Evaluation of a Catalyzed Ceramic Diesel Particulate Filter and Catalytic Converter on an Underground Mine Vehicle
The U.S. Bureau of Mines (USBM) and Diesel ControlsLimited are evaluating a new diesel emission control system on an underground mine vehicle. The system is a catalyzed ceramic wall-flow diesel particulate filter (CDPF) combined with an oxidation catalytic converter (OCC). It is the first installation in the U.S. of a CDPF on a mining vehicle with a turbocharged engine at a high altitude mine, ...

Evaluation of diesel fleet emissions and control policies from plume chasing measurements of on-road vehicles
Abstract Vehicle emissions are an important source of urban air pollution. Diesel fuelled vehicles, although constituting a relatively small fraction of fleet population in many cities, are significant contributors to the emission inventory due to their often long mileage for goods and public transport. Recent classification of diesel exhaust as carcinogenic by the World Health Organization ...

Analyses of technical options for mitigating CO2 emissions from an urban transport system: a case study of Beijing City
This paper aims to extrapolate the energy consumption and environmental emissions data on the urban passenger transport system in Beijing, to assess the cost-effectiveness and emission reduction potential of promising technology options for transport systems, and to identify options with both reduction potential and cost-effectiveness. Furthermore, it identifies major barriers to the adoption of ...

School bus retrofits one local air
The Hamilton County Department of Environmental Services, a local air agency covering the Greater Cincinnati Area in Southwest Ohio, has experienced many successes and failures obtaining grant money to fund school bus retrofits. However, seven years of persistent work has paid-off enormously. The adverse health effects of diesel exhaust were making national headlines in the early 2000s. The U.S. ...

Emissions reduction with Diesel blending
Diesel technologies are develops by huge rates. Modification of cars with diesel engines make a half of the new cars sold in Europe. The black smoke, noisy engine operation and unpleasant smell remained far in the past. Today diesel engines present not only profitability, but also high capacity and worthy dynamic characteristics. Quality of fuel also is changed. The modern diesel blending has ...

Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —
Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM ...

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 hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. Though situated at an ...

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 ...
