Abstract

The invention concerns a secondary fuelling system for fitting to an internal combustion engine, the internal combustion engine being configured to be fuelled with a primary fuel and the secondary fuelling system being configured to supply a controlled quantity of a secondary fuel, in addition to the primary fuel, to a combustion chamber of the engine. The secondary fuelling system is configured to determine an engine parameter indicative of quantity of primary fuel supplied to the combustion chamber, to calculate a required quantity of secondary fuel to be supplied to the combustion chamber as a function of the monitored engine parameter, and to supply the required quantity of secondary fuel to the engine In certain embodiments the secondary fuelling system carries out the determination of the engine parameter and the calculation of the required quantity of secondary fuel during each engine cycle and in that the required quantity of secondary fuel determined in one engine cycle is supplied to the combustion chamber in the same engine cycle or in the following engine cycle.
