种操作使用气体燃料的内燃机的方法包括将燃料通过中央点喷射和多点喷射提供至多个气缸。提供了充分空气/燃料混合的中央点喷射可提供大部分稳态燃料供给，且多点喷射用于在稳态过程中补充中央点喷射并用于提供对负载变化的快速瞬时响应。 A method of operating an internal combustion engine with gaseous fuel includes providing fuel to a plurality of cylinders with both central point injection and multipoint injection. Central point injection, which provides good air/fuel mixing, may provide a majority of steady-state fueling, and multipoint injection is used for supplementing the central point injection during steady-state and for providing rapid transient response to load changes.
