The effects of two commonly used methods for altering the combustion process in a spark-ignition engine are examined using pressure measurements and high-speed schlieren photography. A square cross-section visualization engine with two quartz sidewalls was used to allow optical access over the entire four-stroke operating cycle. Engine operation with a shrouded intake valve, which changed the intake-generated flow, and with a stepped piston, which changed the compression-generated flow, are compared to a base condition. In addition, cyclic variations in burning are examined for all cases.
