European Technology for Reducing Exhaust Pollution from Naval Ship Engines

摘要

In response to the world wide interest in reducing air pollution, the U.S. Navy is studying methods for lowering emissions from new, as well as existing, ship engines. As part of those studies, this report summarizes an examination of the science and technology base in Europe related to marine engine combustion and emissions. On site visits in 1995 found a strong theoretical and bench scale science capability, as well as considerable facilities for full scale engine operation and diagnostics. Activities on the part of the owner/operator community were found to be diverse, with some aggressively pursuing low emission engines, while others were delaying action until the international regulatory situation clarified. It is concluded that the European science and technology base for the reduction of ship engine emissions is quite good, due in large part to prior work in support of European Community and national programs to reduce exhaust pollution from land vehicles and aircraft. The technology is believed to be adequate to provide realistic options for meeting foreseeable international regulations on exhaust emissions from naval ships.
