Abstract
Methods and systems are presented for improving operation of an engine that includes an evaporative emissions system. In one example, the methods and systems adjust an amount of fuel that is delivered to a pre-chamber of an igniter in response to purging fuel vapors and/or an indication of hydrocarbon breakthrough of a carbon filled fuel vapor storage canister.

A method for operating a vehicle, comprising:
- via a controller, increasing an amount of fuel that is supplied via an igniter in response to purging fuel vapors from a carbon filled canister, and where the igniter includes a pre-chamber.
A vehicle system, comprising:
- an engine including an igniter that includes a pre-chamber;
- a fuel tank;
- a carbon filled fuel vapor storage canister in selective fluidic communication with the fuel tank;
- a canister purge valve;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to increase an amount of fuel supplied via the igniter in response to purging fuel vapors from the carbon filled fuel vapor storage canister.
