Cummins Engine Warranty Items for Diesel Generator Part 1

Aug. 18, 2021

The engine quality assurance regulations of Cummins diesel generator sets refer to the engine warranty regulations of Cummins International Drive Generator, document number 3381307-10/04. Cummins engine warranty clauses apply to new engines sold by Chongqing Cummins Engine Co., Ltd. and used for power generation in mainland China. The Cummins engine is provided by Chongqing Cummins contract maintenance service and sold to Cummins engines outside of mainland China. These Cummins engines have the following power characteristics:

 

1. The spare power of Cummins diesel generator set.

 

The spare power of Cummins diesel generator set is used to provide emergency power when the utility power is interrupted. The rated Cummins engine cannot reach the overload capacity. The engine is not allowed to run in parallel with the utility power supply at the standby power under any circumstances. This type of power supply is used where reliable public power is available. The backup-powered engine runs up to 80% of the average load factor, and runs no more than 200 hours per year. This includes operating on standby power for no more than 25 hours per year. If it is not an emergency of a real power failure, the standby rated power should not be used. Negotiable blackouts stipulated in the contract of the public power company shall not be regarded as an emergency.

2. Cummins ordinary power does not limit the running time.

 

Cummins engines of this power are used in variable load occasions with unlimited hours per year. During 250 hours of operation, the variable load should not exceed 70% of the average power normally used. If it is operated at 100% normal power, its total operating time should not exceed 500 hours. It can reach a load capacity of more than 10% when running for 12 hours. The total operating time is more than 10%, and the annual operating time must not exceed 25 hours.

 

3. Commonly used power limits the running time.

 

Cummins engines of this power are used to limit the number of hours of constant load usage. It is used in the event of a power outage according to the contract. For example: the power utility company cancels power supply. Cummins engines can be operated in parallel with public electricity for no more than 750 hours per year, but their power level cannot exceed the usual power. The power used to limit the operating time and the power that does not limit the operating time is because: even if the maximum output power of the engine is the same, the engine with limited operating time can be connected in parallel with the utility power and run at full load at the usual power, but it must not be exceeded Regular power.

 

4. Continuous/basic power.


The power supply is used to supply public electricity, and there is no limit to the number of working hours per year, and it operates stably at 100% load. The power plant cannot reach the capacity of overload operation. The continuous/basic power is not limited to the normal operating time compared to the normal power, the continuous/basic power is much lower than the normal power. There are no load factors or application restrictions for continuous/basic power.
