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
- Five engine platforms consist of 5- to 16-liter, four- or six-cylinder models ranging from 141 to 691 hp (105 to 515 kW)
- 16-liter, six-cylinder bi-fuel (natural gas and diesel) model available for power generation applications
