Diesel Generator Vs Petrol Generator: Which is Best Suitable for You?

When it comes to comparing generators – there can’t be any more vital comparison call than Diesel Generator versus Petrol Generator.

The comparison is made on every possible platform – be it worksites, houses, businesses, outdoor actives, construction sites and agriculture farms across Australia.

Here at All Generator, we know for a fact that diesel generator is one of the most cost-effective and fuel-efficient units you can buy. But petrol generators have come of age and are taking on diesel generators at their own game. So, who will reign supremacy? Together we’ll be the judge of that…

Advantages of the Diesel Generators

Owning a diesel generator is a cost-effective decision. That’s the reason we see the diesel generators used commonly by businesses and households alike. The engines used in the diesel generators are sturdier, long-lasting and hence value for money. The reason for these engines lasting longer is that mechanical wear and tear of such engines is significantly less in comparison to the petrol engines with the same output of power. The diesel engine components face less stress in the process of power production as the diesel is self-lubricating.

Secondly, the non-reliance of diesel engines on an ignition system makes it less prone to failing to start. The engines can run at the 60 to 100 % of loads for an extended period which makes it more attractive than the petrol engines. The fact that the diesel engines are more fuel-efficient makes them an even more viable option.

Thus, being a hassle-free, fuel-efficient and powerful engine, the diesel generators make their presence felt not only on smaller load areas of domestic appliances back up but also the heavy industries like construction, agriculture and mining.

Disadvantages of Diesel Generators

One of the main cons of the diesel generator is that these emit more toxic gases like carbon dioxide and carbon monoxide (CO2 & CO) per litre of fuel than their petrol counterpart. Although as these are more efficient, so in the longer run, with these consuming lessors fuel the emission rates might be comparable.

Another factor is that diesel has always been more expensive in Australia. Also, the breakdown chances are less, but fixing costs may be higher when required.

 

Advantages of Petrol Generators

Apart from the fact that the petrol generators are cheaper, these generators also come in a wider range of models. The petrol gensets are usually significantly quieter than their diesel counterparts.
Thus, this category is best suited for lighter, in-frequent and in-door usages rather than their bulkier diesel compatriots.

Disadvantages of Petrol Generators

Petrol being more volatile than the diesel, it becomes riskier to operate the petrol generators if one carries or stocks the fuel. Also, these engines rely on the spark ignition, which increases the risk of explosion and requires more maintenance.

Again, the thermal temperature of the petrol engines increases more rapidly than the diesel engines leading to more stress and the wearing of the components of the engine. That is the reason that petrol engines have a shorter life. The maintenance costs are kept to a minimum by running these engines at lighter loads and for shorter periods of time. 

CONCLUSION

After going through the above points, most of the buyers would definitely be going for diesel generators, but the main thing to consider is the “USE” that you shall require the generator for. While for the high and extended power demand, diesel engines are more suitable. On the other side, for small scale usage, the more reasonably priced portable petrol generators can work wonders.
