Effects of Electric Fields on the Combustion Characteristics of Lean Burn Methane-Air Mixtures

Fang, Jianfeng; Wu, Xiaomin; Duan, Hao; Li, Chao; Gao, … - In: Energies 8 (2015) 4, pp. 2587-2605

In this work, the effects of the electric fields on the flame propagation and combustion characteristics of lean … is remarkably stretched by the applied electric field, the stretched flame propagation velocity and the average flame … propagation velocity are all accelerated significantly as the input voltage increases. This indicates that the applied electric …

Combustion characteristics and optimization of CPG (compressed producer gas) in a constant volume combustion chamber

Soid, S.N.; Zainal, Z.A. - In: Energy 73 (2014) C, pp. 59-69

PG (producer gas) from biomass gasification can be used either in SI (spark ignited) or CI (compressed ignited) engine. Present study evaluates fundamental combustion characteristics of SI CPG (compressed producer gas) in a CVCC (constant volume combustion chamber) at various equivalence ratios...

The effects of spark timing, unburned gas temperature, and negative valve overlap on the rates of stoichiometric spark assisted compression ignition combustion

Olesky, Laura Manofsky; Martz, Jason B.; Lavoie, George A. - In: Applied Energy 105 (2013) C, pp. 407-417

Spark assisted compression ignition (SACI) combustion is a potential means of extending the high load limit of homogeneous charge compression ignition (HCCI) while maintaining high thermal efficiency. In these experiments, an HCCI engine equipped with fully-flexible valve actuation was used to...
