NGML researchers continue to focus their efforts on the ability to fully understand and measure scavenging, while work continues to develop modified engine port geometries and other low-cost components to control scavenging in two-stroke cycle engines.
Literature reveals that the currently-available discharge coefficients are derived from ports that are a fraction of the size of the ports used in large-bore two-stroke cycle engines.
When due to high intake air temperature, it causes the peak firing pressure to occur at a later time in the
two-stroke cycle. Since cylinder scavenging is highly dependent on the proper timing of cylinder pressurization and blow down, the later occurring flame tends to leave high pressure exhaust gases in the cylinder when the intake ports open.
