Engine technology : Tier 4 Final D8 - G.W. Van Keppel

Volvo Tier 4 Final D8 - Smart technology.

The new D8 engine from Volvo Construction Equipment (Volvo CE) meets the Tier 4 Final emissions legislation, improves fuel efficiency by up to 5% and reduces overall running costs. The premium Volvo D8 engine delivers high torque at low rpm for superior performance and low fuel consumption.

The Volvo D8 Tier 4 Final engines incorporate selective catalytic reduction (SCR) plus DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate Filter) technology to meet the new emissions regulations. SCR uses an injection of diesel exhaust fluid (DEF) into the exhaust gas flow to create ammonia (NH3). The NOX and NH3 mixture gas pass through the SCR Catalyst where they react to form Nitrogen (N2) and Water vapour (H2O) to reduce emissions to a minimum. The ammonia slip catalyst, which is the last stage in the NOX reduction, oxidizes the excessive NH3 into N2 and H2O.

Volvo Trucks has used SCR since 2005 and Volvo CE has capitalized on the vast experience within the Volvo Group and the millions of hours of real-world testing to which he technology has already been subjected.

The Volvo Advanced Combustion Technology has been redesigned to incorporate an air intake throttle and specially coated DOC and DPF to achieve passive regeneration, which takes place regularly at low exhaust temperatures to oxidize particulate matter. Additionally, every 500 hours, particulate matter is incinerated at high temperatures via reset regeneration.

The Volvo D8 engine has been comprehensively tested and validated in both bench and multi-application field testing to ensure maximum performance, productivity and durability.
