Motorcycle Unregulated Emissions Report
Download: ACEM Motorcycle Unregulated Emissions Report
Link: ACEM Environmental Policy
Although a considerable base of expertise exists in member companies in the field of regulated pollutants (CO, HC and NOx), very little is known about the currently unregulated pollutants that make up smallest fractions of motorcycle exhaust emissions.
In 2001, ACEM member companies expressed a wish to explore this important aspect of their products and this report is the result. The main purpose of the report is to expand the collective knowledge of ACEM members in the field of currently unregulated exhaust emissions across a variety of typical motorcycle types.
It should also be noted that this report is the result of a collaborative arrangement, which was made with two knowledgeable and respected external bodies.
These are the UK Department for Transport, Local Government and the Regions (DTLR) and Ricardo Consulting Engineers of Shoreham by Sea, UK.
ACEM co-operation with DTLR was requested in support of a programme of motorcycle test work which DTLR conducted. ACEM member companies contributed motorcycles for test to the DTLR programme, which was conducted at Ricardo’s Shoreham laboratories.
The unregulated test data stemming from the DTLR programme was purchased from DTLR by ACEM. ACEM wishes to point out that the report, analysis of results and opinions expressed are strictly those of ACEM and do not in any way constitute the analysis conclusions or opinions of DTLR.
This report contains five chapters and three appendices.
Chapter 1 is the current chapter where ACEM explain the reasons for the project and the external bodies involved.
Chapter 2 describes the health and air quality effects of each unregulated pollutant balanced against recommended levels for human health & summarises the potential for future legislation on unregulated emissions of motorcycles.
Chapter 3 lists the pollutants measured in the programme, gives a key to each of the test methods and defines the test cycle used. It goes on to show comprehensive details of the test results for the full spectrum of unregulated emissions from each motorcycle.
Chapter 4 summarises some of the emissions reduction techniques available to motorcycle manufacturers for both regulated and unregulated emissions.
Chapter 5 provides a summary of ACEM conclusions drawn from the details contained in the body of the report.
ACEM regard the report as a first step in building knowledge of unregulated pollutants within the motorcycle industry. Although the pollutants measured are currently unregulated, ACEM regard knowledge of the subject as an important step in making motorcycling an environmentally friendly mode of transportation. We look forward to furthering knowledge of this subject in the future.
