Particulate Emission from Internal Combustion Engines

2018-5-28  Size distribution and number concentration of particles were measured by Electrical Low Pressure Impactor (ELPI). ELPI classifies particles considering their aerodynamic diameter. It combines the principles of electrical detection with size classification by impaction. A corona-wire diffusion charger is used to unipolarly charge the incoming particles. Next, the aerosol stream is introduced to a low-pressure cascade impactor where the particles are collected in 12 different stages depending on their aerodynamic diameter. In the first stage large PM particles with large quantity of kinetic energy collide into the first collecting plate and are trapped. Smaller PM particles have less inertia and are swept around the collecting plates to the next stage. In this way PM particles should be trapped in the impactor according to their size. Each impactor stage contains a sensitive electrometer that measures the current flow associated with the impacting particles.
