Mercedes-Benz introduces India’s first BS VI compliant vehicle

The vehicle, a Mercedes-Benz S 350 d has undergone stringent emission test related to BS VI emission at ARAI, Pune and has been certified as BS VI compliant. Following are some of the tests done at ARAI for the certification of the BS VI engines:

1-Tail pipe emission test in laboratory – limits lowered to 68 to 82% as against BS-IV

2-Engine power test – BS-VI fuel based test

3-On board diagnostic (OBD) test – Stringent OBD test

4-RDE (Real Driving emission) - On road emission performance test

The new six-cylinder Diesel engine is designed to comply with future emissions legislation (RDE – Real Driving Emissions). All the components of relevance for efficient emissions reduction are installed directly on the engine. The integrated technology approach combining the new stepped-bowl combustion process, dynamic multi-way exhaust-gas recirculation and near-engine exhaust-gas after treatment, for the first time combined with variable valve-lift control, makes further reduced consumption with low emissions possible.

Although the output has increased noticeably compared to the preceding model, the new engine consumes up to six percent less fuel. The special traits of the top-of-the-line engine in the diesel family include the stepped-bowl combustion process, two-stage turbocharging and, for the first time, the use of CAMTRONIC variable valve-lift control. Its design features a combination of aluminium engine block and steel pistons as well as further improved NANOSLIDE® coating of the cylinder walls.

The Certificate of Compliance to the CMVR (Central Motor Vehicles Rule) for Mercedes-Benz India was presented by ARAI Director, Rashmi Urdhwareshe to Roland Folger, MD & CEO, in the presence of Nitin Gadkari i, Minister of Road Transport Highways & Shipping and Water Resource, River Development, & Ganga Rejuvenation and Abhay Damle Ji, Joint Secretary, Ministry of Road Transport Highways and other dignitaries.
