The Volvo Penta Tier 4 Final engine range for off-road applications consists of five basic engines
Volvo Penta introduced its range of engines compliant with Tier 4 Interim/Stage 3B, all based on the Selective Catalytic Reduction (SCR) technology in Janaury 2011, and while they were well received by the market, the off-road equipment industry was aware that within less than three years they had to go from the Interim stage to the Final stage, a substantial 80% reduction of the NOx – from 2.0 g/kWh to 0.4 g/kWh,” says Volvo Penta.
“They were also facing the additional challenge of re-designing their machines for installing new engines and after-treatment systems from their suppliers.”
To meet the new, stringent emission requirements of Tier 4 Final, and using the SCR technology, Volvo Penta says its new Tier 4 Final engine range will meet customers’ primary objectives: no re-generation, limited installation challenges, continuous optimised fuel consumption and low operating costs. With as few and as simple changes as possible.
The company says the “light” EGR [exhaust gas recirculation] system added to the engines has provided further emission reduction.
“It will, at the same time, help keep the SCR catalyst operating at an optimal temperature. By avoiding a costly Diesel Oxidation Catalyst (DOC), installation is greatly simplified,” says the company.
The Volvo Penta Tier 4 Final engine range for off-road applications consists of five basic engines, which will be on display at
Volvo Penta will also introduce the new, automatic start/stop function for industrial equipment, which turns off an idling engine after a pre-set time span, and when the driver activates any machine control the engine starts immediately and the work can continue.
For the mining industry Volvo Penta has a new range of engines approved for underground mining applications: nine Tier 2 engines and nine Tier 4i engines.
