Due to a combination of heavy taxes on fuel, particularly in Europe, tightening environmental laws, particularly in California, and the possibility of further restrictions on greenhouse gas emissions, work on alternative power systems for vehicles has become a high priority for governments and vehicle manufacturers around the world.
Current research and development is largely centered on “hybrid” vehicles that use both electric power and internal combustion.
Other R&D efforts in alternative forms of power focus on developing fuel cells, alternative forms of combustion such as GDI and HCCI, and even the stored energy of compressed air.
The use of alcohol as a fuel for internal combustion engines, either alone or in combination with other fuels, has been given much attention mostly…
