Description
<p>In the super lean burn, the combustion limit (lean limit) is expanded by engine technology with an increased tumble ratio. In order to further expand the lean limit, it is important to combine fuel technology and engine technology. In this study, using two types of engines with different tumble ratios, the influence of fuel composition on the lean limit (the excess air ratio at the IMEP fluctuation rate of 3 %) was investigated. As a result, it was confirmed that it is possible to further expand the lean limit by changing the fuel composition. The lean limit expansion effect by changing fuel composition is almost independent of the two types of engines. It was also confirmed that the laminar burning velocity of the fuel and the lean limit show a good correlation.</p>
