Research on Combustion Noise for Controlled Auto Ignition Engine Fueled with Natural Gas Effect of Stroke Bore Ratio and Ignition Timing 2016-32-0044

One of the issues involved in compression ignition combustion is the increase in combustion noise from engine mechanical systems caused by rapid combustion. When the fuel used is natural gas, with its high ignition temperature, the compression is increased relative to gasoline, so that combustion becomes even more rapid. The present research pursues the issue of noise by clarifying the distinctive features of combustion noise through tests focused on the two topics of stroke-bore ratio (S/B ratio) and ignition timing for engine structures deformation mode. From these results, we verified combustion noise trend and occurrence factor.
