Title:
SYSTEM FOR DISPENSING FUEL INTO AN EXHAUST SYSTEM OF A DIESEL ENGINE
Document Type and Number:
WIPO Patent Application WO2006055558
Kind Code:
A3
Abstract:
A system (201) is disclosed for dispensing fuel into the transient flow of an exhaust system to control exhaust emissions. A controller (42) initiates the delivery of fuel into the exhaust when an emissions control device, such as a diesel particulate filter (36), requires increased exhaust temperatures for regeneration. In operation, pressurized fuel and pressurized air are supplied to a fuel delivery device (40), wherein a fuel injector (84) pre-mixes fuel with air. The fuel-air mixture is then dispensed into the exhaust flow through a nozzle (92), causing a rapid pressure drop in the mixture that results in the pressurized air expanding rapidly, breaking the fuel spray into fine particles.
