I read your magazine on a regular basis, and I've noticed thatrnsome of your road tests describe new or redesigned engines that have fuel-injection nozzles with more orifices than the nozzles on previous models. I'm no fuel-injection wizard and only have a rudimentary knowledge of how these systems work, so I don't understand the benefit of putting more holes in the same nozzle. In carburetors, richening the fuel mixture is accomplished by installing a jet with a larger orifice. If engine designers want to get more fuel into the combustion chambers with a fuel-injection system, why don't they just enlarge the existing hole in the nozzles rather than adding holes?
