<p>An injection method presenting, in addition to the main injection phase, an auxiliary pre-injection phase during the induction stroke of the engine. The pre-injection phase is preferably performed at the start of the induction stroke, and provides for injecting a small quantity of fuel equal to a few percent of the fuel quantity injected during the main injection phase, so that, during the compression stroke, partially oxidized and/or peroxidized products with a strong chemical affinity are formed, and which act as combustion accelerators for minimizing fuel ignition lag of the main injection phase and so reducing the nitric oxides and noise produced during combustion.</p> |
