Abstract

The invention relates to a waste gas limiter for a combustion engine. The combustion engine incorporates a charge pressure sensor whereby the waste gas limiter is arranged to limit the amount of power medium injected into the engine to a maximum amountof power medium per working cycle which depends on a charge pressure measured by the charge pressure sensor. The waste gas limiter itself incorporates an anticonstriction device designed to signal to the waste gas limiter that substitute charge pressure applies which is greater than the measured charge pressure when the difference between a required amount of power medium per working cycle and an injected amount of power medium per working cycle has during a certain time been greater than a certain amount while the charge pressure measured by the charge pressure sensor has at the same time been below a certain reference pressure. The invention further relates to a method for anticonstriction control, a computer program intended to execute steps to anticonstriction control, and a storage medium on which such a computer program is recorded.
