“…In this case, the value of this parameter was 4 kHz. Based on the test results and literature, a significant, but not a hard level of knocking [4], [5] was chosen for the maximum pressure deviation KP_PK (Knock Peak) equal to 3.0-4.0 bar [13]- [15]. This value was obtained as a result of engine tests and compared with a distinctly audible noise of knocking combustion.…”

The work describes the properties of natural gas as a engine fuel, as well as a method for evaluating knocking combustion at a test bench, a 3D numerical model of the combustion process of spark ignited (SI) gas engine and methods for assessing the probability of knocking combustion based on this model. The probability of knocking combustion, which characterizes the boundary condition between normal combustion and knocking, is determined (8%). An optimization study of the influence of adjustment parameters on the probability of knocking based on a three-dimensional numerical model is carried out. The developed and tested technique allows one to monitor the tendency of the influence of various adjustment parameters on the probability of knocking in a SI gas engine

 Abstract: The paper describes a method for evaluating knocking onset with computational fluid dynamics (CFD) numerical model of the combustion process of spark ignited (SI) gas engine and methods for assessing the probability of knocking combustion based on this model. The probability of knocking combustion, which characterizes the boundary condition between normal combustion and knocking, is determined (8%). An optimization study of the influence of adjustment parameters on the probability of knocking based on a three-dimensional numerical model is carried out. The developed and tested technique allows one to monitor the tendency of the influence of various adjustment parameters on the probability of knocking in a SI gas engine. Keywords: natural gas, spark ignition gas engine, knock onset, computational fluid dynamic, combustion process, start of combustion test bench, knocking probability, knock index.

“…1. Detonation theory: This theory postulates that the spark ignited flame front accelerates to supersonic velocities in the end-gas region and hence produces shock waves [6], 2. Flame acceleration theory: This theory postulates that knock results from rapid burning of the reactants by the spark ignited flame [7,8,9], 3.…”

The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.
