What is an engine?
An engine is also known as a motor. An engine may be referred to as a machine which is designed to convert one form of energy into mechanical energy. An engine burns up the fuel (a form of energy) to create heat, which in turn will create a force. This force will facilitate the movement of a particular machine.

What is a diesel engine and how does it work?
An engine that uses diesel as a fuel or form of energy and converts it into a force is known as a diesel engine. It uses diesel as the combustion fuel. A diesel engine is an engine that uses compression ignition. Diesel is a heavy fuel, thus, many refer to a diesel engine as a heavy fuel engine. Some other engines use spark ignition but diesel engine does not use spark ignition to get itself started.
Rudolf Diesel was the creator of the original diesel engine which he created in the year 1892. However, the engine he constructed used a higher compression than what is actually needed for compression ignition. The idea of diesel is to compress the pure atmospheric air so tightly in order to increase its temperature and initiate combustion. In the year 1895, a patent was granted by the United States to Diesel.
It is an internal combustion engine. The gas is injected to the combustion chamber. Combustion is achieved when the gas achieves high temperature. The gas will achieve high temperature only when it is greatly compressed. Diesel engines work by compressing the air unlike the spark ignition engine used in petrol engines. In spark ignition, the air and fuel mixture together is compressed. At the specified time the spark plug ignites the air and fuel mixture.
The original diesel engines do not create an audible knock and there is a cycle of gradual combustion at the start up. In cold months, it might take a little longer to get a diesel engine started, as the air compression temperature at the beginning is not very high.

| Diesel Engine Reconditioned |
How and why to get a diesel engine reconditioned?
As we already know by now, a diesel engine is an internal ignition engine, which uses heat to ignite the fuel. We should also know that it is the engine having highest thermal efficiency. No regular engine can beat it when it comes to its thermal efficiency. But it has this thermal efficiency because of its high compression ratio. A diesel engine reconditioning may be required within 10-20 years. The service life of such engine is usually 7-10 years. Thereafter, such diesel engine will require rebuilding or reconditioning.
This diesel engine reconditioning has to be done from time to time to keep the engine working and in good condition. Though, diesel engines are usually heavily built ones, they too require reconditioning from time to time. Reconditioning is a better and much cheaper option than replacing it. It is best if such reconditioning is left at the hand of a professional who has sound understanding of the technicalities of an engine and more. Nevertheless, it can be done by a person by following certain steps in an order:
Firstly, there are certain tools that have to be purchased for diesel engine reconditioning. The basic tools which are required for reconditioning are a piece of cloth, wrench, hand tools, ring compressor, gauge and ring expanders, etc. One has to check the cylinders for wear and tear. Consider seat re-facing equipment and an engine rebuilding kit as a requirement to own with your engine. Even though it might seem easy to do, but diesel engine reconditioning is a complicated process.
