Diesel exhaust particles carry a significant electrical charge. Until recently this charge was viewed primarily as a nuisance which made accurate sampling and characterization of the particles more difficult. However, the presence of this charge may be of importance for other reasons: a) it gives new insights into high temperature particle charging, b) it may help us to understand the particle formation process itself, c) it may make it possible to build simple sensors for feedback control of diesel engines, and d) it may make it possible to build coronaless electrostatic traps for diesel particle emission control. This paper examines a), b), and c) briefly.
