A marine diesel engine consists of many working parts. Even though different components can make a few modifications to their designs, their functions remain the same. Each component has a specific function and location to make it work. Chances are, you already know a little something about marine diesel engines. Even if you do, our Marine Diesel Specialists want to ensure you know all the ins and outs regarding how these engines function. This is why we are providing the information below.

Marine diesel engines are very similar to self-ignition engines in heavy-duty vehicles. However, these are generally larger and more complex, and they operate with higher efficiency. Diesel engines, apart from having a more reasonable fuel economy than gasoline engines, also have a prolonged life span. Automobile engines can often do their rightful jobs for longer than boat engines. This is because they aren’t exposed to as many woes as marine diesel engines. Problems with diesel engines are usually relatively simple, and with a  little regular preventative maintenance, one can avoid the need for repairs at sea. 

Types of Marine Diesel Engines:

The two basic types of marine diesel engines are:

  • 4 stroke engine
  • 2 stroke engine

A stroke refers to the full travel of the piston along with the cylinder in either direction. A four-stroke engine can be installed on the ship to produce electrical power. It can also propel the ship, though usually only in smaller size vessels. While marine diesel engines may look similar and, indeed, share a number of similar components, the operating cycle of the two-stroke engine is entirely different from that of the four-stroke.

Two-stroke engines are used for vessel propulsion and are bigger in size as compared to four-stroke engines. In this engine, the complete sequence is completed in two cycles. Alternatively, a four-stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning a crankshaft. 

The Reliability of Marine Diesel Engines

When Rudolf Diesel unveiled his engine to the world in 1892, it was nothing short of a revelation. Today we reserve our excitement for batteries and electric power, and the miracle of the combustion cycle has almost been entirely forgotten. Once a degree of reliability is reached, our attention wanes – that is, until something goes wrong. 

Sitting at the heart of even the most advanced hybrid boats is a diesel engine, albeit one driving a generator to produce electricity. Despite the rapid growth of electric technology and clean energy across boating, the marine diesel engine will have a role to play for many years to come as a source of battery charging. 

Marine diesel engines are incredibly reliable. They mainly only require air, fuel, and water. Then add some electrical power for starting, and you have covered the range of needs for a diesel engine. These engines are built very durably to handle the compression force of the ignition cycle. The fuel itself is an oil that gently lubricates the engine as it runs.
