Methane slip from large-bore, two-stroke, natural gas engines contribute significantly to green-house gas emissions. Optimizing the design and functionality of pre-combustion chambers is one potential solution to reducing these emissions. The objective of the study was to optimize a pre-combustion chamber to improve combustion efficiency and reduce methane emissions from a Cooper Bessemer GMV-4TF. Computational fluid dynamic simulations were used to investigate the effects of varying pre-combustion chamber design parameters, including nozzle angle, flow area, and volume. The most effective design...
Methane slip from large-bore, two-stroke, natural gas engines contribute significantly to green-house gas emissions. Optimizing the design and functionality of pre-combustion chambers is one potential solution to reducing these emissions. The objective of the study was to optimize a pre-combustion chamber to improve combustion efficiency and reduce methane emissions from a Cooper Bessemer GMV-4TF. Computational fluid dynamic simulations were used to investigate the effects of varying pre-combustion chamber design parameters, including nozzle angle, flow area, and volume. The most effective design was manufactured and evaluated experimentally on a GMV-4TF.
