Volvo Construction Equipment has launched kits which allow machines fitted with European Stage IIIB-compliant engines to be ‘de-tiered’ for sale as used machines in lesser regulated markets.
The modification is necessary, as diesel with very low sulphur content tends not to be available outside highly regulated markets like Europe, Japan and the US. Ultra-low sulphur diesel is essential for equipment fitted with Stage IIIB and higher emissions control systems.
The systems available from Volvo are for its four, six and eight cylinder (D4H, D6H and D8H) medium duty engines from about 100 kW to some 385 kW. They allow the engines to run on fuel with as high as 1,000 parts per million (ppm) of sulphur.
The conversion process involves a physical change to the engine as well as a software update. The kits work by deactivating the exhaust gas recirculation (EGR) system and replacing the diesel particulate filter and diesel oxidation catalyst with a conventional muffler. Once completed, the conversion is permanent and the engine cannot be used in regulated markets.
These changes are made by the dealer in the less regulated market, in conjunction with Volvo parts department. Approval for the conversion will be given when the dealer has updated the engine with the latest software and removed the Stage IIIB compliance certification labels.
“The high sulphur conversion kit is a robust solution that allows customers to resell their machines into less regulated countries,” said Volvo Construction Equipment sales manager for the Europe, Africa & Middle East sales region, Jonas Andersson. “The kit is installed using genuine Volvo software and hardware, ensuring the quality and reliability of the machines are not affected when the engine is converted. This conversion extends the longevity of the machine and its components, and is quickly and easily implemented by dealers.”
The conversion kit is available for a range of Volvo machines, including wheeled loaders, excavators, compactors and pavers.
