Two stroke engines are used in dirt bikes, ATVs, snowmobiles, etcetera. You can find them in most small recreational vehicles like that. A lot of outboard boat motors are also two stroke.
two stroke diesel engine is used in cargo ships as cross head type engines, two stroke petrol engines used in two wheelers.
The fuel used for both four stroke and two stroke engines is the same: gasoline. Two stroke engines require a small amount of two stroke oil be added to the fuel.
Two stroke engines are lubricated by mixing special two-stroke oil in with the petrol.
The difference between 2stroke engines and 4-stroke engines are pretty much the same regardless of where the engine is used. To read about it, check out the related question below.
Two stroke engines will create a lot of visible smoke pollution and also more noise than four stroke engines. For these reason, many countries have required that all new motorcycles should be four-stroke.

To deliver fuel and oil too the cylinder.
GM did make 2 stroke diesel engines used in trucks and busses..they were noisy, requierd a super charger to run, loved to drink but very powerful.
I think you are looking for a detailed engineering answer. Common usage is that a two stroke engines is called a two stroke engine. By the way my experience says that two stroke engines only have two strokes and the second one is fatal.
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).
There are a couple, less parts for one therefore lighter. Also, 2 stroke engines fire every time the piston comes to the top. Which means every stroke is a power stroke. 4 stroke engines fire every other time.
generally , two strokes are smaller capacity , shorter stroke, higher revs. for given engine capacity , long stroke /small bore = high torque / low revs short stroke/big bore = low torque / high revs
