RISNumerical Investigation of Methane Number Effect on Combustion, Performance, and Emissions in a Heavy-Duty Spark Ignition Natural Gas Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In this study, the effects of methane number (MN) on the numerical conversion of a heavy-duty diesel engine to a spark ignition (SI) natural gas engine were investigated. A high-compression-ratio configuration ...
A Numerical Investigation Into the Effects of Equivalence Ratio and Exhaust Gas Recirculation on Performance and Operating Range in High Compression HCCI Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study investigates the performance of a high compression ratio engine converted to homogeneous charge compression ignition (HCCI) operation. A total of 24 case studies were conducted with φ = 0.22–0.29 and ...
