Abstract

Methods and systems are provided for adjusting a compression ratio of a combustion chamber. In one example, a method may include altering an axial position and rotational orientation of a control element comprising a spark plug and a fuel injector in response to an engine operation. The method further includes changing a distance between intake and exhaust valves of a cylinder to the control element, the spark plug, and the fuel injector.
