Types of LPG tanks

Gas installation is one more effective way to reduce the cost of a car. Unfortunately, this involves the need to install an additional tank to which the gas fuel can be refueled. Such modification usually results in lower utility and aesthetic values ​​of the vehicle. This is why LPG tank manufacturers offer several types of cylinders so that everyone can choose the right model for their vehicle type and preferences. Let’s see what are the pros and cons of these solutions.

Cylindrical tanks

Cylindrical (cylindrical) cylinders were very popular in the 1990s, when they were not particularly weighted for aesthetic reasons, and the gas system was simply designed to work and provide a long range. This task cylindrical tanks fulfilled in 100% Their construction guaranteed optimum capacity, so visits to the station were much less frequent. The bottle was usually placed transversely just behind the back seat, which unfortunately limited the capacity of the trunk and the ability to carry long objects.

Currently, tanks of this type are assembled very rarely – we find them mostly in pickups or off-road vehicles, which due to high combustion require high-capacity cylinders.

Smaller versions of cylindrical tanks can be found in cars fitted with small luggage. Their capacity usually does not exceed 30 liters, and the assembly is longitudinal to the left or right. This allows you to make the most of your remaining trunk space, and you can carry longer items when you fold the rear seat backrest.

Bottles of this type are an alternative for vehicle owners where an internal toroidal tank can not be fitted. This is the case, for example, in some French cars, where the spare wheel is placed in a basket beneath the floor of the boot. The smallest cylindrical tanks generally have integrated attachments, but for larger models we will need to buy a rack.

Toroidal tanks

Toroidal tanks are by far the most common solution used in automotive LPG installations. Typically, they are located in a spare wheel bay, so they do not limit the use space. In this case, “stock” is placed in a protective case and carried in the trunk. This is not a problem, however, because the wheel can be removed or retracted at any time. Another exit is buying a driveway or repair kit.

The capacity of the toroidal tank is strictly dependent on the size of the bay for “stock”. If we want to use it to the maximum, it may be necessary to remove some fixing elements. To avoid this, we will have to choose a slightly smaller reservoir.

Toroidal tanks, like their cylindrical counterparts, are also available in the outer version. Typically, they are used in cars whose spare wheel is suspended under the floor of the boot. After disassembling the bin for “reserve”, the ideal place for the LPG cylinder is created. This solution will also work in SUVs and off-road vehicles where the wheel is located on the tailgate. External toroidal tanks, depending on the variant and manufacturer, have integrated attachments or dedicated clamps.

LPG tanks are available in many variants, so you can easily buy a model tailored to your vehicle and our expectations. This is extremely important for later use because it affects the vehicle’s range and luggage functionality. For many people aesthetic considerations are also important – the transparent installation of LPG cylinders can effectively discourage the installation of gas. Therefore, before we put the car into the workshop, we should consider all options, bearing in mind the advantages and disadvantages of each.
