可視化装置を用いた副室式ガスエンジンの現象把握

抄録

In order to understand what occurs in a pre-chamber gas engine, we focused on the combustion process and attempted visualization of combustion from inside and outside of the pre-chamber. The vibration of pressure in the pre-chamber is synchronized with that of light intensity, and vibration is a phenomenon that occurs in the pre-chamber. It was confirmed that when the nozzle diameter was reduced, combustion in the main chamber was delayed due to relighting after jet light disappeared. It was confirmed that the vibration and light cycle at the combustion of the pre-chamber were synchronized from the bottom view.
