11.   However, most cars do not have catalytic converters to cut exhaust emissions, and unleaded gasoline was introduced to the country just last year.

12.   In LONDON, palladium rose amid increased demand for the precious metal from automakers that use it as a catalyst in devices that remove pollutants from exhaust emissions.

13.   Palladium is used by the electronic industry and is a component in automotive catalytic converters, which remove air pollutants from exhaust emissions.

14.   Precise fuel delivery is handled by electronic controls that help to enhance performance and reduce exhaust emissions.

15.   The climate control automatically recirculates the air when a pollution sensor detects a heavy concentration of exhaust emission in the outside air.

16.   The smelly, thick clouds of exhaust emissions from the vehicles would be a thing of the past, said June Deen of the American Lung Association.

17.   Turbodyne makes retrofit kits that cut exhaust emissions from vehicles, construction equipment and other devices operating on internal-combustion engines.

18.   World shortages of palladium and platinum are threatening to disrupt production of items such as catalytic converters, used to clean automobile exhaust emissions.

19.   World shortages are threatening to disrupt production of catalytic converters, used to clean auto exhaust emissions.
