Internal combustion engine i.e. petrol engine, operating method, involves compressing ignitable gas mixture in chamber in compression stroke, and changing remaining gas amount and/or injecting time for working cycle to intermediate value

摘要

The method involves compressing an ignitable gas mixture in a combustion chamber (2) of an internal combustion engine (1) in a compression stroke, where the mixture has the remaining gas. The gas mixture is self-ignited during the compression stroke. The remaining gas amount and/or the injecting time for a working cycle is changed to an intermediate value, which deviates from a value associated to a target load, during load change of an output load to the target load. Independent claims are also included for the following: (1) a controller comprising a unit for operating an internal combustion engine (2) a computer program for executing a method for operating an internal combustion engine.
