Emissions Test Procedure Clause Samples

Emissions Test Procedure. 6.1. Test cycle The operating cycle, made up of a Part One (urban cycle) and Part Two (extra-urban cycle), is illustrated in Figure A4a/1. During the complete test the elementary urban cycle is run four times followed, by Part Two. 6.1.1. Elementary urban cycle Part One of the test cycle comprises 4 times the elementary urban cycle which is defined in Table A4a/1, illustrated in Figure A4a/2, and summarized below.

Extra-urban cycle Part Two of the test cycle is the extra-urban cycle which is defined in Table A4a/2, illustrated in Figure A4a/3, and summarized below. Breakdown by phases: Time (s) per cent Idling 20 5.0 Deceleration, clutch disengaged 20 5.0 Gear-shift 6 1.5 Accelerations 103 25.8 Steady-speed periods 209 52.2 Decelerations 42 10.5 Total 400 100 Breakdown by use of gears: Time (s) per cent Idling 20 5.0 Deceleration, clutch disengaged 20 5.0 Gear-shift 6 1.5 First gear 5 1.3 Second gear 9 2.2 Third gear 8 2 Fourth gear 99 24.8 Fifth gear 233 58.2 Total 400 100 General information: Average speed during test: 62.6 km/h Effective running time: 400 s Theoretical distance covered per cycle: 6.955 km Maximum speed: 120 km/h Maximum acceleration: 0.833 m/s2 Maximum deceleration: -1.389 m/s2 6.1.3. Use of the gearbox 6.1.3.1. If the maximum speed which can be attained in first gear is below 15 km/h, the second, third and fourth gears shall be used for the urban cycle (Part One) and the second, third, fourth and fifth gears for the extra-urban cycle (Part Two). The second, third and fourth gears may also be used for the urban cycle (Part One) and the second, third, fourth and fifth gears for the extra- urban cycle (Part Two) when the manufacturer's instructions recommend starting in second gear on level ground, or when first gear is therein defined as a gear reserved for cross-country driving, crawling or towing. Vehicles which do not attain the acceleration and maximum spe...
