Industrial diesel engines are any engines that are used

for industrial purposes that run on diesel. Industrial

diesel engines are used to power a major portion of

industrial machinery, from motorbikes to bulldozers,

generators, and even forklifts and trucks. They range

in size from a few pounds to a few tons, with a various

amount of power.

The use of diesel engines is mandated by several large

organizations. All NATO machinery for example, runs on

either diesel or aviation grade kerosene. At the

current level of technology, fossil fuels, and especially

diesel are the most economical and convenient means

of supplying power to a variety of equipment and

even backup generators.

All industrial diesel engines can be either air cooled

or water cooled. The smallest engines for residential

purposes will typically provide about 10kW and cost

a few thousand USD. These smaller scale engines power

much of the mobile machinery we see around us on a

daily basis, such as trucks, farm equipment, small

boats, stationary process machinery, earth movers,

and so on.

The medium scale industrial diesel engines can provide

levels between a few hundred kW and a few thousand

kW and are sold for prices in usually the thousands

of dollars. These types are used in larger machinery

such as larger mining equipment, oil rigs, trains,

large boats, military equipment, and much more.

The largest of industrial diesel engines provide 10,000

to 80,000 kW, sold in the millions of dollars, and

are used for ultra heavy equipment, electric power

generation, and the largest of ships. Large industrial

engines can be up to 49 feet side and run on low

grade diesels. In places such as China, where there

is a high demand for de-centralized power sources,

these types of engines are often utilized.

Industral engines are classified in terms of their

speed, or RPM (Rotations Per Minute). High RPM

engines are normally used for the lighter, more common

applications, such as trucks and other types of land


Medium RPM engines are generally used for power

generation. Low RPM ranges, and high torque engines

are used for the biggest type of equipment, such as

marine equipment and applications.

For the most part, industrial diesel engines can

vary in terms of size and performance. Chances are,

you’ve either seen or used industrial equipment at

some point in time. Although they cost a lot of

money, they are the way to go with bigger equipment

for getting the job done right the first time.
