METHOD OF OPERATING A DIESEL ENGINE WITH A VIEW TO MAKING IT EASIER TO REGENERATE A PARTICLE FILTER IN THE EXHAUST SYSTEM

摘要

Diesel or lean-burn engines which are fitted with an exhaust system provided with a particle filter are supplied with a fuel containing an additive capable of lowering the temperature at which the soot particles trapped by the particle filter can be burned and which essentially consists of an iron compound or essentially consists of an iron compound and of a cerium compound, and wherein the particle filter through which the exhaust gases produced by the combustion of the fuel in the engine pass is a catalytic filter in which the catalyst assists with the combustion of the soot particles; this improves soot combustion dynamics, particularly at low temperatures.
