Well here we go again. I will start another argument with the "Experts"in which I will not participate.

The term 4-cycle (or 2) is incorrect when describing engines. A cycle is a complete set of events. Kind of like the seasons in a year, get it?

A four stroke engine has four piston strokes and two crankshaft revolutions per cycle. It does not have four cycles.

If the engine is called a "Four cycle" engine does this mean that it cycles only four times? That is sixteen piston strokes, eight revolutions. Then what?
It can be seen how incorrect this description is. Or is it too complicated for the "Experts" to grasp.

It could be claimed that every reciprocating internal combustion engine on the planet is, in fact, a one cycle engine. Although I am sure there must be some exceptions!!
