Every little bit of efficiency a fleet can squeeze out of engines can go a long way in maintaining a healthy profit margin. Even for fleets that spec the latest in aero kits, low rolling resistant ...

Diesel exhaust contains a lower level of hydrocarbons, which serve as the reductant for the NOx catalyst, than gasoline engine exhaust. An investigation was made of several methods for maximizing the ...

The paper describes research and development work concerning the investigation and optimization of lean NOₓ catalysts for gasoline and diesel engine applications. The investigations carried out in the ...

Modern diesel engines are engineering marvels of power and efficiency — but they also come with a complex web of emissions ...

WEST LAFAYETTE, Ind. – Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution-control systems to further reduce emissions of smog-causing ...

Today's catalysts for removing unburnt methane from natural-gas engine exhaust are either inefficient at low, start-up temperatures or break down at higher operating temperatures. A new single-atom ...

A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the ...

(Nanowerk News) A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs ...
