See full text

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.
