Even the most seasoned of generator users are sometimes taken aback when they realise just how complex and intricate the inside of diesel generators are. Even the smaller units are incredibly complicated, and this is why they require top-tier care and attention. Here at Generators Online, we have made a name for ourselves by acting as a retailer for some of the most well-known brands in this industry. This experience means that we are well-versed in the different components; as such, we are delighted to be able to walk you through what we consider to be the most important of these.

Fuel Tank

If you want to be able to use your generator at all times throughout the day, it is important that you ensure that your unit is equipped with a fuel tank that is rather large in size. Despite diesel engineers being more efficient than their petrol counterparts, they are still known to be guzzlers of fuel, particularly when left on for extended periods. When you are searching for a potential source of backup power, it is advisable that you enquiry about the fuel tank, both in relation to its placement and its capacity.


In case you weren’t aware of the internal workings of modern generators, you may be interested to learn that the majority of these are fitted with miniature motors. These are used to power the smaller moving parts; without this, your generator would not be able to operate in an efficient manner. A helpful maintenance tip, in regards to your battery, is that you attach a trickle-charger whilst it is not in use. The knock-on effect of this is that even if you leave your generator for an extended period of time, it will smoothly-and-seamless be able to function as-and-when it is required.


Without this particular component, you would be left with a hulking great machine that, for all intents and purposes, is redundant from a practical sense. Inverter generators that are of the highest-quality are typically powered by diesel engines – in many ways, these are similar to the combustion engines that are found under the bonnets of road vehicles. As is to be expected, if your unit features a larger engine, this means that its power output will be substantially more than a smaller portable generator.

Exhaust System

Due to the large quantities of electricity that is created during a diesel generator’s operation, it should come as no surprise to hear that there is a vast amount of heat that needs to be vented out. Failure to do so will create an imbalance within this engine, and this is where faults arise. Power supplies such as these must be equipped with sufficient exhaust systems, as overheating is one of the most common and damaging problems commonly associated with both diesel and petrol generators. You need to take precautionary measures to ensure that you don’t encounter this type of problem further down the line.
