Common Problems Found in Marine Diesel Engines

A marine diesel engine is the core component of any kind of marine Marine Diesel Enginesvessel. It provides the propulsion power required to push the ship forward. These kinds of engines are very sturdy and durable. They are heavy duty machines that can last for decades if they are properly maintained.

In order to ensure that your marine diesel engine runs smoothly, it is necessary to maintain it properly. A professional marine engine maintenance services will be able to keep your ship’s engine in good shape. They will also be able to identify potential problems beforehand and suggest appropriate measures to fix them.

When replacing the old, worn out parts of marine diesel engines, it is necessary to use the best quality spares available in the market.

Always remember to buy your spares from an experienced supplier that has the necessary expertise to ensure that they are installed and maintained properly.

What are the problems that marine diesel engines frequently encounter?

Even the finest quality machines tend to break down every now and then. A ship’s engine has to endure tough operating conditions and is often used for lengthy periods. Every once in a while, your ship’s engine is bound to come across some kind of technical problem that will adversely affect its performance.

Since the 2-stroke engines used in most ships are complex pieces of machines, they must be handled with care and regularly monitored to check for signs of wear and tear.

Here is a list of some of the problems that are commonly faced by marine diesel engines:

Fuel leakages

The fuel system in a marine diesel engine is quite intricate. Extreme temperature variations can often be harmful for the fuel system and can cause fuel pipes to develop leaks.

If a leakage develops, due to rusty pipes or malfunctioning valves, the fuel pressure in the engine decreases. This negatively impacts the performance of the engine and its output power also decreases

It is also worth mentioning here that the pump seals can also develop leakages at times. Therefore, the seals must also be regularly checked for leakages and promptly replaced if they are worn out.

Sparks in the exhaust funnel

Sometimes sparks can also be seen to be coming out of the main engine’s exhaust funnel. This problem usually occurs due to excessive maneuvering of the ship or using the slow steaming propulsion mode.

The accumulation of soot deposits, produced by the activities mentioned above, in the exhaust gas boiler is the main causes behind the sparking problem. In order to solve this problem, the exhaust boiler has to be cleaned by an expert diesel engine maintenance technician.

Faulty cooling systems

If the ship’s engine cooling systems are not working properly, the engine will overheat. This is a serious problem because it can cause grave damage to the engine.

Faulty cooling systems

Blockages in the water inlets or intake pumps are the common reasons for the malfunctioning of a marine engine’s cooling systems. If you notice a rise in your marine engine’s core temperature, be sure to check the cooling systems for blockages.

Malfunctioning sensors

Malfunctioning marine engine sensors can often give false alarms or fail to detect genuine problems with the engine. The engine’s sensor can break down due to high temperature conditions, elevated humidity level, or the presence of excessive dust particulates.

If the sensors fail to detect a problem with the main engine’s performance, it could have catastrophic consequences for the engine itself. Therefore, it is necessary to get your ship’s sensor inspected on a routine basis to ensure that they are in good working condition.
