Method for reactivating a cylinder of a multicylinder internal combustion engine
First Claim
1. A method for reactivating at least one cylinder of a multicylinder internal combustion engine having electromechanically actuated charge cycle valves after interruption of the actuation of at least one charge cycle valve in which the actuation of the charge cycle valve is resumed, comprising operating the cylinder for at least one cycle with full load control times and without fuel being supplied and without ignition, and wherein the cylinder is operated temporarily with different control parameters than the other cylinders and further wherein the load of the cylinder is kept below a predefined load threshold, and the other cylinders are operated with a higher load.

Abstract
An internal combustion engine has a plurality of cylinders to which electromechanically actuated charge cycle valves are assigned. After interruption of the actuation of at least one charge cycle valve of one cylinder the latter is first operated with reduced load and adapted control parameters after the charge cycle valve actuation is resumed. In this way, reliable functioning of the electromechanically actuated charge cycle valves is ensured after interruption of the actuation of at least one charge cycle valve.

2. A method for reactivating at least one cylinder of a multicylinder internal combustion engine having electromechanically actuated charge cycle valves after interruption of the combustion for a plurality of working cycles in at least one cylinder in which the combustion in the cylinder is resumed, comprising operating the cylinder for at least one cycle with full load control times and without fuel being supplied and without ignition, and wherein the cylinder is operated temporarily with different control parameters than the other cylinders and further wherein the load of the cylinder is kept below a predefined load threshold, and the other cylinders are operated with a higher load.
