at engine crankshaft
The engine should be capable of accepting a sudden load as per the guidelines in ISO-8528-5-1993(e). As per this standard, the maximum sudden load increase stages are

               Baseload %     sudden load   increase to %
--------------------------------------------------------------------------------
1st Stage       0%          40                40%
2nd Stage       40%         30              70%
3rd Stage       70%         20              90%
4th Stage       90%         10              100%
--------------------------------------------------------------------------------
During each of the above-mentioned stages of sudden loading, the transient speed drop will be restricted to a maximum value of 10% of the rated speed.

Gas protection system
The DG set is equipped with gas leakage alarm monitoring equipment, which respectively monitors the gas stock in the fresh air inlet main pipe, the gas proportion in the exhaust position of the crankcase breathing apparatus, and the concentration of combustible gas in the main building. When the gas concentration exceeds the set value, the dual-fuel system will quit operation.
When the exhaust temperature is too high, the dual fuel system will automatically and quickly switch to diesel operation mode
When the DG set fault, the gas quick break valve will close automatically
High/Low gas pressure alarm
