Generators are perhaps some of the most useful inventions of man. Like modern technology, they have advanced sufficiently enough that their applications have become virtually limitless. Their use has grown beyond being just mere backup power supplies for homes in case of power outages or blackouts. These days, like many of our equipment and machines, reliability, durability and portability has become the name of the game for many electrical generator manufacturers.

Generators engines come in different types based on what type of fuels they require to run them. The most common ones are gas generators and diesel generators.

While both of these types of generators are dependable in terms of performance and are basically similar in usefulness as home backup power source or as portable power source, portable diesel engines appears to have evolved into a better machine. The following are some of the reasons why this is so:

1. Generally speaking, diesel engines, especially those that are used for industrial purposes, have become more efficient and durable compared to its gas counterpart. Diesel is actually low grade oil and hence, it tends to help in protecting the internal parts of the engine. This is also true for diesel generators (which are basically run by internal combustion diesel engines). Diesel generators can run significantly longer before they require maintenance repairs compared to gas generators. For example, a 1,800 rpm diesel generator can run 12,000 to 30,000 hours before it becomes necessary to go into preventive maintenance. A 1,800 rpm gas generator, on the other hand, can only run only 6,000 to 10,000 hours before requiring maintenance checks. This may be further explained by the fact that gas engines burn a lot hotter than their diesel counterparts which can cause significant wear and tear on the units.

2. Diesel generators are also more fuel efficient than gas generators. This is because diesel engines require less engine RPM to produce the same amount of power compared to a gas-fueled generator. A 7500 watts gas generator with a 2500 rpm engine only requires a 2000 rpm diesel generator engine to produce the same wattage rating. This means less fuel consumption.

3. Diesel-powered generators have also ceased to being the noisy machines that they are famous for because manufacturers have found ways to significantly reduce their noise levels. Today, it is not unusual to find silent generator units powered by both diesel and gas. Furthermore, they have also been successful at reducing the weight and size of modern generators so those who require portability will also have a ton of options.

In summary, while power generating performance between gas and diesel power generators are just the same, diesel generators appear to have some significant advantage if you consider durability and usage for a long period of time. Other advantages that gas generators had previously have also been dissolved by good old-fashioned innovation and modern technological advancement.

If you are shopping around for a generator that you need for any application, all you need to do is determine what your power needs are as well as your budget and determine if you wish to go for gas or diesel generator types. It is good to know that both of these machines are good enough for most applications that you can possibly have for them.
