conditions of pre-chamber ignition of the engine at steady state operating conditions.
