Two pollution tests must for vehicles with flex fuel option
All bi-fuel vehicles with flex fuel option will have to undergo tests for both gaseous pollutants as well as particulate mass and number when seeking vehicle type approval under BS VI emission norms. However, hydrogen-run vehicles will have to undergo tests only for emissions of nitrogen oxide, the ministry of road transport and highways said in a notification on applicability of test requirements for type approvals.
