Stage V: Optimized for Tomorrow
Engine and construction equipment manufacturers are facing their toughest emissions challenge yet with the release of new EU Stage V emissions legislation coming into force this month. Volvo CE will be delivering maximum power and performance with new engine technology that is one further step towards a more sustainable tomorrow.
Stage V introduces particulate number (PN) limits for all manufacturers of engines between 19 kW and 560 kW, requiring diesel particulate filters (DPF) to be part of the EATS on the engine installation in the machines. In addition, there will be an increased focus on emissions during the machine’s usage.
For engines with a powerband bigger than 130 kW and less than 56 kW, the limits came into effect from January 1st 2019. But for engines with a powerband between 56-130 kW, the legislation will come into force a year later on January 1st 2020. Volvo CE is already ahead of the game for these engines, since the company took the decision to introduce Stage V engines across both powerband ranges as early as the beginning of this year.
Mats Andersson, Vice President Marketing & Sales Support for Sales Region EMEA, at Volvo CE, says: “Manufacturers are under increased pressure to ensure engines adhere to the most stringent emissions standards and this new EU regulation is the toughest yet. However, with the swift introduction of Stage V-compliant engines, Volvo CE has proved that it is committed to building a more sustainable future for its customers today.”
The sophisticated Stage V range has been built not only to meet these stringent requirements, but to provide a number of benefits for OEMs and operators. These include:
- Productivity: optimizing power to maximize customer use and provide good ROI.
- Uptime: ensuring that the engine is robust, reliable, and easy to service.
- Cost of ownership: minimizing fuel consumption and maintenance costs.
- Sustainability: reducing emissions for environment care and regulations compliance.
The competitive solution will effectively be the same as for existing Stage IV engines, except that DPF is now required on machines with engines between 19-36 kW.
The highly advanced system has undergone extensive tests in the toughest of operational conditions to ensure it meets customers’ needs for today and tomorrow. The new and improved system provides for a charge air cooler, which cools the inlet air for better efficiency, and either a variable geometry turbo (VGT), designed to optimize the air-fuel ratio in the turbo to be altered as conditions change, or a fixed geometry turbo with waste gate (WG). A DPF has been designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine, while a diesel oxidation catalyst (DOC) serves to oxidize hydrocarbons and carbon monoxide into carbon dioxide and water.
Passive regeneration of the aftertreatment system eliminates unplanned stops during operation. Current tests show that there will be no need for stand-still regeneration under normal operational conditions; the exhaust temperature is automatically maintained at an optimum level.
Finally, the exhaust gas recirculation feature – both cooled and uncooled – reduces emissions by recirculating a portion of exhaust gas back into the engine.
With fuel efficiency and maximum uptime a key consideration for Volvo CE, customers can be confident that their machines meet the strictest of emissions standards and have been fully optimized for tomorrow’s needs.
Volvo CE uses the latest technology from across the Volvo Group in order to best serve its customers. OEMs and operators can also be sure that their needs will be met through the company’s global aftermarket service network.
