一种内燃机以及内燃机操作的方法
摘要：
一种内燃机及其操作的方法，涉及从进气歧管(18)到气缸(11)的燃烧室的进气口提供进气；选择性的采用第一操作曲线(30)操作进气门和，按需求，切换进气门的选择性操作到第二操作曲线(31)，其中第二操作曲线的进气门的关闭相对采用第一操作曲线的进气门的关闭延迟；其中从第一操作曲线到第二操作曲线的切换点(43)或者之前，进气歧管内的进气压力被增加。
摘要（英）：

An internal combustion engine and a method of operation are described involving: supplying intake gas from an intake manifold (18) to an air intake port of a combustion chamber in a cylinder (11); selectively operating an air intake valve using a first operating profile (30) and, on demand, switching selective operation of the air intake valve to a second operating profile (31) in which the closing of the air intake valve is delayed compared to the closing of the air intake valve using the first operating profile; wherein at the point (43) of or prior to switching from the first operating profile to the second operating profile the pressure of the intake gas in the intake manifold is increased.
