Diesel Generator
Frequently Asked Questions

Diesel generators are one of the most common forms of standby power in the world.

A diesel generator produces electricity through a combination of a diesel engine with an electric generator. The power of the diesel generator is transformed by the alternator into a usable electrical current. This reliable source of power is often used by many businesses and homes for protection against power failure.

Diesel generators are commonly used by a variety of different organisations including data centers, banks, hospitals and factories. It’s vital to take action on your power back-up - no business is too big or small to have a diesel generator solution in place.

A UPS system will provide power protection during power disturbance and blackouts, but it is not designed to deliver backup power indefinitely – if your business’s critical power source must remain online, a standby generator is crucial to assist your existing UPS system.

Diesel generators are more reliable. The easiest way for me to explain it is this. Diesel fuel is basically a light-grade oil. Inside any internal combustion engine, there are many moving parts that create friction. Gasoline and propane are solvent-based fuels which promote friction and wear. Diesel, being a lubricant, reduces friction and wear. If you ever need to do work on a Diesel engine, they are simple. All you need to make a Diesel run is air-compression and fuel. Diesels don’t need sophisticated (and failure-prone) ignition systems; no spark plugs, no points and no carburetor!

With proper maintenance, a high-quality Diesel Generator will last indefinitely. It is important to change the oil regularly and keep the air filter clean. Clean fuel is extremely important.

Although it is often referred to as a generator or alternator, we only use brushless alternators. The beauty of a brushless alternator is that it only has one wear item – a sealed ball-bearing that is rated for 100,000 hours.

Absolutely, Hardy offers generator sizing, power calculators and conversion tools for estimating in addition to providing general input on your generator sizing and product selections. However, nothing can replace an on-site visit by a local licensed electrical contractor to help understand your power needs, voltage requirements, installation, distances, wire size, voltage drop, elevation, and more.

The continuous running time of a diesel generator depends on various factors such as the generator’s design, load capacity, fuel tank size, and maintenance. Diesel generators are typically designed for continuous operation and can run for extended periods if properly maintained.

Modern diesel generators, such as Escorts diesel generator, can often run continuously for 8 to 24 hours or more without interruptions, provided there is a continuous fuel supply and the necessary maintenance is performed. Some larger industrial-grade diesel generators have larger fuel tanks and can run for several days without refuelling.

The efficiency of diesel generators in India refers to the ratio of the electrical energy output to the fuel energy input. The best efficiency for a diesel generator depends on various factors such as the design, size, and load conditions. Generally, modern diesel generators can achieve an efficiency ranging from 30% to 45%.

The efficiency of a diesel generator is highest when it operates near its rated load capacity. Running the generator at a partial load can decrease its efficiency since the fuel consumption remains relatively constant while the electrical output decreases. It’s important to match the generator size to the expected load to maximise efficiency.

The Central Pollution Control Board (CPCB) sets emission standards for various categories of generators to control air pollution. The progression from CPCB II to CPCB IV+ signifies a significant leap in environmental performance and operational efficiency.

Emission Reduction:

Nitrogen Oxide (NOx) Emissions: CPCB IV+ compliant generators substantially reduce NOx emissions compared to their CPCB II counterparts. This not only aligns with environmental regulations but also contributes to cleaner air and a healthier environment.

Improved Fuel Efficiency

Advanced Engine Technology: CPCB IV+ generators leverage advanced engine technologies to enhance fuel combustion efficiency. This results in better fuel economy, reducing operating costs over the long term.

Lower Particulate Matter (PM) Emissions

Enhanced Filtration Systems: Upgrading to CPCB IV+ ensures more efficient particulate matter filtration. This is crucial for industries operating in diverse environments, as it minimizes the impact of airborne particles on both equipment longevity and air quality.
