Computational Investigation on the Effects of Pre-Chamber Volume in an Active Narrow-Throat Pre-Chamber Engine

ASME 2023 ICE Forward Conference, 2023
Abstract To understand key physical aspects of volume in narrow-throat pre-chambers, computational fluid dynamics simulations were performed using CONVERGE™. A major advantage of a narrow-throat feature is to allow for drop-in replacement of a diesel injector, hence facilitating technology deployment.

Effects of pre-chamber specifications on lean burn operation in a pre-chamber engine with fuel reformed gas

SAE Technical Paper Series, 2023
<div class="section abstract"><div class="htmlview paragraph">Lean combustion has been well known to be an effective method to improve the thermal efficiency. However, leaner mixture is prone to cause the unstable combustion and poorer unburned hydrocarbon (UTHC) emissions. Pre-chamber turbulent jet combustion has been proved to enhance the
