119 Exhaust emissions – diesel-powered light vehicles

(1)  In this regulation –

oxides emission rate means the rate measured in grams of oxides of nitrogen emitted per kilometre travelled by a light vehicle per tonne of the test mass of that light vehicle;

particle emissions rate means the rate measured in grams of particles emitted per kilometre travelled by a light vehicle per tonne of the test mass of that light vehicle;

tare mass, of a vehicle, means the unladen mass of the vehicle, however described;

test mass of a vehicle, means –

(a) if the vehicle is a light prime mover, half the sum of its tare mass and its GCM; or

(b) for any other light motor vehicle, half the sum of its tare mass and its GVM.

| Note: | The purpose of a test mass in relation to a vehicle is to apply a load to the dynamometer, while the vehicle is under test, to simulate half payload operation. |

(2)  This regulation applies to a light motor vehicle that –

(a) is powered by a diesel engine; and

(b) meets the criteria for a passenger vehicle, including omnibuses and goods vehicles, as defined under the ADRs.

(3)  When a vehicle is tested in accordance with regulation 121 , the vehicle must comply with the following requirements:

(a) the vehicle must not emit oxides of nitrogen at an oxides emission rate greater than that stated for the vehicle according to its GVM rating and age in the following table:

| Item | GVM rating of vehicle | Oxides emission rate (g/km/t) |

| | | Vehicle manufactured in December 1995 or earlier | Vehicle manufactured in January 1996 or later | | 1. | 3.5 or less | 1.5 | 1.5 | | 2. | More than 3.5 | 2.0 | 2.0 |

(b) the vehicle must not emit particles at a particle emissions rate greater than that stated for the vehicle according to its GVM rating and age in the following table:
