Abstract

Secondary Fuel Injection (SFI) is applied to regenerate Diesel Particulate Filter (DPF) which is an after-treatment device of diesel engine. Under this system, ensuring complete evaporation and an optimum mixture distribution in the exhaust line is important. This report focuses on impingement spray in high temperature field to understand its physical phenomena using scattered light photography method and Exciplex fluorescence method with swirl nozzle and n-dodecane. As a result, in evaporation field, the specific vortex of swirl spray disappears after wall impingement in Pinj=1 MPa, but the vortex is maintained in Pinj=4 MPa. And vapor concentration distribution in Pinj=4 MPa is more widely distributed than 1 MPa.
