  • Air as Clean as the Driven Snow

    While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two ...

  • Reducing Emissions Through Gas to Liquids Technology

    Gas to Liquids is a term that we are starting to hear more often, but what does it mean? Global Emissions Management looks at the need for new sources of transportation fuel, investigates current and planned activity in this key new technology area, ...

  • Brazil’s Flexfuel Experience

    Brazil maintains a dominant position in the South American automotive market, with an estimated two thirds share of thecontinent’s light vehicle sales, and 80% of production. The market has undergone significant changes in recent years however, ...

  • JM News

    Dr. Andy Walker, Johnson Matthey’s Heavy Duty Diesel Global Technology Director, is the winner of the Society of Automotive Engineers (SAE) 2006 Lloyd L. Withrow Distinguished Speaker Award. The award recognises the excellence and consistency of Dr. ...

  • Retrofit Schemes Around the Globe

    More than a decade on from the commercial introduction of Johnson Matthey’s Continuously Regenerating Trap (CRT®) technology, Global Emissions Management looks at how heavy duty diesel (HDD) retrofit schemes have developed during this period, and ...

  • Case No : 601: Reducing NOx emissions from Nirtic Acid Manufacturing Plants with NOx Abatement or NSCR

    NOx Abatement is a Non-Selective Catalytic Reduction (NSCR) technology that has a long and proven track record for controlling NOx emissions from nitric acid manufacturing plants. It can be used to alter the NO to NO2 balance (decolourization) or to ...

  • Advanced Threeway Catalysts

    One area of catalyst system design which has received relatively little attention is the method of application of precious metal, specifically with regard to its positioning in the catalyst. Recent advances in catalyst coating technology have ...

  • The Effect of Phosphorus and Boron Lubricant Oil Additives on Catalyst Durability

    With ever-tightening legislation driving down emissions limits, minimisation of catalyst deactivation is very important. Attention has now focused on chemical poisoning of three-way catalysts (TWC) by elements commonly found in engine oil. ...

  • New Non-Road Regulations in USA and Europe

    Earlier this year, the United States Environmental Protection Agency (EPA) introduced Tier 4 emissions standards for diesel engines in non-road mobile machinery (NRMM), which will come into force between 2008 and 2015.The European Union (EU) ...

  • Filters for Light Duty Diesels

    EA particulate filter can effectively eliminate tailpipe particulate emissions from diesel cars. Johnson Matthey’s work in this area has led to a new, third generation of catalysed diesel particulate filters that are highly durable and ...

  • Korea’s Resurgent Market

    With the effects of the financial crisis of 1997 behind it, the Korean motor industry is experiencing rapid growth both at home and abroad. Global Emissions Management assesses the Korean car market and the implications for the emissions ...

  • Ultra Low Emission Vehicle II Ultra Low PGM

    The task for the emissions management sector is to deliver cost effective solutions to meet future emissions standards. Global Emissions Management reports on catalyst development at Johnson Matthey demonstrating that ULEV II limits can be met ...
