▼ Four-stroke inboard marine generator runs quieter. They are also easier to maintain and more environmentally friendly in terms of emissions.They are more suitable for small and medium-sized ships. They are also a good choice for scenarios that have requirements for low noise and environmental protection.Diesel engines do not rely on batteries or external charging. They can work independently in the open sea where there is no power grid coverage.Refueling (adding diesel) is convenient. These engines do not need to "charge for a long time" like electric motors.So diesel engines are suitable for long-distance navigation or emergency operation scenarios.

- A Inboard Marine generator is the "power heart" of a ship.All electrical devices on the ship rely on it for power.For example, the radar and navigation equipment on the bridge, as well as the lighting, air conditioners and refrigerators in the cabins.Besides, the cranes for loading and unloading goods, communication devices, and even the auxiliary control system of the main engine all need electricity generated by it.If the generator stops working, the ship may lose the ability to navigate and communicate.Even the basic electricity for daily life on the ship will be cut off.So it is the "power guarantee" for the ship's navigation and operations.
The marine environment is harsher than the land environment. So marine generators have special designs.
1.Anti-salt spray design
The outer shell and internal parts are all treated for rust and corrosion resistance.For example, they are coated with anti-salt spray paint. This prevents the machine from rusting.
2.Anti-sway design
There are fixed brackets at the bottom of the machine. The internal parts are also reinforced.Even if the ship shakes violently at sea, the generator can still run stably. It won't drop parts or stop working.
3.Adaptation to high temperature and high humidity
Marine generators are equipped with special cooling fans and dehumidifiers.In summer, the sea has high temperature and high humidity. But these devices can ensure the generator doesn't "overheat" or "get damp".
Inboard Marine generator has stable performance. They can work for a long time and won't break down frequently.After all, maintenance at sea is not easy, so stability is the most important thing.Marine generators don't need separate special fuel. Most of them can use the same type of diesel as the ship's main engine.
There's no need to store "main engine oil" and "generator oil" separately on the ship. This not only saves oil storage space but also reduces the steps for refueling.Their emissions can meet the environmental standards of the International Maritime Organization (IMO). They won't be fined by ports for "exceeding emission limits".Moreover, they have overload protection. If there are too many electrical devices and the current is too high, they will automatically cut off the power. This protects the machine and the ship's electrical circuits.
