Notification regarding emission standards for construction equipment vehicles, and agricultural tractors
The Road Transport Highways Ministry has issued a draft notification regarding emission standards for construction equipment vehicles, and agricultural tractors on 29 August, 2017. Every diesel driven agricultural tractor and construction equipment vehicle and combine harvester shall be so manufactured that it complies with the following standards of gaseous pollutants emitted by them when tested on following duty cycle: (a) For variable-speed engines, the 8-mode test cycle or the corresponding ramped modal cycle, and the Non Road Transient Cycle (NRTC). (b) For constant-speed engines, the 5-mode test cycle or the corresponding ramped modal cycle. (c) Emissions (g/kWh) shall be measured over Non Road Steady Cycle (NRSC) and Non Road Transient Cycle (NRTC) test cycle as per test applicability mentioned in Table 1 and Table 2. For NRTC test cycle, composite weighted emissions shall be computed by weighing the cold start results 10 per cent and the hot start results 90 per cent. Weighted composite results shall meet the limits.
