Grant supports the development of a diesel smoke cleaning device for marine vehicles


Professor of Mechanical Engineering at UC Riverside Heejung jung received a grant from the National Science Foundation in collaboration with Stephen Cronin at the University of Southern California to study the fundamental mechanisms of plasma-enhanced electrostatic precipitation of diesel particles to clean up emissions from ships, ferries and large ships . USC is leading the effort, although the $ 420,000 grant is split evenly between the two institutions.

“While diesel particulate emissions are well controlled and regulated for ground applications such as off-road vehicles and equipment, the majority of medium and large-sized marine diesel engines still emit a lot of diesel particulate into the atmosphere. due to the lack of appropriate control technology and less stringent regulations, ”Jung explained.

Diesel particulates, also known as carbon black, are carcinogens and air pollutants that warm the planet. Electrostatic precipitation uses an unfiltered device to remove fine particles from an incandescent plasma, a gas of free ions and electrons, using an electrostatic charge. Prototypes of the team’s devices showed significant improvement in diesel particulate attenuation over conventional electrostatic precipitators

Jung aims to understand the fundamental mechanisms of plasma-enhanced electrostatic precipitators for marine applications.

“Our team aims to clean diesel particles from the atmosphere over oceans and in ports around the world with this device,” he said.
