Emission Reduction Systems

Emissions from the tailpipe are most harmful to the public at highway speeds, while crankcase emissions effect students, drivers and teachers at idle. That is why we have worked with school districts and federal agencies to provide emission reduction solutions for both the bus tailpipe and the crankcase.

Tailpipe emission solutions:

Diesel Multi-stage Filter (DMF) Mufflers

Diesel Oxidation Catalysts (DOC)

Diesel Particulate Filter (DPF)

Crankcase emission solution:

Closed Crankcase Ventilation Filter (CCVF)/Spiracle

At idle, most emissions come from the crank case.

At highway speed, most emissions come from the tailpipe.
