Volvo Penta Tier 4 Final engines utilize selective catalytic reduction to reduce NOx and PM emissions without requiring a diesel particular filter.
- Diesel exhaust fluid injected reacts with NOx in the catalytic converter to turn it into nitrogen and water
- Light exhaust gas recirculation (light EGR) lowers peak combustion temperature
- Engine platforms consist of 5- to 16-liter, four- or six-cylinder models ranging from 143 to 700 hp
- Suited to various off-road applications including material handling, construction, quarrying, mining and agriculture
