Method to control the combustion of a compression ignition engine (1) with reactivity control through the injection temperature; the control method provides for the steps of: establishing a quantity (Q) of fuel to be injected into a cylinder (2); injecting a first fraction (F1) of the quantity (Q) of fuel fed by a first feed system without active heating devices, preferably equal to at least 70% of the quantity (Q) of fuel, at least partially during the intake and/or compression stroke; injecting a second fraction (F2) of the quantity (Q) of fuel fed by a second feed system provided with at least one active heating device (12; 13), and equal to the remaining fraction of the quantity (Q) of fuel, into the cylinder (2) at the end of the compression stroke and preferably at no more than 60° from the top dead centre (PMS); and heating the second fraction (F2) of the quantity (Q) of fuel to an injection temperature (T) of over 100°C, before injecting the second fraction (F2) of the quantity (Q) of fuel. |
