Diesel Generators vs Gasoline Generators

We often get asked “Are diesel generators better than gas ones?”

Most communities across the world are dependent on electricity to power their lives. Domestically we rely on electricity for lighting, heating, air con, fridges, washing machines etc. In industry, the main dependants are computers and machines which run the business.

Then there are places like hospitals where essential services need electricity, not to mention the various machinery which modern hospitals use to analyse patient’s situations and keep them alive, then there are things like x-ray machines used to diagnose a patient’s illnesses.

When the mains fail, backup generators play a vital role in supplying electricity. There are many types of backup generators available in the market among which the most popular are diesel engine generators. These generators can be used for both business and home purposes. When purchasing a generator, make sure to check the pros and cons of each generator.

The following article explores the comparison between Diesel Generators & Gasoline Generators based on several factors and answers the question “Are diesel generators better than gas ones?”:

1. Efficiency

The efficiency of diesel generators is better than Gasoline ones as the former uses less fuel than later ones. In a diesel generator, compression ignites the fuel. Here the fuel and air are introduced into the engine separately. Due to the compression of air the engine runs more efficiently by using less fuel. Thus, diesel generators will run for a longer period. Also, they are cheaper than gasoline and provide uninterrupted service to your office or home.

Contrast to this, in gasoline generators, the fuel & air are mixed together in a carburetor before compression which leads to a reduction in fuel efficiency.

2. Noise & Heat

The old models of diesel generators were noisy and were unsuitable for use in high-density regions. But the latest models of diesel generators make less noise and require less maintenance. An 1800 rpm water cooled diesel generator will run for 12k to 30k hours before it requires any major maintenance.

On the other hand, gasoline generators require more maintenance. They will need service after 6k to 12k hours of operation. Since gasoline burns hotter than diesel, it results in more wear and tear on the generator parts.

3. Safety

Gasoline generators use spark plugs to ignite the air mixture used during the combustion process. This indeed can pose a danger if the machinery is not maintained well. On the other hand, diesel generators create combustion through the compression process which heats the fuel and ignites it. This proves to be safer than gasoline engine as there is no spark that will cause an explosion. Thus, diesel generators are safer than gasoline ones.

4. Cost Comparison

A diesel generator typically costs more than gasoline generator, mainly because of its robust nature. However, if properly maintained, the investment in a diesel generator can turn into real savings over time. There is an eventual breakdown in gasoline generator because of its more complex nature and heats involved in it. Eventually, gasoline generators need replacement.

From the above comparison between diesel and gasoline generators, we conclude that diesel generators prove to be more beneficial. Diesel generators are more productive and cost-effective over a longer time. Companies like Eagle Generators offer efficient new and used diesel generators for sale in the UK at affordable prices.

So we hope we have answered the question “Are diesel generators better than gas ones?” But if you feel you have more questions, do not hesitate to get in touch.
