1. A method for controlling an internal combustion engine having an air-intake channel and an output channel and being equipped with at least one of an air-intake switchover to change the resonance geometry of the air-intake channel and means for changing the resonance geometry of the output channel, the method comprising the steps of:
- increasing the power of the engine in predetermined operating states of said engine by changing the geometry of at least one of said channels; and
,in the case of drive slip control, causing at least one of said air-intake switchover and said means to be adjusted to low power resonance.

Abstract
The invention is directed to a method and an arrangement for controlling an internal combustion engine wherein a torque reducing control of the opening times of the inlet and outlet valves of the engine and/or a torque reducing control of the geometry of the inlet or outlet systems of the engine is undertaken in the case of a drive slip control.

2. A method of controlling an internal combustion engine having inlet and outlet valves and an air-intake channel and an output channel and being equipped with the following:
- first means for controlling said inlet and outlet valves;
second means for changing the geometry of said intake channel; and
, third means for changing the geometry of said output channel;
the method comprising the steps of;controlling one of said first, second and third means to reduce the power of said engine when a reduction in torque is required; providing a desired value (Mdes) for said torque; forming an actual value (Mact) for said torque; forming the difference (Δ
) between said desired value (Mdes) and said actual value (Mact); and
,determining and outputting at least one of the following quantities in dependence upon said difference (Δ
);a correction to shift the ignition angle; and
,a number of individual ones of the cylinders of said engine to which the metering of fuel is interrupted. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10)
