Abstract
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.
