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.
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 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
With our readiness and extensive global experience in BS CEV IV equivalent products we are confident on our ambitious growth plans in coming years.
