This work describes an injector spray/wall interactions simulation (SWIS) that has been developed, which aides in optimizing the injector location design and injector type and spray pattern for best engine driveability and performance. It provides information on the intake manifold puddle fuel for engine temperature ranging from -40 to 250{sup 0}F. SWIS is based on a first principles wall wetting and fuel vaporization model which includes the liquid fuel film flow that is established following the impaction of the injected fuel spray on the walls of the intake manifold port and valve. The intake manifold port and valve geometry, injector location relative to the cylinder head configuration, injector type and radial fuel spray distribution are among the several design parameters which can be evaluated using SWIS.
