Tata Motors has received BS6 Type Approval certificate for its 3.8L NA SGI CNG engine from ARAI (Automotive Research Association of India), the company said. With this it has become the first OEM in India to achieve BS6 certification for a ‘naturally aspirated’ CNG engine for commercial vehicles, it added. This certification includes meeting the tailpipe mass emissions as well as compliance with on-board diagnostics norms as mandated by government regulation. With this success, Tata Motors continues to stay on its path of offering environment friendly products in India, it said.
The 3.8 NA SGI CNG engine is a ‘naturally aspirated’ engine as it does not need a turbocharger. It produces a maximum power of 85 Ps @ 2500 RPM with a torque of 285 Nm @ 2500 RPM. This combustion occurs at stoichiometric conditions in this engine.
