Technical characteristics of the engine listed in standard conditions at the inlet of the engine:-atmospheric pressure: 99 kPa (29.31 inches Hg) barometer dry

-air temperature: 25° c (77° f).

Performance is measured using the standard fuel density of 35° on ANI, with a lower calorific value 42.780 kJ/kg (18.390 BTU/lb), at a temperature of 29° c (84.2° f) and the density of 838.9 g/l.

* Mode of IND-A (continuous operation)-continuous mode heavy duty engine when the engine is operated at maximum power and maximum speed up to 100% of the time, without interruption or intermittent load reduction.

* * IND-Mode B-mode operation of the engine, where the power and (or) rotational speed periodically reduced in comparison with the maximum value (duration of work at full throttle does not exceed 80% of the total work time)

Treatment IND-c (intermittent mode)-motor operation with periodic increases in power and speed to the maximum value (duration of work at full throttle does not exceed 50% of the total work time)

D-IND-mode operation of the engine, allowing periodic increases up to the maximum value (duration of operation at full load, not exceeding 10% of the total work time)

IND-E mode-this mode is used when maximum power is required for a short period of time to start or when sudden overload. For emergency operating mode in which the normal power level is not sufficient (duration of work at full throttle does not exceed 5% of the total work time)
