230 THE CENTRAL MOTOR VEHICLES RULES, 1989 RULE 115A
1
[(9) Every agricultural tractor, power tiller 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, namely:—
(a) for variable-speed engines, the 8-mode test cycle or the corresponding
ramped modal cycle and the transient cycle 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 applicable emission limit for
2
[Non-Road Steady Cycle (NRSC)] and Non-Road Transient Cycle (NRTC)
test cycle as per test applicability mentioned in Table 1 and Table 2 given
below and 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 given
in said tables.
