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

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 compared and recommendations made for future work.

Selected aspects of particle emissions are also investigated across a limited number of vehicles and fuels, but covering a wide range of vehicle technology and marketed fuel quality.
