Potential of Diesel and Gasoline Engines to Meet Future Environmental Requirements
Published May 14, 1992 by Societe des Ingenieurs de l'Automobile in France
The aspects covered show clearly that a high fuel consumption and emission reduction potential with gasoline and diesel engines exist. For the years to come the following prognoses can be given:
-With a presented technology for gasoline and diesel engines it should be possible to meet the severe TLEV and LEV emission values of California and for gasoline engines also the ULEV emission values.
-Gasoline engines for passenger cars have a potential for fuel consumption reductions of up to 25% against today's best engines.
-Diesel engines for passenger cars have a potential for fuel consumption improvement of up to 20%.
-Additional improvements on passenger cars should result in a consumption improvement of about 40 to 50% and thus, lead to a substantial reduction of CO2 - exhaust emissions.
-Gasoline and diesel engines are suited perfectly for so-called "clean" fuels like natural gas or methanol efficiently produced from natural gas, or hydrogen.
-A consideration of primary energy usage and toxic emissions, globally as well as locally, shows that in the next 20 years there is no real alternative to the combustion engine
