What Are the Common Differences Between Marine and Industrial Diesel Engines?

Capable of sparking life to a broad spectrum of equipment, engines and their accumulating list of types have grown to convert many sources of energy into harnessed power. Ranging from physical engines and electrical engines, to thermal engines and their use of diesel or non-diesel fuel, modern applications of these units now serve to power many facets of human society. Specifically, when analyzing diesel-fuelled internal combustion engines, a subclassification of thermal engines, the parts that comprise these powerhouses are unique in their own accord. Depending on whether a diesel engine will be used for industrial or marine applications, this information will further diversify what parts make up these units. Within this blog, to better understand the basics behind diesel engine types, we will discuss the primary differences between industrial and marine diesel engines.

Marine diesel engines, unlike their counterpart, are composed of sophisticated exhaust, cooling, electrical, and fuel systems. Built to withstand cruising the open ocean, the heavy duty parts making up this classification of engines are capable of withstanding ten to fifteen-thousand hours of operation before an engine overhaul should be considered. Although similar in core design to any typical diesel engine, the engines used for marine applications are prone to corrosion and lack of lubrication if left idle. Needing areas of internal spot welding to provide additional structural support for connecting engine parts, without consistent maintenance, marine engines would be incapable of meeting their life expectancy. Beside the need for frequent mitigation of corrosion brought on by salt, water, and humidity, the construction of a marine engine starter, alternator, distributors, carburetor, fuel pump, and water pump are commonly made of water-resistant materials to alleviate some of the aforementioned issues.

In comparison, while industrial diesel engines can be adapted to work for marine craft if need be, they are better suited for dry settings and areas of which marine classifications are deficient in. Often qualified to perform for five hundred thousand to one million miles before an overhaul is needed, industrial engines are not as predisposed to as many environmental factors as compared to marine engines.

The end goal of any engine is to produce a source of forward momentum capable of driving a vehicle. While providing the accurate amount of power necessary to move, based on their types and what fuels they use to function, engines require routine maintenance and inspection to prolong the use of internalized equipment.
