| 摘要 |
<p>The invention relates to an internal combustion engine, and a method in an internal combustion engine comprising at least one cylinder (5a) with a piston (5b), at least one intake valve (5) at each cylinder, a variable valve lift profile system (4) adapted to actuate the intake valve (5) selectively in either of at least two valve lift profile modes (LL, HL), and a variable valve timing system (8) adapted to adjust the timing of the intake valve (5) actuation. The method comprises the step of controlling the variable valve timing system (8) so that, at a mode change from a first valve lift profile mode (LL) to a second valve lift profile mode (HL) wherein the maximum lift of the intake valve (5) is greater than in the first valve lift profile mode (LL), the amount of air captured (AR1c, AR2c) in the cylinder (5a) during an engine cycle is reduced as a result of the mode change.</p> |
