Improving fuel economy and reducing emissions in gasoline engines require fine fuel atomization. This report discusses atomization characteristics of a newly developed air-assisted atomization method in which air is blown radially from an outside circumference onto the liquid film of the fuel sprayed from the upstream-swirl-type injector. This method achieves fine fuel atomization even if the air passage area is increased and air flow velocity is decreased. Moreover, air flow under the mixture spray nozzle suppresses fuel particle diffusion.
