Abstract
Methods and systems are provided for adjusting ignition energy of the spark required for combustion of gaseous fuel injected during an exhaust stroke of a cylinder combustion event to reduce turbo lag. In one example, a method includes combusting a first amount of gaseous fuel during a compression stroke of a cylinder combustion event using a first ignition energy and combusting a second amount of gaseous fuel during an exhaust stroke of the cylinder combustion event using a second ignition energy, the second ignition energy lower than the first ignition energy. The second ignition energy may be adjusted based on in-cylinder pressure and cylinder load.
