Sentences with phrase «improve catalytic efficiency»

Not exact matches

April 5, 2018 - The new materials, known as high - entropy - alloy nanoparticles, have created unprecedented catalytic mechanisms and reaction pathways and are expected to improve energy efficiency in the manufacturing process and lower production costs.

As discussed above, nano - engineered materials in automotive products include polymer nanocomposites structural parts; high - power rechargeable battery systems; thermoelectric materials for temperature control; lower rolling - resistance tires; high - efficiency / low - cost sensors and electronics; thin - film smart solar panels; and fuel additives and improved catalytic converters for cleaner exhaust and extended range.

This guarantees improved operating efficiency for team engineers and a general lowering of temperatures, thanks to the cooler and more efficient catalytic converters.

* Horsepower and torque expected to top previous model (testing is ongoing — check media.gm.com for updates) * NOx emissions reduced at least 63 percent over 2010 models * Quieter operation * High - pressure (30,000 psi / 2, 000 bar) Piezo - actuated fuel system for greater fuel efficiency, improved performance and reduced emissions * Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes * Selective catalytic reduction after - treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance — with a range of about 5,000 miles (8,000 km) between DEF refills * Combustion and after - treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations — a 75 - percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel * B20 biodiesel capability for an alternative fueling option * Internal revisions that improve durability

The layout enables the convertors to quickly heat up, which facilitates catalytic activation during engine startup and improves on emission reduction efficiency.
