A delete kit is an OEM amendment package that removes or turns off emissions-associated components in a diesel engine. The ...

As state and federal clean-air regulators move forward with plans to further reduce nitrogen oxide and particulate matter emissions from commercial trucks, diesel engine makers are exploring new ...

SAE International Journal of Engines, Vol. 2, No. 1 (2009), pp. 77-82 (6 pages) ABSTRACT Automotive manufacturers and engineers have paid attention to promoting engine performance with low emissions ...

Cummins released details of its 2027 X15 diesel engine, which it says meets EPA 2027 emissions requirements while improving fuel economy — and without adding weight or using more diesel exhaust fluid.

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 ...

A team of engineers at the University of New South Wales (UNSW) in Sydney has figured out a way to run a diesel engine on a mix of diesel and hydrogen, dramatically lowering its emissions. Why do we ...

A retrofit system that converts diesel engines to operate on 90% hydrogen has been prototyped and tested by University of South Wales (UNSW) researchers. This system drastically reduces emissions of ...

NOx emissions from diesel vehicles, which have proven to be much higher in the real world than predicted in laboratory conditions, have even been blamed for tens of thousands of premature deaths. But ...

UNSW researchers have prototyped and tested a retrofit system that converts diesel engines to run on 90% hydrogen, radically reducing both carbon dioxide and nitrous oxide emissions while boosting ...
