Analysis of the injection process in direct injected natural gas engines
Abstract
The analysis was based upon a series of three-dimensional computational fluid dynamics (CFD) calculations of natural gas (NG) injection in engine combustion chambers and constant volume chambers. Simulations of injection into constant volume chambers were used to investigate the fundamental behavior of NG jets. Calculations of engine injection, which include a moving piston, were used to study the effects of combustion system design.
