IND – A mode (continuous operation) – the mode of continuous operation of the engine in severe conditions, when the engine is operated at maximum power and maximum speed up to 100% of the working time, without interruption or periodic load reduction.
IND – B mode – engine operation mode, in which the power and (or) rotation speed periodically decrease in comparison with the maximum value (the duration of operation at full load does not exceed 80% of the total operating time)
IND mode – C (intermittent mode) – operation of the engine with a periodic increase in power and (or) speed to maximum values (duration of operation at full load does not exceed 50% of the total operating time)
IND – D mode – engine operation mode, in which periodic increase in power to the maximum value is allowed (duration of operation at full load does not exceed 10% of the total operation time)
IND – E mode is a mode in which maximum power is required for a short period of time for starting or in the event of a sudden overload. For emergency operation where the normal power level is not sufficient (run time at full load does not exceed 5% of the total run time).
