Analysis of the Combustion of Methane in a Spark Ignition Internal Combustion Engine
Published January 30, 1991 by Institution of Mechanical Engineers in United Kingdom
This paper describes an investigation to establish the flame front speed and mass fraction burned when methane is used as a fuel for internal combustion engines. An experimental test rig was designed and built, incorporating a Rover "A" series four cylinder overhead valve spark ignition engine. A pressure transducer installed in the cylinder head was to provide data for use in a thermodynamic computer program to calculate the mass fraction burned. The results are compared with data for petrol combustion and show that the combustion duration for methane is longer and the flame front speed is approximately half of that of petrol.
