Marine engines are also regarded as IC engines just like other conventional engines.
But some features make the marine engine different.
1. The size: Marine engines are usually big, they are referred to as heavy-duty engines. You should know that most car engines are not regarded as a heavy-duty engines. This means bigger tools are needed to carry out repairs on marine engines. ProDieselParts offers the parts necessary to repair your marine engines.
2. The exhaust system: There is a difference between how the marine exhaust system works. Due to long hours of work, the exhaust system will become extremely hot so there is a need for a cooling system for the exhaust system. That is why marine exhaust is called a wet exhaust system. This means water from the sea is allowed to pass through the exhaust system to provide a cooling system. Non-marine engines do not have a wet exhaust system.
3. Low rpm engine: Marine engines are known for low rpm. When it comes to rpm, marine engines run at a lower rpm compared to non-marine engines. The reason for this is that marine engines run for days without stopping. Imagine an engine that runs for 5000 hours continuously without stopping. So such an engine cannot be running on higher rpm for that long hours.
4. Ability to withstand load for a long period: Do you know that as soon as the ship starts moving, the engine is on load. So a marine engine is constantly on load due to water resistance. So the engine must be strong to cope with constant load. Compared to other non-marine engine, truck’s engine is not constantly on load because it doesn’t have the same water resistance.
5. Differences in some components: There are some similarities between the components of marine and non-marine engines. For example the Kickstarter. In most marine engines, what causes sparkling is totally avoidable. So in such circumstances instead of an electrical Kickstarter marine engine uses a pneumatic or hydraulic Kickstarter to start the engine to prevent an electric spark. Another area is that the materials used for marine engines are corrosion-resistant materials. It is because the engine is working around water, so as not to corrode quickly, the marine engine components are made of material that can resist corrosion.
