  • Controlling combustion noise in direct injection diesel engine through mechanical vibration measurement

    The next generations of direct injection diesel engines have greatly improved their performances compared with petrol engines. However, one of the pending subjects is the noise and vibration levels, due to working cycle itself. The design effort to reduce the emissions of noise and vibration transmitted to the vehicle's driver could be lessened because of the assembly process variation. In this ...

  • Switching from diesel to CNG or LNG fueled engines

    Gas engine fact: there are more than 28,000 engines in service in the refuse industry worldwide. Over the past several years, more and more American refuse companies have been considering the change from diesel to either CNG (compressed natural gas) or LNG (liquefied natural gas) fueled engines in their collection fleets. This article will discuss some components to consider before transitioning ...

  • CO2 benefit from the increasing percentage of diesel passenger cars in Switzerland

    One efficient way to decrease CO2 emissions is to replace gasoline passenger cars by diesel cars. The paper examines the benefit of CO2 emissions in the case of an increased diesel penetration in Switzerland, according to several scenarios assuming different future passenger car registrations and fuel consumption. The results show that a significant CO2 benefit can be achieved if a diesel ...

  • WHO report on diesel fumes puts sharp focus on need for effective monitoring

    The World Health Organisation this month reclassified the dangers of diesel exhaust fumes, upgrading the risk from probably carcinogenic to a definite cause of cancer. The WHO report is based on the findings of research on workers in high risk areas, and puts a sharp focus on the need for effective monitoring in industries such as mining, rail, transportation, construction, power generation and ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • U.S. headed for massive decline in carbon emissions*

    For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy. The United States has ended a ...
