Small displacement Motor cycle engines often have a Rev Limiter in the ignition system
Most industrial engines have a govener incorporated.
two stroke diesel engine is used in cargo ships as cross head type engines, two stroke petrol engines used in two wheelers.
Petrol, carburettor Petrol, fuel injected Both can be normally aspirated or turbo charged Petrol two stroke Diesel, Normally aspirated or turbo charged Diesel, two stroke Rotary engine.
four stroke / petrol Nowadays they use V8 2.4 litres engines but there are plans to change to V6 turbocharged engines starting from 2014.
Turbochargers are used on some petrol or gasoline engines.
Fuel oil is thicker than petrol because it has a higher viscosity and density. Fuel oil is used in heating systems and diesel engines, while petrol is used as a fuel for gasoline engines in cars.
They are - most inboard engines are 4-stroke. But as with land vehicles, you can get a smaller engine with 2-stroke (or more horsepower with a smaller engine) so the small engines like some outboards tend to be 2-stroke.
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.
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.
They can be. Petrol engines can be either fuel injected, or have carburetors. Smaller engines, like scooters, lawnmowers etc are almost always carburetted, while car engines are usually fuel injected these days.

Since water doesn't burn like petrol, it's far less useful to power engines with.
