Abstract:
1. A method for determining an optimum positioning zone of an ignition plug in a combustion chamber, where the ignition plug is fitted with a semiconductor element which has a flat face on which fuel is deposited in an ignition operation, wherein the method comprises the steps of: determining an optimum fuel flow rate value using a test ignition plug located outside the combustion chamber, the test ignition plug being identical to the ignition plug, successively measuring successive test ignition test, where for each measurement, a test tool having a same size as the ignition plug is positioned in a different location of the combustion chamber, and for each measurement and each position, a quantity of fuel collected at a surface of one end of the test tool is measured; determining the fuel flow rate values corresponding to the measured quantities of fuel; comparing the fuel flow rate values corresponding to the measured quantities of fuel and of the optimum fuel flow rate value; and determining the optimum positioning zone following the comparison.
