The new D8 engine from Volvo Construction Equipment (Volvo CE) meets the Stage IV 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 Stage IV 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 AdBlue® solution into the exhaust gas flow to create ammonia (NH3
). The NOX
mixture gas pass through the SCR Catalyst where they react to form Nitrogen (N2
) and Water vapour (H2
O) to reduce emissions to a minimum. The ammonia slip catalyst, which is the last stage in the NOX
reduction, oxidizes the excessive NH3
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 the 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.
Top features of D8 engine include:
Volvo Construction Equipment engineers are experts at optimizing the integration of the engine and the machine – both are developed by Volvo and perfectly matched to all the applications the equipment operates in.
