Q3: Can Weichai produce 60Hz marine generator sets?

A: Yes. Weichai's product spectrum and introduction are mainly based on 50Hz products, but 60Hz products of corresponding power can also be produced.

Q4: How is the "prime power" of Weichai marine generator sets defined?

A: The definition of prime power is as follows:

*The average load rate over 24 hours of running does not exceed 70%;

*Within every 12 hours, the engine can run for 1 hour with a 10% overload;

*The annual running time is unlimited.

Q5: How is the "continuous power" of Weichai marine generator sets defined?

A: The definition of continuous power is as follows:

*Allows operation at a constant 100% load;

*Within every 12 hours, can run for 1 hour with a 10% overload;

*The annual running time is unlimited.

Q6: How to select power matching according to ship type?

A: Power matching requirements are as follows:

*Ocean-going fishing vessels: Annual running time exceeds 3000 hours, should be matched or selected according to continuous power;

*Inland transport ships, coastal fishing vessels, high-speed boats: With living electricity or auxiliary pumps as the main load, can be matched or selected according to prime power;

*Light lure fishing vessels, rake fishing vessels, floating crane vessels, sand suction vessels, and lifting engineering vessels: It is recommended to coordinate with the application department before selection.

Q7: Which series have the same prime power and continuous power values?

A: The CW200 series, CW250 series, WH620 series, WH20 series, WH25 series, and WH28 series have the same prime power and continuous power values. The high-speed engine series, WHM6160 series, 170 series, and WH17 series are divided into prime power and continuous power.

Q8: What are the environmental requirements for installing Weichai marine generator sets?

A: Installation requirements are as follows:

1. The installation site must be well-ventilated. The generator end should have sufficient air inlets, and the diesel engine end should have good air outlets. The outlet area should be more than 1.5 times the radiator area;

2. The surroundings of the installation site should be kept clean, and items that can produce corrosive gases and vapors such as acids and alkalis should not be placed nearby.

Q9: What are the precautions after starting Weichai marine generator sets?

A: After starting, wait until the oil pressure reaches the requirement before gradually increasing the speed. When the water temperature is below 70℃, full-speed operation is not recommended. When the oil outlet temperature exceeds 45℃, pay attention to the oil pressure.

Q10: How often should Weichai marine generator sets be serviced?

A: It is recommended to service at least once a year or after every 100 hours of operation. Regular maintenance includes checking oil levels, fuel system, battery, air filter, cooling system, and electrical connections.

Q11: What does daily inspection of Weichai marine generator sets include?

A: Daily inspection should include:

1. Check the engine oil level;

2. Check the engine coolant level;

3. Check the water pump belt;

4. Check the marine gearbox;

5. Check the engine for leaks, damage, or looseness.

Q12: What should be paid attention to during maintenance of Weichai marine generator sets?

A: During maintenance, pay attention to the working environment: there should be no accumulation of water, oil, or waste around, and no corrosive gases, to prevent damage to the generator winding insulation.

Q13: What causes cylinder misfiring in generator sets?

A: Common causes of cylinder misfiring include:

1. Clogged injector nozzles, preventing fuel injection into the cylinder;

2. Mechanical failures such as broken piston rings, cylinder scoring, or poor valve sealing, causing insufficient cylinder pressure;

3. Fuel pump plunger or delivery valve faults, resulting in insufficient or no fuel supply to the cylinder;

4. Starting in winter or low temperatures, some cylinders may temporarily not run after cold start and gradually return to normal as temperature rises.

Q14: What are the hazards of cylinder misfiring in generator sets?

A: Cylinder misfiring causes unstable operation and unbalanced stress on the unit, leading to excessive vibration and deformation of the body, seriously affecting the service life of other components. Once cylinder misfiring is detected, stop operation immediately and wait for professional inspection and troubleshooting.

Q15: What are the effects of excessive fuel supply advance angle?

A: Excessive fuel supply advance angle can cause the following problems:

1. Excessive fuel combustion increases piston top heat load, causing piston overheating damage;

2. Excessive heat load causes cylinder head cracks and valve seat ring deformation and detachment;

3. Increased cylinder liner vibration accelerates cavitation erosion;

4. Causes knocking, increasing piston impact force on the cylinder liner;

5. Excessive explosion pressure increases the mechanical load on piston connecting rods;

6. High explosion pressure allows high-temperature gas to enter the lower crankcase, causing oil high-temperature cracking and potential crankcase fire.

Q16: What classification society certificates can Weichai marine generator sets provide?

A: Weichai marine generator sets can provide CCS (China Classification Society), ABS (American Bureau of Shipping), BV (Bureau Veritas), DNV (Det Norske Veritas) and other classification society certificates. Units with power range of 16kW-100kW can provide CCS certificates.

Q17: What are the emission standards for Weichai marine generator sets?

A: Weichai marine generator sets can meet IMO II (International Maritime Organization Tier II) emission standards. Some products can meet China Phase I emission requirements.

Q18: What types of vessels are Weichai marine generator sets mainly used on?

A: Weichai marine generator sets are widely used in:

1. Bulk carriers.

2. Engineering vessels.

3. Fishing vessels (including gillnet vessels, purse seine vessels, etc.).

4. Government vessels.

5. Ferries.

6. Yachts.

7. Tugboats.

8. Fire boats.

9. Multi-purpose vessels.

10. Crew boats.

Q19: What are the advantages of Weichai marine generator sets?

A: Advantages of Weichai marine generator sets include:

1. High thermal efficiency and low fuel consumption rate. Some units have thermal efficiency up to 45% and fuel consumption rate of 190g/kWh or even lower;

2. Low operating costs, can use multiple fuels, low requirements for fuel quality, suitable for burning heavy oil with higher viscosity.
