Application of diesel engine in various industries
Different types of diesel engines are used in different industries. In the following, we will introduce their applications:
Application of diesel engine in air industry
In the past, diesel engines were widely used in airplanes, but gradually due to the pressure difference that occurs at high altitudes, the use of these engines was abandoned and nowadays they are not used in the aviation industry. be made But it should be noted that these engines are still used in the aviation industry and in helicopters, so that the most powerful American helicopter, which is capable of carrying 8 thousand tons, uses a 24-cylinder circular diesel engine. has been taken The way of connecting diesel engines in helicopters is that instead of connecting them to the crankshaft and flywheel, they connect them directly to the propeller shaft.
Application in tanks
Another application of diesel engines is their use in tanks, which, due to their power, can move very heavy tanks weighing 2,000 tons at a speed of 60 kilometers per hour.
Application of diesel engine in marine industry
One of the applications of these engines is to generate electricity to drive non-nuclear submarines as well as commercial ships in the maritime industry. These submarine engines are so powerful that they are able to work even at great depths and around 3 thousand kilometers.
Application of diesel engine in transportation industry
Most of these engines are used on roads, cities and on diesel generators. Diesel engines play a very important role in the road transport industry. These engines are not only used in heavy vehicles such as light and heavy trucks, as well as buses and minibuses, but nowadays they are also used in passenger cars in western countries, and the reason for this is that gasoline is expensive. And the high taxes related to it.
Application of diesel engine in agricultural industry
Diesel generators are widely used in tractors, irrigation pumps and threshing machines in agriculture.
Application of diesel engine in electricity industry
It can be said that most of the generators that are used in non-domestic or industrial purposes, diesel engines have been used in them.
Application of diesel engine in domestic use
Diesel engines are used to supply electricity to residential buildings in emergency situations.
Application of diesel engine in urban use
These engines are used to supply electricity to hospitals, offices, organizations and companies when there is a power outage and the possibility of causing damage to them is very high.
Application of diesel engine in information technology
Power outages in some information technology units can cause irreparable damage to internet users. Servers are one of the most important devices that cause a lot of damage in the event of a power outage. For this reason, to prevent them from turning off during power outages, these devices are always connected to a power generator.
Application of diesel engine in food industry
One of the most important and essential needs of food industry units is the operation of refrigerators and freezers to preserve food and prevent it from spoiling. Diesel generators are used to supply electricity to these devices.
Application of diesel engine in industries and mines
Power generator is needed to keep the drill and some other mining equipment on in the extraction of natural resources such as gold, silver or even oil extraction from underground. It is one of the most and most important applications of diesel engines in this sector.
Is it necessary to use diesel engine in hospitals?
Yes, the hospital is one of the places where emergency power supply is very necessary and when accidents happen, it is necessary to use these devices to supply power so that the lives of patients are not endangered.
Application of diesel engine in power plants
One of the most important areas of a country can be considered its power plants. The power plant provides the necessary energy to supply electricity to a city.
However, there are many cases that may cause problems in electricity distribution, in which case emergency power supply becomes important.
With a history of more than 30 years, Dasht Noor Diesel Store has the ability to supply generators needed for power plants. You can contact us for more information.
Is it important to use diesel engine in data centers?
Yes, it definitely is. As you know, nowadays computers are at the heart of the industry and if the servers and systems fail, the communication is generally interrupted and almost All work will stop.
For this purpose, it is necessary for telecommunications and all communication companies and so-called data centers to use the power backup option.
Which type of generator is more practical?
Because diesel generators have much higher power than other types of generators and are also more economical in terms of fuel consumption, it can be said that they are considered the most practical type of generator.
In general, for a better understanding of the reasons for using diesel fuel, the following can be mentioned:
- Less heat generation
- Longer life of the device using this type of fuel
- Having more power than other types of these devices
- Having a lower price than other fuels
The reason why diesel engines are better than gasoline engines
Why diesel engines are considered better than gasoline engines are for the following reasons:
- Cheaper fuel
Diesel engines are more economical than gasoline engines. In addition, due to its higher density and oiliness compared to gasoline, its boiling point is slightly higher than that of water.
- more power
The type of combustion in these two types of engines is different from each other. Combustion in gasoline engines requires the presence of a spark plug to create a spark, but in diesel engines, the combustion process is performed by compressing the fuel and without the need for spark plugs and sparks, that is why diesel engines do not have spark plugs. The combustion type of diesel engines has made their efficiency and power much higher compared to the gasoline type.
How a diesel engine works
These types of engines are produced in different types, including two-stroke and four-stroke types. Today, its two-stroke type is not used much. The way these engines work is as follows:
The first stage includes the entry of air into the cylinder.
Then the piston condenses the air with its movement, which becomes hot due to this pressure and air density.
After the air is heated, the engine fuel is injected into it by the injector needle.
With the collision of fuel and hot air, combustion or explosion is done and causes the piston to move downwards.
How is the efficiency of the diesel engine?
In short, the diesel engine works in such a way that air enters the cylinder first. Then, by means of the piston, the air is strongly condensed in the cylinder head, and then after the air is very hot at this point, the fuel is sprayed into the heated air and exploded, then it dissolves the piston downwards.
In this case, the crankshaft turns and turns the flywheel (at this moment the car starts to move).
What is the difference between a diesel engine and a gasoline engine?
If we want to be very detailed but general and compare 2 gasoline and diesel engines with each other in the 4-stroke engines section, it is better to know:
- Gasoline engines
Gasoline engines, like diesel engines, have four parts (suction, compression, power, and exhaust).
But the difference is in the type and time of fuel injection.
First, the fuel enters the engine, then it rises and is compressed by the piston, and then the fuel is exploded by the spark plug and the power generated by the explosion drives the piston. But in diesel engines, the working process is very different (we explained above).
Also, the pollution produced by gasoline is much higher than that of diesel fuel, and for this reason, gasoline fuel is known to be dirtier than diesel fuel.
Is the diesel engine more powerful or gasoline engines?
With all the explanations given, it can be said that the power of gasoline engines is very low compared to diesel engines and in many situations they cannot even be compared.
There are many different uses of these engines in the sea sector, so that the engines of non-nuclear submarines are mainly made of diesel and can move at a distance of 3000 meters with very high pressure and with very strong currents and produce power.
Of course, nowadays nuclear and internal combustion engines or huge electric motors are used for ultra-advanced submarines, which eliminate the noise to a great extent and the enemies do not notice the presence of the submarines.
But in the maritime industry, the engines of commercial ships are mainly made of very large diesel engines, and the mechanics of these ships have to perform repairs for 2 months with a maximum of 105 mechanics to replace just one chain of this engine.
Is it more expensive to maintain diesel or gasoline engines?
Unfortunately, it must be said that yes, these types of engines are more difficult to repair due to their high technical complexity, but the main reasons for the high repair costs are as follows:
- The weight of the parts
- More workforce, sometimes up to 3 people
- Excessive wear of parts
- Mechanical and manufacturing complexity of parts
- And this is how it greatly increases the cost of maintenance and training of this engine.
