Authors Abstract
Content
The trend of higher specific power and increased volumetric efficiency leads to unwanted combustion phenomenon such as knocking, pre-ignition and self-ignition.
For four-stroke engines, the literature reports that knocking depends, to a large extent, on the ignition angle, the degree of enrichment and the volumetric efficiency. In recent research, knock investigations in two-stroke engines have only been carried out to a limited extent.
This paper discusses an investigation of the influence of various parameters on the knock characteristics of a small, high-speed, two-stroke SI engine. In particular, the degree of enrichment, the volumetric efficiency and the ignition timing serve as the parameters.
