Suck, squeeze, bang, blow. :) Intake, compression, power, exhaust.
The upstroke of a two-stroke engine has only one function: compression. The downstroke is where power, then exhaust, then intake occur. This is the greatest animation I've seen for explaining a two-stroke engine: http:/www.animatedengines.com/twostroke.shtml
Yes
The crankshaft makes two complete revolutions to complete one thermodynamic cycle. The crankshaft rotates 180 degrees during each stroke of the engine. Hence a total of two revolutions occur after completion of the four strokes. Chechout "www.howstuffworks.com " to see how crankshaft works.
In a two-stroke engine, the crankshaft makes one complete revolution for each cycle of the engine. This means that during the intake and exhaust processes, both occur in a single revolution of the crankshaft. Consequently, each complete cycle of combustion and power generation is achieved with just one turn of the crankshaft.
Top dead center (TDC) refers to the position of a piston at the highest point in its cylinder. It can occur at the end of both the compression stroke and the exhaust stroke, depending on the engine cycle. During the compression stroke, the piston moves upward toward TDC, compressing the air-fuel mixture before ignition. Therefore, TDC is not exclusively the compression stroke; it is a position that can be reached at different points in the engine cycle.
In a two-stroke cycle engine, the crankshaft completes one full revolution to complete one thermodynamic cycle. This is because two strokes of the piston (one upward and one downward movement) correspond to one crankshaft revolution, allowing for both the intake and exhaust processes to occur within that single rotation.
Your 4 strokes are Intake, Compression, Power, and Exhaust. On the first revolution is Intake on the down stroke, then compression on the up stroke, the next revolution is power on the down stroke and exhaust on the up stroke, so 2 revolutions complete a full cycle. That would mean 450 power strokes occur per minute, divide that by 60 to get 7.5 power strokes per second

No Hitters Hitting for the cycle Breaking a record
A sequence of events that repeats itself is known as a cycle or a loop. This repeating pattern can occur in various contexts, like nature, mathematics, or programming.
Two stroke engines have one power/exhaust stroke and one intake/compression stroke per revolution per cylinder. A One cylinder engine at 900rpm produces 15 power strokes per second.
The scientific definition of a cycle is where a series of events occurs that affects each other event, and goes in a "cycle" and repeats. A cycle is a recurring series of successive operations or states, as in the working of an internal combustion engine, or in the alternation of an electric current or a wave.
