Why Diesel Generators are the Ultimate Solution for Power Outages! What is diesel generator, how it works and what are its main parts. Let us know in detail about the diesel generator.
Diesel generators ie DG are used in those places where we do not get electricity, or it is for a short period of time. It is also used for power needs in case of emergency. For example, if the mobile tower is getting supply from the power grid and it is disconnected due to some reason, the diesel generator automatically starts running so that there is no power issue at the tower, and we get continuous network.
What is diesel generator
A diesel generator is a device composed of a combination of a diesel engine and a generator. Inside it is a diesel engine, which burns the diesel, and the combustion provides rotational power to the dynamo (alternator). Now with the rotating power of this dynamo, we can run any electrical appliance.
Diesel generators are used in many places such as – in companies, constructions, hospitals, offices and homes.
Types of diesel generator
Diesel generators are divided into three parts on the basis of use.
- Portable Generator– This portable generator is mainly used to run small appliances. This generator uses gas and diesel fuel to power us; this portable generator is only used when temporary power is needed.
- Inverter generator– This generator uses the help of an alternator, which is coupled to a diesel engine, to produce electricity. But the difference in this inverter generator is that it gives power from three phases. Inverter generator is first used in AC supply form, then it is converted into DC current and finally this DC current is converted into AC current.
- Standby Generators– You all must have seen generators installed in your company or any office around your house, most of the time they are standby generators. These generators are used for emergency power supply. These become available in the market in very high kVA power.
Diesel Generator Parts and their Functioning
Engine– Its function is to provide mechanical power to the alternator to rotate the alternator. And rotating the alternator generates electricity.
Diesel tank– Diesel tanks are used to store diesel. A diesel tank is mostly of 500 to 1000 litres.
Primary lubricant oil pump– This equipment is used to transport the lubricant oil everywhere. So that all parts of the machine can work smoothly.
Lubricant oil filter- Lubricant oil are used to reduce friction. If any garbage gets accumulated in the Lubricant oil, then Lubricant oil filte works to remove it.
Oil filter- Sometimes it happens that there is a little waste in the diesel. It is used to remove that waste. This prevents that waste from entering the diesel engine.
Fuel Water Separators– Many times diesel generators are kept in open places. When the rainy season comes, there is a fear of water getting into the fuel. Hence, to avoid this problem, fuel water separator is used. Its function is to separate water from the fuel.

Air Filters– DG requires air to run. Air filters are used to prevent dust from coming in with this air.
Turbo Charger– The job of a turbo charger is to get the air into the engine after it is filtered. Along with this, the job of turbo charger is to remove the carbon dioxide produced in the engine from the engine.
Actuator– With the help of an actuator, we get to know how much diesel to put into the diesel generator engine as per the load.
Coolant tank– This tank is used to store distilled water/coolant. When the engine is running, the lubricant oil heats up. It is very important to cool this oil. Distilled water is used to cool it.
Radiator and Fan- When the engine runs for a long time, the distilled water gets heated along with the engine. Fans and radiators are used to keep it cool.
Silencer– When the diesel generator runs, it makes a lot of noise. Silencers are used to reduce that sound.
Alternator– Alternators are used to produce electricity. Coupling is used to connect the engine and alternator. When the engine rotates, the coupling causes the alternator to rotate as well.
Cranking Motor / Starter Motor / Battery– The battery fits inside the diesel generator. When the diesel generator starts, a cranking motor is used to accelerate it. After the diesel generator starts, the cranking motor automatically stops.
Control panel– With the help of this we can set the diesel generator to run on or off or automatically. There is also a display on top of it, in which we can see DG reading, output voltage, frequency, ampere etc.
Automatic voltage regulator– It is used to correct the voltage of DG whenever the voltage of DG is less or more.
Circuit Breaker– This circuit breaker protects our equipment from damage if accidentally shot circuit or any type of electrical fault occurs inside the diesel generator.

How to choose best diesel generator for me?
Choosing the best diesel generator for your needs requires careful consideration of several factors. Here are some steps to help you make an informed decision:
- Determine your power requirements: Start by assessing your power needs. Make a list of the appliances, equipment, or machinery you need to run during an outage or in remote locations. Calculate the total wattage or kilowattage required to power them all simultaneously.
- Consider the generator’s power rating: Look for a generator with a power rating that exceeds your calculated power requirements. This ensures that the generator can handle the load without being overloaded.
- Identify the runtime needed: Determine how long you need the generator to run continuously. Consider the fuel capacity and fuel efficiency of the generator. Calculate the expected runtime based on these factors.
- Assess the generator’s size and portability: If you need a generator for portable or temporary use, such as camping or construction sites, consider a portable or inverter generator. These are compact and easy to transport. For standby or backup power for your home or business, a larger stationary generator may be more suitable.
- Check the quality and reliability: Research different brands and models of diesel generators. Read reviews and ratings from reputable sources to assess their quality and reliability. Choose a generator from a trusted manufacturer with a good reputation for producing durable and efficient generators.
- Consider fuel availability: Diesel generators require a constant supply of diesel fuel. Ensure that diesel fuel is readily available in your area. Check the fuel consumption rate of the generator to estimate the fuel costs.
- Evaluate the generator’s noise level: Noise can be a significant factor, particularly if you plan to use the generator in a residential area. Look for generators with noise-reducing features such as soundproof enclosures or low-noise designs.
- Examine the safety features: Look for generators with safety features like circuit breakers to protect against electrical faults and automatic voltage regulators to stabilize the power output.
- Consider after-sales support and warranty: Check the warranty offered by the manufacturer and the availability of authorized service centers in your area. Good after-sales support is essential for maintenance and repair requirements.
- Set a budget: Determine your budget range based on the power requirements and expected usage. Compare prices from different suppliers and choose a generator that offers the best value for your money.
Following these steps will help you choose the best diesel generator that meets your power needs and provides reliable performance.
