Transient Plasma Systems says advances are bringing plasma ignition technology closer to commercialization

Green Car Congress

TPS technology has been shown to improve fuel efficiency by as much as 20% at low load points (such as highway driving) and 10-15% over an entire drive cycle. The TPS solution is not expected to need regeneration, unlike conventional diesel particulate filters (DPF), greatly reducing maintenance and improving regulatory compliance.
