摘要： The system has a high-pressure pump having a number of mechanical pumping elements for pumping high-pressure fuel to a common rail; and a number of injectors communicating with the rail and activated to inject a quantity of fuel sequentially into the corresponding cylinders of the engine. Each pumping element has a delivery at least equal to the maximum draw of each injector, and is activated in phase with at least one of the injectors to minimize the variations in fuel pressure in the rail. Each pumping element may be activated by a cam, which may even have a segmented profile to effect a portion of the travel of the respective pumping element in phase with a corresponding injector.

摘要： An injection method applicable to engines featuring a Denox catalyst for reducing the nitric oxide content of exhaust gas. In addition to the main injection phase, the method presents a post-injection phase predominantly performed during the exhaust stroke of the engine, so that the diesel fuel injected does not contribute--or only to a very limited extent--towards combusion, but is supplied directly to the Denox catalyst to increase its efficiency. The method involves no alterations to the injection system, by virtue of post-injection being controlled and optimized by the central unit controlling injection as a whole.

摘要： An automatic regeneration initiating method presenting, in addition to the main injection phase, an auxiliary post-injection phase, for injecting a given quantity of fuel directly into the cylinders during the expansion stroke when the temperature in the combustion chamber is still high enough for its combustion, so as to increase the temperature of the exhaust gas and initiate combustion of the filtered particulate. By appropriately regulating the amount of fuel injected and the timing of the post-injection phase, incomplete combustion products are formed for assisting combustion of the dry particulate and lowering its ignition temperature.
