An Examination of the Combustion Processes of a Methane Fuelled Engine When Employing Plasma Jet Ignition 891639
Examination is made of the changes that take place in the major parameters of the combustion process and engine performance when using three different designs of plasma jet igniters of the open cavity type in a methane fuelled single cylinder engine. The characteristics of the combustion process were analysed employing a two-zone diagnostic model based on cylinder pressure-time development data.
The use of plasma jet igniters with methane as a fuel enhanced the rates of burning in the initial stages of combustion, especially with very lean mixtures. The lean limit of engine operation was also extended. Their use for near stoichiometric fast burning mixtures tends in comparison to contribute little towards enhancing engine performance.
