Abstract
Methods and systems are provided for injecting and combusting an amount of gaseous fuel during an exhaust stroke of a cylinder combustion event in order to reduce turbo lag and reduce a duration of time required for an exhaust catalyst to light-off during transient events. In one example, when an increase in torque demand is greater than a threshold, a first amount of gaseous fuel may be combusted during a compression stroke of a cylinder combustion event and a second amount of gaseous fuel may be combusted during an exhaust stroke of the combustion event. The second amount may be adjusted based on the increase in torque demand.
