Results are presented from flow-rig tests in which water from an automotive engine injector was sprayed on to a small heated surface in the presence of both steady and pulsative air flow. The injection was intermittent and synchronized with the pulsating air flow. The aim of the tests was to improve understanding of some of the basic heat and mass transfer mechanisms that occur in port-injected sparkignition engines where fuel is usually sprayed on to the back of the inlet valve. The main observations focused on the heat transfer to the film and the entrainment of the spray and film by the air stream.
