Includes bibliographical references (p. 103-109). The CFR engine is the standardised research engine used for the measurement of knock resistance of fuels through the Research Octane Number (RON) and Motor Octane Number(MON) tests. In standard production engines, knock manifests as an almost instantaneous pressure rise followed by knock ringing" pressure oscillations of similar magnitude. However, knock in the CFR engine is characterised, and measured by, a steep, but more gradual pressure rise, followed by ringing of much lesser magnitude. It has been previously proposed that a cascading autoignition", resulting from an in-cylinder temperature gradient, is responsible for this unique pressure development. 2015-01-05T06:50:08Z 2015-01-05T06:50:08Z 2011 Master Thesis Masters MSc http://hdl.handle.net/11427/11357 eng application/pdf Department of Mechanical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
