French engineer, Rudolf Diesel, first set up shop on the streets of Paris in 1885 with the intention of manufacturing the world’s first compression ignition engine. Rudolf, some 13 years later, accomplished his mission, and industries were introduced to a new and unique power source known as the Diesel Engine. Over a century later and with many modifications and improvements made, we continue to rely heavily upon the diesel engine in the 21st century. The diesel industry as of 2021 is worth a massive $212.4 Billion USD and represents 25% of all types of oil produced and sold.
In the following article we shall cover some of the basics regarding how a diesel engine functions, its purpose, some of Surplus Record’s recommended tips and tricks to assist with the purchasing process of used/new diesel engines for sale, and notes that a buyer should be aware of when on the lookout for used diesel engines for sale.
What is a Diesel Engine?
A Diesel Engine is a type of engine that utilizes compression ignition to turn the energy found in diesel fuel (oil) into rotary mechanical energy. When compared to the equally recognizable Petrol Engine, the way that it functions is similar, being that internal combustion is what produces the mechanical energy. However, the way that a diesel engine functions is much simpler in fact.

- New Diesel Engines for sale
- Remanufactured Diesel Engines for sale
- Engine Assembly for Sale
- Industrial Diesel Engines for sale
- Diesel Engine cores for sale (the diesel engine core is the heart of the engine which usually contains the compressor, burner, and turbine. Diesel core engines for sale are better suited for the sourcing of parts, remanufacturing engines completely, or purchased as old-complete engines.)

How does the Diesel Engine function?
Firstly, air enters a cylinder chamber through an intake valve (see image one above) which then moves the piston downwards. The piston then returns to its original position (upwards) once more and compresses the air to such a degree that temperatures rise. At a calculated moment, diesel is injected into this hot bubble of compressed air which ignites and forces this same piston downwards once more. When this process is repeated, the piston turns the crankshaft component of the engine, thus, generating mechanical power and energy.
Uses and Applications
As mentioned, diesel engines are highly utilized in today’s modern market, and they prove to be extremely practical for use throughout a variety of different industries. These industries include: Nuclear, Food, Agriculture, Hospitality, Chemical, Medical, Paper, Pulp and Plastic Processing, just to name a few. Throughout these varying industries, the diesel engine has differing applications, the most common being powering of automobiles such as tractors, trucks, heavy construction machinery and cars.
Important Considerations Before Buying Diesel Engines
Inspect the Oil
One of the most important steps to consider when viewing a used diesel engine for sale is the condition of the engine’s oil. Start by removing the dipstick (or ask the owner to send you a video/picture) to view the color and appearance of the oil. If there is white coloring in the oil or milky characteristics about the oil’s appearance, it can mean that there are internal problems with the engine, and it may need replacement.
No Servicing = Wear and tear
A diesel engine should be serviced every 6 months at minimum or if functioning within an automobile every three thousand miles. When the correct servicing is not conducted regularly and the engine is left unoperated for long periods/continued to be operated regularly, this can significantly increase the probability of wear and tear and engine inefficiencies. A seller should always be able to provide the buyer with a service history of the engine, completed by professionally trained mechanics.
Size of the Engine (Horsepower)
Whether inspecting a used diesel engine for sale or a new diesel engine for sale it is important to consider the size of the engine you need. Diesel engines can be categorized into small, medium and large in terms of power, which have power outputs ranging from an average low of 50 horsepower to an average high of 1800 horsepower or more. By understanding your personal requirements, it can be easier to select the ideal engine and avoid choosing one that is over or undersized. On Surplus Record, we have available engines ranging in horsepower output from 10 – 2500 HP+.
Age doesn’t necessarily mean unreliability, especially if produced by a reputable manufacturer and serviced regularly. A reputable manufacturer is also likely to have produced a wider range of spare components and parts which makes sourcing these parts easier when the time comes. If the engine is over 10 years in age, it is advisable to inspect the manufacturer’s name and request to view a service history to ensure a successful purchase.
With a variety of accessories available in today’s market for engines, it can be ideal to purchase a used or new engine with such extras. Cooling fans can be a desirable accessory for diesel engines for those who desire improved fuel economy and reduction in noise, as well as more efficient performance. Purchasing these fans or an engine which has a fan included is highly recommended by the Surplus team.
