MIT - The Way to Go...
March 2003 - MIT study says : Improving gasoline and diesel engines is
the way to go ! Hydrogen car is no environmental panacea. The hydrogen
fuel-cell vehicle will not be better
in terms of total energy use and greenhouse gas emissions by 2020. If we
need to curb greenhouse gases, improving mainstream gasoline and diesel
engines is the way to go.
These results come from an assessment of a variety of engine and fuel
technologies forecasting no real 'breakthroughs' (The Quasiturbine has
not been included in the study).
HCCI Detonation Engine
The Direct-Injection Spark-Ignition (DI-SI)
- The Direct-Injection Spark-Ignition (DI-SI) gasoline engine could become a reality
but will likely still use the intake vacuum of Otto cycle, and still
produce a non-uniform polluting combustion.
- The fuel-injection process in future compression-ignition engines
(CIDI or direct-injection diesels)
is difficult to achieve and is not yet commercial
It has also the main inconvenient to produce a "non-uniform polluting combustion"
like in Diesel engine.
