Dec 21, 1994

Report no. 94/59: Ten European vehicles, meeting the requirements of the EU ‘Consolidated Emissions Directive’, have been tested on a matrix of seven gasolines over the current ECE+EUDC test cycle. The programme was designed to investigate the effects of...

Review of European oil industry benzene exposure data (1986 – 1992)

Nov 21, 1994

Report no. 7/94: This report summarizes over 2,000 occupational exposure data on benzene,measured in the period 1986-1992. Exposures for the various types of jobs are reviewed against a number of timeweightedaverage (TWA) criteria, including 1 ppm and 0.5 ppm. Most of...

Diesel fuel emissions performance with oxidation catalyst equipped diesel passenger vehicles – Part I

Sep 21, 1994

Report no. 94/55: This study confirms the very effective control of diesel exhaust particulate, carbon monoxide and hydrocarbon emissions with oxidation catalyst technology. In addition, the investigation documents the ability of an exhaust oxidation catalyst to...

A review of analytical methods for the quantification of aromatics in diesel fuels

Aug 21, 1994

Report no. 94/58: The definition of “aromatics” in diesel fuel has caused difficulties, both within the oil industry and amongst other interested parties. By virtue of the boiling range of the fuel, the majority of its hydrocarbons will have between ten...
