The first Diesel engines were started 130 years ago, but they have moved a long way since then. Like their gasoline counterparts, the compression ignited engines have evolved from the rough units of ...

Detroit Diesel Corp. (DDC) just wrapped up the first demonstration of its in-use emissions test system on a 2004 model Series 60 heavy-duty diesel engine using a device installed on the truck itself.

In this study a new water injection system was applied to an 11 liter naturally aspirated DI diesel engine in order to reduce exhaust emissions. In this system, the water and fuel were arranged in the ...

Engine makers are also helping to curb emissions with items such as Eaton’s exhaust gas recirculation pump. Christy Roadknight, Eaton’s global product line manager, described a 48-volt electric pump ...

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 ...

Emission testing of combustion engines has thus been the focus of concentrated studies. in addition to the emissions comprising of nitrogen oxides (NOx), carbon monoxide (CO), particulate matter, and ...

The move from Tier 3 to Tier 4 Final diesel engines above 74 horsepower brought with it a whole grab bag of new components and systems – diesel particulate filters (DPFs), diesel oxidation catalysts ...

Cummins has instituted a voluntary recall of roughly 500,000 model-year 2010-2015 engines, according to an announcement from the U.S. EPA. The recall involves faulty emissions systems components that ...

The global aviation sector contributes approximately 5% of the current anthropogenic radiative forcing, owing to direct emissions of fossil-fuel CO 2 (28 mW m −2) and the formation and evolution of ...

Modifying cars for improved performance and style has always been a hobby with a bit of a rebellious streak. In the "good old days," it was pretty common for people to gut their car's catalytic ...
