Automotive engines of vehicles having GVW more than 3.5 tons are normally tested on engine dynamometer and therefore can be approved separately for the engine emission and power. For vehicles in the range of 2.5 ton to 3.5 ton may also opt to do the emission test of the diesel engines on engine dynamometer.

Refer attached application forms which could be downloaded and could be used for submission of Technical Specifications for Type Approval at ARAI.
