Web20 aug. 2024 · 5.1 The methane number (MN) is a measure of the resistance of the gaseous fuel to autoignition (knock) when used in an internal combustion engine. The relative merits of gaseous fuels from different sources and having different compositions can be compared readily on the basis of their methane numbers. WebNote: 1 Joule = 2.3901 × 10 −4 kcal. Usage. The Wobbe index is expressed in MJ/Nm³ (where the ill-advised symbol 'Nm³' is intended to mean 'm³ in Normal conditions, much against the BIPM prescription for writing SI units), or sometimes in BTU/scf.. There are three ranges or "families" of fuel gases that have been internationally agreed based on Wobbe …

WebThe Methane Number of the gas is of extreme importance for optimized engine operation. The knock resistance of the fuel must be known to set the operating space of the engine and the Methane Number available defines the engine setup to a high degree.
WebHigh methane numbers mean high knock resistance; high knock resistance, in turn, means high efficiencies and thus lower CO 2 emissions. If methane numbers are too low, knock may cause engine damage or lead to losses in efficiency and performance if engine operation has to be adjusted to avoid knocking combustion.
