摘要： 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.

摘要： A method for an engine, comprising: during a first condition comprising a high engine temperature, injecting a first quantity of liquid petroleum gas into a first engine cylinder at a first timing during an intake stroke; and injecting a second quantity of liquid petroleum gas into the first engine cylinder at a second timing during a compression stroke following the intake stroke. In this way, combustion knock and cylinder pre-ignition may be mitigated without retarding spark ignition and/or limiting engine load, thereby allowing for maximum engine performance.

摘要： Methods and systems are provided for adjusting a phase of gaseous fuel delivered to fuel injectors of a fuel delivery system. In one example, a method may include adjusting a fuel pressure in a fuel delivery system to deliver fuel in each of a liquid and a gaseous phase during different engine operating conditions. The fuel pressure may be based on a temperature, composition, and desired phase of the fuel.

摘要： 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.
