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. ...

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 cost optimised. They have the potential of providing significant health benefits through elimination of particulate emissions into the environment, ...

In-Mine Field Trials of a Particulate Filter System with On-Board Electrical Regeneration
ABSTRACT The need to improve air quality in many North American mines is clear, with stringent new diesel emission regulations being proposed by MSHA. In response to these changing demands from customers, DCL has developed an electrically heated active sootfilter regeneration system for mining vehicles. Mining production vehicles that have often been borderline soot filter applications in the ...

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, ...

Predicting Diesel Particulate Filter Performance
The diesel particulate filter (DPF) has been used for many years in the control of diesel particulate matter (DPM)emissions. This technology is characterised by extremely high efficiency and high sensitivity to the application conditions. Research and testing performed by Diesel Controls Ltd. over the past two years has resulted in improved methods for predicting the application based performance ...

Maritime emissions treatment system (METS)
In January 2014, the California Air Resources Board (CARB) began enforcement of the "Airborne Toxic Control Measure for Auxiliary Diesel Engines Operated on Ocean-Going Vessels At-Berth in a California Port" Regulation, commonly referred to as the At-Berth Regulation. Covering all six ports in California, the At-Berth Regulation requires a 50% reduction in emissions from auxiliary diesel engines ...

New Filtration Systems for the Control of Exhaust Emissions from Light-Duty Diesel Engines
The paper includes the design, installation and testing of two different diesel particulate filter systems for light-duty diesel engines. The systems were installed on mining vehicles at Kidd Creek Mine in Timrnins, Ontario, Canada. The first system utilizes a newly developed pleated-media filtration element. The filter must be cleaned off-board or replaced with a new unit after a duty cycle. ...

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 ...

Suppression of particle deposition onto downstream wall in an AC Electrostatic Precipitator with neutralisation
Electrostatic Precipitators (ESPs) are used to decontaminate polluted environment around the tunnels. A conventional ESP has high collection efficiency but still has a problem in that its downstream walls are polluted due to particle deposition. The experiments carried out in this study have focused on how the particle deposition can be prevented by neutralising the gases. The collection ...

Black Soot, Diesel Exhaust and Indoor Air Quality
What do diesel exhaust particles, black soot, carbon black and diamonds have in common? Answer: They are all forms of the element, Carbon! While diamonds may be a girl’s best friend, diesel exhaust particles and black soot surely aren’t. It’s the difference between black (Carbon) and white (Carbon)!!! We’ve all seen black smoke belching from big rigs on the highway. Some ...

On-road tests show gas trucks up to 5 times worse for air pollution
Trucks powered by liquified natural gas (LNG) pollute the air up to five times more than diesel trucks, according to on-road tests commissioned by the Netherlands government. The results fly in the face of truckmakers’ claims that gas trucks cut nitrogen oxide (NOx) emissions by more than 30%.[1] [2] Transport & Environment (T&E), which today publishes the test results, ...
