Besides the benefits when used as the single fuel, ethanol can also leverage the ...
An experimental study was made to investigate the effect of swirl ratio, spark plug electrode direction and spark plug position on in-cylinder combustion in a spark-ignited natural gas engine. Flame propagation in a single-cylinder visualization engine was observed from bottom of...
spark plug location, spark plug electrode(s) orientation and spark gap; and operational sources—engine speed, load and ignition system performance [1,2,3,4,12,13]. Many of the experimental works quantify CCV by computing the coefficient of variation (CoV) in one or more easily measured met...
