The result is cleaner combustion with low NO x and soot emissions. To realize ideal combustion timing and duration as well as clean emissions at the same time, Mazda uses this premixed compression ignition combustion by controlling ignition timing based on model-based prediction of ignition delay in the low compression ratio engine.

While the latest Euro VI buses and advanced electrified options comfortably meet clean emission requirements, a significant majority of the older, existing bus fleet are seen as being a significant source of pollution and need a rapid and cost-effective solution.

Further understanding and characterization of the underlying physical and chemical mechanisms of PM formation in DI combustion systems is critical to achieving clean emissions. The researchers also used a smoke meter to measure particulate emissions in the engine exhaust gas. —Fatouraie et al.
