Study carried out to determine influence of port and piston shape on dynamics of air induced by 4-stroke engine for commercial and passenger vehicles; engine design is arranged to produce 2 separate effects which combine to form required air motion; these are induction swirl, created during induction by suitable port design, and "squish" resulting from shape of piston crown and occurring toward end of compression stroke; results of tests on rig were used to estimate performance of various ports; squish process was investigated by calculation, and effects of variations in piston crown design considered.
