A Demonstration of Transit Bus Particulate Traps in Ottawa Ontario 952651

Heavy-duty diesel engines for transit bus applications are having to meet increasingly stringent emission standards. The new engines are significantly cleaner than they were just a few years ago. However, due to the long life of transit buses in Ontario (18 years), many buses still in service are powered by older engines which produce greater amounts of regulated exhaust emissions.

The Ottawa-Carleton Regional Transit Commission (OC Transpo) has an interest in reducing emissions from older transit buses in their fleet. Eight Donaldson particulate trap systems were installed on transit buses. The purpose of the work, involving four different bus/engine combinations, was to assess the practicality and benefits of particulate traps in transit applications.

This paper discusses the demonstration of diesel exhaust particulate traps in Ottawa-based transit buses. Installation details and extensive operational information are discussed, including capital and maintenance costs, emission test results, trap system maintenance requirements, vehicle reliability, and trap system durability.
