The diesel power generator is a robust piece of equipment that converts mechanical energy into electricity through an engine and an alternator.
Its application ensures energy security in industries, hospitals, and events, making the rental of diesel power generators the smartest choice to reduce costs and have specialized technical support.
Understanding the technical operation and the main components that ensure efficient energy conversion, the strategic advantages, and the savings provided by using diesel and biodiesel generators in different operations is increasingly strategic for decision-making.
What is a diesel power generator and how does it work?
The basic operation of a diesel power generator occurs when the internal combustion engine burns the fuel to rotate a central shaft. This movement drives an alternator that, through electromagnetic induction, generates the electrical current needed to power the equipment.
Main components of the diesel generator and their functions
The main components of the diesel generator, as well as their functions, are:
– Engine: is the heart of the system, responsible for converting diesel into rotational mechanical energy.
– Alternator: transforms the engine’s mechanical energy into electrical energy through magnetic fields.
– Control system: smart panel that monitors performance and protects the generator against technical failures.
– Tank and Exhaust: the tank stores the fuel, while the exhaust treats and releases combustion gases.
What are the advantages of a diesel power generator?
Choosing the right energy source directly impacts profitability and the continuity of production processes. The mechanical robustness of these devices allows them to operate in harsh conditions for long periods.
- High power to support heavy machinery loads and large infrastructures.
- Greater engine durability, requiring fewer interventions compared to gasoline models.
- Lower operational cost in intensive use regimes due to superior thermal efficiency.
Types of diesel generators and their applications
There are several types of power generators on the market, each suitable for a specific mobility and load scenario. The right choice involves a technical understanding of each client’s needs.
A stationary diesel generator is ideal for fixed installations that cannot experience interruptions, such as data centers.
On the other hand, the three-phase diesel generator is the standard for industries, as it provides stable energy for large electric motors.
For versatile needs, the dual voltage diesel generator offers the flexibility of different voltages in a single device.
Tecnogera has modern models, including the automatic diesel generator, which starts operation instantly during power outages.

How to calculate the ideal kVA power of the generator for your operation?
The sizing correct is essential to avoid overloads or fuel waste in an industrial plant. An accurate calculation considers the sum of all the power of the devices that will be connected simultaneously.
To know how to size the diesel generator, you must add the power in Watts of all the equipment and apply the power factor. It is essential to consider the starting current of motors, which can be up to three times higher than the nominal.
Tecnogera’s engineering, composed of highly specialized professionals, performs this detailed survey to ensure that the project does not suffer from undersizing. We offer from the 10kva diesel generator for small loads to megawatt systems for large industries.
Most common diesel generator power ratings and their typical applications
Choosing the ideal power rating is essential to ensure the continuity of operations and the safety of connected equipment. Check below for the most commonly used capacities in the market and their main usage recommendations.
- 15kva Diesel Power Generator: ideal for small businesses, offices, and medium-sized food trucks.
- Generators from 100 to 500 kVA: applied in large construction projects and medium-sized events.
- Generators above 500 kVA: used in petrochemical industries, large hospitals and mining.
The importance of AVR in electrical stability
The Automatic Voltage Regulator (AVR) is a device that protects sensitive electronics by maintaining a constant output voltage. It compensates for load fluctuations in the stationary diesel generator, preventing voltage variations from damaging computers or hospital equipment.
Technical standards and legal requirements for diesel power generators
The installation must strictly follow NBR 5410 to ensure safety low voltage electrical installations. Additionally, exhaust standards are essential for controlling gas emissions in inhabited areas.
The installation of generators in enclosed spaces without ventilation systems designed by specialists is prohibited. Qualified engineering ensures that the entire project complies with current environmental and safety laws.
Maintenance of diesel power generators
The preventive maintenance of the generator diesel includes periodic checks of oil, fuel filters, and battery condition. Tecnogera’s 24-hour support ensures your operation has full availability, acting quickly at any sign of wear.
What is more cost-effective, buying or renting a diesel power generator?
The analysis of diesel generator purchase prices shows that acquisition involves high costs and maintenance. By opting for renting a diesel power generator these fixed expenses are eliminated, turning the investment into a deductible operating expense.
Renting a generator with Tecnogera guarantees access to a modern fleet and end-to-end engineering support. Additionally, you don’t have to worry about asset depreciation or the technical management of the equipment.
What are the differences between open and enclosed diesel generators?
The silent diesel generator is the enclosed type, featuring soundproofing for use in urban areas or events. Open models, on the other hand, are suitable for isolated machine rooms where noise does not affect neighbors or employees.
What is ATS and why use it in emergency systems?
The ATS, or Automatic Transfer Switch, detects a failure in the public grid and starts the generator without human intervention. This system is essential for maintaining business continuity in cases of unexpected blackouts, ensuring total autonomy.
The role of BESS in hybrid temporary energy
The BESS system (Battery Energy Storage System) works in conjunction with diesel to create efficient hybrid systems. It stores energy and reduces engine use during periods of low demand, drastically cutting the carbon footprint.
Tecnogera uses this innovation to offer solutions that combine the power of diesel with the sustainability of batteries. This allows for cleaner, quieter operation with significant savings on power generation.
How are biodiesel and new technologies changing the energy sector?
Biodiesel and technological innovations are transforming the energy sector by offering alternatives that combine high performance with environmental responsibility. As a renewable fuel, biodiesel significantly reduces greenhouse gas emissions and particulate pollutants.
In generator operation, it brings clear technical benefits, as it acts as a natural lubricant for the system. This helps reduce friction and wear on sensitive parts, such as pumps and injectors, which increases engine durability.
Furthermore, being less flammable than fossil diesel, it makes handling and storage much safer, facilitating compliance with environmental standards.
Tecnogera follows this evolution with 20 years of market experience, focused on innovation and commitment to ESG goals. Our modern fleet is designed to offer maximum power with lower fuel consumption, including options powered by biodiesel and natural gas.
Furthermore, we expand this sustainable vision to our division of aerial platforms, which is 100% electric and uses lithium batteries, eliminating noise and emissions in high-altitude work.
