Summary on Grant Application Form |
|
The work would be divided between Kings College and UCL, and would be part of a collaborative programme with Jaguar and Ford who would supply equipment, engine hardware guidance and financial support. Experimental work would apply LDA and flow visualisation techniques to an optical engine both to provide information to parallel CFD studies and also to gain un understanding of the effects of port design on di gasoline engine airflows. Meanwhile spray visulisation and laser diffraction techniques would be applied on a test rig to differnet di fuel system designs to generate flow data to support spray modelling. This would be followed by investgations using a firing optical engine to record the behaviour of both liquid fuels (using a high speed camera arrangement) and fuel vapour (through the application of LIF). The theoretical part of the project would apply STAR-CD CFD coding to the do engine design in order to compare results with the LDA and flow visualisation work. Spray breakup and evaporation models would be developed and incorporated into the coding. Predictions would be made of fuel vapour distributions for comparison with LIF measurements from the optical engine.The last part of the programme would comprise emissions investigations on a single cylinder di enginer using statistical techniques to evaluate the effects of variable valve events.
