On Road Particle Emissions of a Diesel Car Fueled with Coal to Liquids

Abstract:

Particle emissions of a diesel car fueled with coal to liquids (CTL) on road were tested. The particle number and size distribution were mainly studied. Three typical roads were adopted in this test, including urban arterial roads, secondary roads and freeways. The results show that transient particle number of the car has a corresponding relationship with the vehicle speed. With the speed increasing, the number of both nucleation mode particles and accumulation mode particles increase continuously. With the CTL blend ratio increasing, the number of nucleation mode particles and accumulation mode particles decreases, especially accumulation mode particles whose size are more than 100nm diameter. With the CTL blend ratio increasing, the particle numbers in the three typical roads show downward trends, especially on freeways. It shows that the CTL fuel can distinctly reduce the exhaust particle number of diesel cars on road.
