When the high sulphur conversion kit has been used, the engines are able to run on high sulphur content fuel widely used in countries with lower emissions regulations for off-road vehicles. “The high sulphur conversion kit is a robust solution that allows customers to resell their machines into less regulated countries,” explains Jonas Andersson, product manager at Volvo CE Sales Region EMEA. “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 CE machines, including wheeled loaders, excavators, compactors and pavers. It is compatible with Volvo D4H, D6H and D8H medium-duty engines, and allows the use of fuels with a sulphur content of between 500ppm and 10,000ppm. The conversion process involves changes to both the hard and software of the engine. Six hardware kits and 28 new engine part numbers are needed to perform the conversion, and new software will be run separately at a Volvo back office to finalise the process when the physical changes have been made. The kit works by deactivating the exhaust gas recirculation (EGR) system and replacing the diesel particulate filter and diesel oxidation catalyst with a conventional muffler.
