Type 3 cylinders give your vehicle a low weight gas storage. Apart from reducing the gas consumption, these cylinders also reduce the maintenance cost of the vehicle to a great extent.
The popularity of CNG has increased a lot in the last few years. Not only is it cheaper than petrol and diesel, but it also reduces carbon emissions. The speed with which the prices of petrol and diesel are increasing, it is estimated that in the coming time, the number of people using CNG will increase much more. You may also have to decide to use CNG in the coming days. So this is the right time to know about CNG and especially 4 types of CNG cylinders.
The special thing about CNG is that it expands and contracts according to the temperature around it. How much CNG can be filled inside a cylinder at a time, it depends on many things. Such as fueling rate, temperature around the cylinder, pressure rating and cylinder type. There are 4 types of CNG cylinders in the market – Type 1, Type 2, Type 3 and Type 4. Which type of cylinder depends on three things – the design of the cylinder, its method of manufacture, and its liner What is it made of?
Before getting a CNG cylinder for your vehicle, it is important for you to take care of some basic things. Type 1 cylinders are made of steel and have been in use for many years. Also, their weight is also very high. On the other hand, Type 3 and Type 4 cylinders are fully covered composite cylinders which are approximately 60% to 70% lighter than Type 1 cylinders. The liners of Type 3 cylinders are made of metal and the liners of Type 4 are made of plastic. In this article we will know the advantages of type 3 cylinder. Also, you will understand the difference between Type 3 and Type 4 cylinder.
What are Type 3 and Type 4 cylinders?
The liner of the Type 3 cylinder is made of metal and its outer surface is completely covered with composites. At the same time, the liner of the Type 4 cylinder is made of plastic and its outer surface is also completely covered with composites. It is important to understand here that both these are carbon composite cylinders. The only difference is that the type 3 cylinder liner is made of seamless aluminum alloy and the type 4 liner is made of plastic.
Type 3 cylinders give your vehicle a low weight gas storage. Along with reducing the gas consumption, these cylinders also reduce the maintenance cost of the vehicle to a great extent. Significantly, Type 3 cylinders can be easily installed in cars, light and heavy trucks, and buses.
Type 3 cylinder – a safer option
What are the benefits of using a Type 3 cylinder? What makes a Type 3 cylinder a safe alternative? Let’s understand.
1. Seamless Aluminum Liner
When the pressure in the cylinder increases, the temperature of the gas in it also increases. When the gas temperature is high, then the cylinder is not filled completely. Actually, due to fast filling of gas, more heat is generated in the cylinder and space is saved in it. The aluminum liner of the Type 3 cylinder works to reduce this heat, so that the inner space of the cylinder can be used optimally. Not only this, there are no joints or welding in the Type 3 cylinder, due to which the chances of gas leaking become negligible.
2. Collision Resistance
The external composite of the Type 3 cylinder gives it 75% to 90% strength. The rest of the strength comes from the aluminum liner. This liner is very solid. The liner does the job of protecting the cylinder and the composite from damage during a collision.
3. Heat tolerance
The heat tolerance capacity of Type 3 cylinder is very high. Because of this, more gas can be filled in it at a time. The composite fibers of the cylinder are well connected by the liner. This aluminum liner is not affected by heat, due to which the heat bearing capacity of the cylinder also increases manifold.
4. Improved fast-filling capability
Due to the rapid filling of gas, the heat in the cylinder is also generated more rapidly. In such a situation, the cylinder does not get time to reduce this heat. Type 3 cylinder is a better option for fast-filling as the thermal conductivity of its aluminum liner is very high. Because of this, the cylinder can be completely filled with gas even during fast-filling.
5. Burst Safety
Safety is the most important thing to keep in mind while getting a CNG cylinder fitted in your vehicle. Natural gas contains many aggressive components, which increases the chances of rusting of the cylinder. But due to the corrosion resistance of the aluminum liner of the Type 3 cylinder, this cylinder is protected from corrosion. In this way both the vehicle and the passenger remain safe.
Conclusion
Type 3 cylinders are manufactured in accordance with ISO11119-2. High-strength carbon fiber and epoxy composite are used to make them, as its liner removes heat from the cylinder, allowing more gas to be filled in it. Also the Type 3 cylinder improves the driving range without increasing the weight of the vehicle. Looking at its many benefits, we can say that Type 3 cylinder is a safe and great option for your vehicle.
