Volvo Penta will use its tried and tested Selective Catalytic Reduction (SCR) technology for Indian OEMs when the stringent BS (CEV/Trem) IV emission regulations come into effect in October 2020. The SCR technology was first developed by Volvo Group in 2006. In 2011, Volvo Penta introduced the system for industrial off-road customers, further developing it in 2014. For original equipment manufacturers (OEMs), this means no re-generation, easy installation, continuous optimized fuel consumption and low operating costs.
For the Indian market, the current emission legislation applicable for off-road vehicles is BS (CEV) III from 2014, covering limited applications. Now, as announced by regulatory authorities, BS (CEV/Trem) IV will be enforced from October 2020 and will cover most of the off-road applications.
With the introduction of BS (CEV/Trem) IV, all engine manufacturers are required to introduce after-treatment systems for engines between 129kW to 560kW. This, in turn, will put enormous demands on OEMs, forcing them to re-design their machines to install new engines and after-treatment systems. Volvo Penta’s strategy is to keep these changes as simple as possible for Indian OEMs.
The SCR system is based on high-efficiency combustion, which reduces the fuel consumption and results in extremely
low levels of particulate matter (PM), but also in high levels of nitrogen oxides (NOx). Here, the ingenuity of the system is revealed: the exhaust NOx is converted into harmless nitrogen gas and water vapour.
The SCR system automatically injects diesel exhaust fluid/urea to the exhaust gases. The gases are then passed through
a catalytic converter before it is emitted to the environment. The extremely low levels of particulate matter in the
emissions also make exhaust gas filtration (DPF) unnecessary.
“We have extensive experience of SCR technology in the Volvo Group and we firmly believe that our BS (CEV/Trem) IV-compliant product range is industry-leading,” says Miron Thoms, Vice President & Head of Volvo Penta India. “We have been supplying BS (CEV/Trem) IV equivalent Stage IV/Tier4 Final engines globally since 2014 and have
more than 200 OEM customers.”
Volvo Penta is showcasing its BS (CEV/Trem) IV technology at the Volvo Group stall (OF-23) at bauma CONEXPO INDIA 2018, taking place at HUDA Ground, Gurgaon, Delhi between December 11–14.
