Increasingly stringent federal emission standards for diesel engines have become a major headache for trucking. Like most new technologies, the post-October 2002 emissions controls have their share of ...

Manufacturers continue to develop advanced technologies that aid in the improved operational efficiency of heavy-duty commercial vehicles. This effort has been a priority for vehicle suppliers and ...

When boiler equipment does not meet state or federal emissions requirements, operators may require after-treatment systems. After-treatment systems contain emissions control catalysts, depending on ...

Today's diesel engines use selective catalytic reduction (SCR), an advanced emissions control system, to abate NOx emissions. DEF is injected into the exhaust stream and ideally decomposes to form ...

The variable valve timing (VVT) system has become commonplace in automotive manufacturing. Automotive VVT system improves fuel economy and performance of vehicles. The have become a key mechanism to ...

There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

The efficiency and long-term performance of an SCR System is largely dependent on several key design considerations of the various equipment within the SCR System. When complex NOx reductions on ...

Power management company Eaton Corp. announced a series of 48-volt technologies to assist its global on- and off-highway commercial vehicle customers transitioning from traditional 12- and 24-volt ...

The U.S. Environmental Protection Agency has proposed tougher nitrogen oxide (NOx) emissions limits for new, modified, and reconstructed stationary combustion turbines. The proposed rule identifies a ...
