The four-stroke engine cycle consists of four distinct phases: intake, compression, power, and exhaust. During the intake stroke, the engine draws in air and fuel. In the compression stroke, the mixture is compressed to increase its temperature and pressure. The power stroke follows, where the spark plug ignites the mixture, forcing the piston down, and finally, in the exhaust stroke, the spent gases are expelled from the cylinder. This cycle repeats to convert fuel into mechanical energy efficiently.

The Ottoman Cycle
In a two-stroke engine, two strokes is one cycle. In a four stroke engine, four strokes is one complete cycle. A stroke is a part of a cycle. Remember that the "up" motion and the "down" motion each count as one stroke.
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
Yes, "four cycle" and "four stroke" are the same. The two terms may be used to describe an engine. As a rule, the term "four stroke" is more commonly used.
The four strokes are... Intake, Compression, Combustion, Exhaust.

Four-stroke lawn mowers have a tube where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).

A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).
