Diesel oil post injection process for diesel engine, involves increasing temperature of exhaust gas to accelerate speed of oxidation of carbon particles for regenerating filtration device of exhaust gas products

摘要

The process involves injecting diesel oil, up stream of an oxidation catalyst, from an electro-magnetic injector (9) for pulverizing the oil by compressed air. The temperature of an exhaust gas is increased to accelerate the speed of oxidation of the carbon particles for regenerating a filtration device of exhaust gas products. The temperature is increased when the start of binding of the particles is detected. An Independent claim is also included for a device for post injection of diesel oil.
