Complete Engines
Engine displacement is defined as the total volume of air/fuel mixture an engine can draw in during one complete engine cycle; it is normally stated in cubic centimetres, litres or cubic inches. more...

In a piston engine, this is the volume that is swept as the pistons are moved from top dead centre to bottom dead centre.
Governmental regulations
In many nations levels of taxation on automobiles have been based on engine displacement, rather than on power output. Displacement is easy to identify and difficult to modify whereas power output must be tested. This has encouraged the development of other methods to increase engine power.
There are four major regulatory constraints for automobiles: the European, the British, the Japanese, and the American. The method used in some European countries, and which predates the EU, has a level of taxation for engines over one (1.0) litre and another at the level of about 100 cubic inches, which is approximated to 1.6 litres. The British system of taxation depends upon vehicle emissions for cars registered after 1 March 2001 but for cars registered before this date it depends on engine size. Cars under 1549 cc qualify for a cheaper rate of tax .
The Japanese is similar to the European taxation by classes of displacement, plus a vehicle weight tax. In the American system, which includes Canada, Australia and New Zealand, there is not this sort of taxation per engine displacement. In The Netherlands and Sweden, road tax is based on vehicle weight.
Displacement is also used to distinguish categories of (heavier) motorbikes with respect to license requirements. In France and some other EU countries, mopeds, usually with a two-stroke engine and less than 50 cm3 displacement can be driven with minimum qualifications (previously, they could be driven by any person over 14). This led to all light motorbikes having a displacement of about 49.9 cm3. Some people tuned the engine by increasing the cylinder bore, increasing displacement; such mopeds cannot be driven legally on public roads since they do no longer conform to the original specifications and may go faster than 45 km/h.
Wankel engines, due to the amount of power and emissions they create for their displacement, are generally taxed as 1.5 times their actual physical displacement (1.3 litres becomes 2.0, 2.0 becomes 3.0), although actual power outputs are far greater (the 1.3 litre 13B can produce power comparable to a 3.0 V6, and the 2.0 litre 20B can produce power comparable to a 4.0L V8). As such, racing regulations actually use a much higher conversion factor.
Example regulations
Brazil: under 1000 cc, from 1000 to 1999 cc and more than 2000 cc for passenger vehicles. As of October 2006, 56.4% of the cars sold in the Brazilian market were under 1000 cc and only 1.3% were over 2000 cc.;
Bulgaria: a special tax on non-European cars over 2.8 L, later amended to over 3.0 L;
Belgium and Portugal have a proportional tax including reference to displacement;
Ireland: There is one rate for cars under and including 1000 cc, then rates increase by increments of 100 cc up to 3000 cc - 3001 cc and higher are all charged the same. Goods vehicles are taxed by weight, buses are taxed by the number of passenger seats (except school buses which are charged a small flat rate).;
Korea: under 0.8 L; 0.8-2.0 L; over 2.0 L;
Netherlands: progressive proportional tax based on vehicle weight, fuel type and region.;
Philippines (proposal from 2000): under 1.6 L; 1.6-2.0 L; 2.0-2.8 L; over 2.8 L;
Poland excise tax not compatible with EU regulations: engines up to 2000 cc have 3.1% tax, over 2 litres have about 13.6% tax;
Spain: under 1.6 L; over 1.6 L;
Taiwan: < 500 cc, 500~600, 601~1200,... Displacement tax is grouped by 600 cc increments up to 8400cc. The majority of registered vehicles fall in the 1200~1800cc and 1800~2400cc category. There is a significant tax difference in annual taxes (fuel and registration added together) for cars displacing over 3001 cc and the category before it; cars of this class are considered upscale luxury or performance cars.;
