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. ...

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 ...

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 ...

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 ...

Deluged by Diesel: Healthy Solutions for West County
Hugging the San Francisco Bay, in the shadow of a major oil refinery, and surrounded by industry, freeways, and rail yards, sits the community of Inner West Contra Costa County. As this report will show, the residents of this area (which we will call Inner West County for the sake of simplicity) are exposed to far more than their fair share of pollution. However, the good news is that there ...

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, ...

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. ...
