Bibliography

Defines the emission measurements for a thermal electric hybrid road vehicle from M[1], N[1], or M[2] category, and for tricycles and quadricycles from the motorcycle types. Applicable to above mentioned vehicles whose emission can be tested following the provisions already laid down for conventional vehicles (i.e. Internal Combustion engine vehicle) from the equivalent categories.
