Abstract
A method for operating an internal combustion engine in a state of controlled self-ignition. The internal combustion engine includes a combustion chamber, at least one intake valve and at least one exhaust valve whose opening times can be changed. A fresh mixture is introduced into the combustion chamber during an intake stroke and an ignitable gas mixture is produced in the combustion chamber by way of the introduction of fuel and compressed in a compression stroke, whereby the gas mixture self-ignites toward the end of the compression stroke.The fresh mixture is introduced into the combustion chamber by way of a compression mechanism during the intake stroke.
