Abstract
The effect of fuel injection on the flow and the spray/swirl and spray/piston interactions in direct-injection diesel engines have been investigated by simulating diesel sprays with gaseous jet(s) injected through centrally located, single- and multi-hole nozzles into the quiescent and swirling air of a motored engine running at 200rpm and incorporating a flat piston and a re-entrant piston-bowl. The axisymmetric velocity field with and without ‘fuel’ injection was characterised by laser velocimetry near TDC of compression in terms of spatially-resolved ensemble-averaged axial and swirl velocities, the ‘fuel’ concentration field was quantified by laser Rayleigh scattering and the two-dimensional flow was visualised by gated still photography using hollow microballoons as light scatterers.
