Hello.
Here is 2-stroke, we call it PatTwo, running on Miller cycle:
With a separator the space between the two ends of the piston is divided into two sections; the separator comprises a passage between the two sections and a valve that controls the passage from fully closed to wide open.
The valve controls the load precisely "all the way", from idling to full load.
Here is an unconventional PatTwo Harmonic engine:
With its single-piece double-acting piston, this two-cylinder engine has two combustions per crank rotation (i.e. as many as a 4-cylinder 4-stroke) and, in total, only three moving parts:
the first is a rotating, at constant angular velocity, power shaft,
the second is a rotating, also at constant angular velocity, intermediate shaft,
and the third is a reciprocating piston.
Among others, the Harmonic PatTwo engine is:
compact,
lightweight,
simple,
fuel efficient (it avoids subpressures at partial loads).
It has "four stroke like" lubrication.
It is as vibration-free as the Wankel Rotary engine.
Below the PatTwo Harmonic is shown stereoscopically from various viewpoints:
