Automotive particulate matter

Apr 1, 1998

Particulate matter (PM) in the air continues to be the focus of increased attention due to the concern of potential health effects. Accordingly, under the EU Air Quality Framework Directive an air quality standard has been defined with respect to PM10 (particulate...

A study of the number, size & mass of exhaust particles emitted from European diesel and gasoline vehicles under steady-state and European driving cycle conditions

Feb 21, 1998

Report no. 98/51: This study investigates the measurement of the mass and the number of light duty automotive (diesel and gasoline) exhaust particles and their related size distributions. Different analytical techniques for particle size determination are assessed and...

Proposed EU year 2000 gasoline volatility specifications

Apr 21, 1997

Report no. 97/53: A CONCAWE study identified the proposed flat maximum RVP limit across Europe to be of greatest concern within the gasoline volatility specification in the year 2000EU Draft Fuels Directive. The 60 kPa RVP defined for a six month summer period would...

Diesel fuel/engine interaction and effects on exhaust emissions. Part 1: diesel fuel density. Part 2: heavy duty diesel engine technology

Nov 21, 1996

Report no. 96/60: CONCAWE has investigated two major aspects of fuel/engine interaction and the resulting effects on exhaust emissions: • The impact of fuel density on the particulate emissions of a light duty turbocharged passenger car fitted with an advanced engine...

The measurement of the size range and number distribution of airborne particles related to automotive sources – a literature study

Apr 21, 1996

Report no. 96/56: This report reviews the literature relating to particulate size measurement and the techniques suggested for different applications. Successful measurements have been made using cascade impactors, which give gravimetric analysis of sized fractions...
