Analysis of Combustion Process in Dual Fuel Diesel Engines: Knock Phenomenon Approach 2005-01-1132

In order to study the combustion process in a dual fuel direct injection compression ignition engine, a two-zone model has been developed. Two distinct zones of interest are gaseous fuel-air mixture zone and liquid pilot fuel zone. The present model uses methane as the main gaseous fuel.
One of the problems which mostly occur in both part load and full load operating conditions of dual fuel engines is the onset of knock. The main target of this paper is the investigation of knock formation resources and effective parameters such as air-fuel equivalence ratio, initial temperature and injection timing. The numerical results have been compared with the experimental data of OM-355 direct injection dual fuel diesel engine and the work of other researchers.
