Volvo Penta to 'keep it simple' for Indian OEMs ahead of BS (CEV/Trem) IV emission regulations 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, which was first developed by Volvo Group in 2006, was introduced by Volvo Penta in 2011 for industrial off-road customers, and further developed in 2014. The same technology will now be used to comply with the BS(CEV/Trem) IV emission regulations, effective October 2020. ForOEMs, this means no re-generation, easy installation, continuous optimized fuel consumption, and low operating costs.

For the Indian market, the current emission legislations 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 cover most of the off-road applications. 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. Volvo Penta’s proven SCR technology complies with BS (CEV/Trem) IV emission regulations without using a separate diesel particulate filter (DPF) or diesel oxidation catalyst (DOC).

The SCR system is based on highefficiency combustion, which reduces fuel consumption and results in extremely low levels of particulate matter (PM) and in high levels of nitrogen oxide (NOx). Here, the ingenuity of the system is revealed: the exhaust NOx is converted into harmless nitrogen gas and water vapor. 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 MironThoms, 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 who are extremely pleased with the competitive advantages of these engines such as no regeneration, easy installation, as well as low operating costs."

Volvo Penta has engines that meet all emission standards, so, OEMs already using Volvo Penta BS (CEV) III engines will have no trouble changing to a BS(CEV/Trem) IV model, as the SCR catalyst will simply just replace the current silencer. It will also allow for lesser regulated export markets to be served without need of engine room re-design, and can be considered future-proof against the inevitable BS (CEV/Trem) V regulations.

Volvo Penta, which has recently supplied its engines to Indian crushing equipment major Puzzolana Machinery Fabricators through our GOEM for its tracked crushing and screening solutions, sees rising demand from tracked crushers. Said MironThoms, "We foresee rising demand of tracked crushing plants in India owing to their higher levels of mobility, low operating costs and faster set up times, making them suitable for road contractors requiring crushed granular sub base materials close to construction sites. The rising demand is likely to catalyze demand of our engines."

He informed that there are three demand segments of engines for the mineral processing industry. They include solutions featuring diesel electric drive, direct diesel drive line and diesel hydraulic driveline. "Demand for diesel electric driveline solutions has been flat for us over the years due to better availability of power from local electricity grids; while demand for direct diesel drive solutions has been moderate. However, demand for diesel hydraulic driveline has been robust."

He added: "To ensure more efficient performance of the diesel hydraulic driveline, our application team is working in close association with the OEMs to minimize total cost of ownership, and improvisations are being considered for installation flexibility, ease of maintenance and higher uptime of the engines through extended interval schedules."

As a standard Volvo Penta engines share a number of high-technology design features like compact design and high power to weight ratio, electronically controlled engine control system and waste-gate turbocharger for increased block load acceptance, excellent performance with peak torque at low engine speed. These features contribute to optimized total cost of operations. Also the most of operators will confirm, the high reliability, less down time and excellent fuel efficiency as key benefits of our engines
