Home owners and large operations such as processing and manufacturing industry, hospitals and call centers need a bountiful and a constant supply of electrical power. Rather than installing a very expensive, permanent power backup system, generators are used to fill the gap when there is power blackout. While there are generators fueled by biofuels, solar, geothermal wind, and liquid propane, we will explore the advantages and disadvantages of gas and diesel generators. Which is better, gas or diesel?
Fuel Efficiency
Diesel generators use less fuel than their counterpart gas generators. Because compression ignites the fuel, and air and fuel are introduced into the diesel engine separately. Thus only air is compressed, this allows engine too use less fuel.
In contrast, gas generators mixes air and fuel together before compression and thus there is less fuel efficiency. And thus on the same amount of fuel, diesel will run longer.
Noise and Heat
Diesel generators are not suitable for high density neighborhoods because they are noisy. With improved tech, diesel generators are becoming friendlier, they lack carburetors or spark plug and thus they are quiet.
Diesel units are more durable than their counterpart. They are always more compact. Gas also burns hotter than diesel and thus they have shorter lifespan.
Cooling
Generators can be liquid cooled or air cooled. Liquid cooled generators are the best and can be used for larger projects. Diesel cooled generators are used to provide power back-up for larger projects because they are mostly liquid cooled, and can remain in use for more than 12 hours. In other hand, gas generators are air cooled and they cannot remain in us for more than 12 hours.
If you want short term power outage generator, you may consider using gas generator.
Cost
Diesel generators are always expensive. This is justifiable because diesel generators will use up to 35% less fuel, they are more durable and maintenance cost is usually low.
Buying a generator can be simple if you know the number of appliances it will power, your budget and if it will be used for short term or extended use.
Gas generators are more environmental friendly than diesel generators. Gas generators are cleaner than diesel generators and don’t require exhaust cleaning.
It is clear that gas generators should be used for smaller jobs (where less than 200 than horse powers are required), and should not be used for than 12 hours. For any other application, a diesel unit is the best choice.
