HIGH MOLECULAR WEIGHT POLYSIOBUTYLENE DIESEL ENGINE COMBUSTION TECHNOLOGY IMPROVEMENT

摘要

Diesel engines are a primary source of power for transportation and in some parts of the world for the production of electric power. They are currently about 40% efficient in converting a fuel's energy to work. Diesel engines are also major emitters of NO_x and PM exhaust emissions. Leaner overall combustion could significantly increase diesel engine efficiency and reduce harmful exhaust emissions. Ultra high molecular weight polyisobutylene makes diesel engines run leaner by modifying the physical properties of the fuel to give it viscoelastic behavior.
