- AES
means an emission strategy that becomes active and replaces or modifies a BES for a specific purpose and in response to a specific set of ambient or operating conditions and only remains operational as long as those conditions exist.
- BES
means an emission strategy that is active throughout the speed and load operating range of the vehicle unless an Auxiliary Emission Strategy is activated;
- bi fuel gas vehicle
means a bi fuel vehicle where the two fuels are petrol (petrol mode) and either LPG, NG/biomethane, or hydrogen;
- bi fuel vehicle
means a vehicle with two separate fuel storage systems that is designed to run primarily on only one fuel at a time, however, the simultaneous use of both fuels is permitted in limited amount and duration;
- deficiency
means, in the context of the OBD system, that up to two separate components or systems which are monitored contain temporary or permanent operating characteristics that impair the otherwise efficient OBD monitoring of those components or systems or do not meet all of the other detailed requirements for OBD;
- flex fuel ethanol vehicle
means a flex fuel vehicle that can run on petrol or a mixture of petrol and ethanol up to an 85 per cent ethanol blend (E85);

- MI
means a visible or audible indicator that clearly informs the driver of the vehicle in the event of a malfunction of any emission-related component connected to the OBD system, or of the OBD system itself;
- mono fuel gas vehicle

- mono fuel vehicle
means a vehicle that is designed to run primarily on one type of fuel;
- net power
means the power obtained on a test bench at the end of the crankshaft or its equivalent at the corresponding engine or motor speed with the auxiliaries, tested in accordance with Annex XX, and determined under reference atmospheric conditions;
