Today's CNG Price in Chittoor

Engine Life 

CNG increases the shelf life of the car engine and is considered to be a better option than petrol. The engine life is unaffected if the car has a factory installed CNG kit. Thus, the engine life of a petrol and a CNG vehicle is comparable. 

The ECU (Electronic Control Unit) is a device that allows for precise fuel supply control in current CNG vehicles with factory installed CNG kits. Additionally, the engine parts have been specially created for CNG fuel. Consequently, there is no reduction in engine life. To acquire the most engine life, one must properly maintain the vehicle.

Maintenance 

With the exception of the CNG kit, which includes the CNG tank, fuel lines, etc., CNG and petrol cars have mechanical parts that are equivalent. Both CNG and petrol cars require the same fundamental maintenance. A CNG vehicle, however, needs extra attention because it has a few extra parts. 

Since CNG is a very flammable fuel, regular upkeep of the CNG kit is crucial. The CNG tank and fuel lines must be routinely inspected for any signs of deterioration. To prevent any gasoline leakage, components must be replaced on schedule. The remainder of the car's service is identical to that of a petrol vehicle. 

Storage of CNG  

Reciprocating compressors are used to compress natural gas to 250 Bars. Natural gas that has been compressed is referred to as CNG. It is kept in a stationary cascade, which is a collection of cylinders, at the mother station or online station.

CNG Cascade 

On an iron structure, a group of cylinders are stacked in a waterfall-like pattern which is known as Cascades. These cylinders are constructed using iron, aluminium lining, and carbon fibre wrapping in accordance with a certain standard and procedure. Each cylinder is produced and tested in accordance with strict regulations according to The Petroleum and Explosives Safety Organization (PESO).  

Some of the types of cascades are given below: 

1. Type-1 Cascades: According to PESO, cylinders used in Type-1 cascade must be designed, built, and tested in accordance with the most recent version of IS 7285, BS 5045: Part-1, or (US) D.O.T 3AA. The material of the cylinder shall be seamless alloy steel (Cr-Mo), and the neck threading and thread must both comply with IS: 3224-1979. Closed valve must verify IS: 3224. Due of their affordability, type-1 cascades are common in Indian City Gas. To transport CNG from the mother station to the daughter booster stations, these can be employed as permanent or movable cascades. 
2. 3000 water liter cascade: The most often utilised stationary cascade at CNG Stations is the 3000 WL cascade. It consists of 40 cylinders, each holding 75 litres of water. It can store about 530 kg of compressed natural gas at 250 bar and 0.7 kg/litres of gas density. This amount may vary from location to location. This is dependable because of its durable design, production, and testing. Because of its low cost, it is practical. 

1. 4500 water liter cascade: A well-liked mobile cascade for transporting CNG from the mother station to the daughter booster stations is the 4500 WL cascade. It has occasionally been utilised as a stationary cascade to store additional CNG. It can hold about 630 kg of CNG, which can be filled and transported at 200 bars with a gas density of 0.7 kg per litre. This is dependable because of its durable design, production, and testing. It is currently the most popular cascade among mobile cascades. 
2. Type 2 Cascade: Type-2 cascades are made of metallic cylinders that have partial, not complete, wrappings around them. Typically, wrapping is made of glass or carbon that has been mixed with epoxy or resin. Utilising non-metals has helped to reinforce it while reducing weight but increasing expense. 
3. Type 3 Cascade: These cylindrical metal liners have a full outside wrap of composite reinforcement with fibres applied in full hoop and circumferential and helical and axial parts. Also, there are two of these. One is composed entirely of carbon composite, while the other combines carbon composite with glass fibre wrapping. These cylinders are used to hold more CNG and make cascades lower in weight. These are expensive. 
4. Type 4 Cascade: Type 4 cylinders are made of a composite of HDPE and carbon fibre. This combination makes the cylinders extremely light and able to store the most CNG possible. Mobile cascades can now use Type-4 cascades in place of Type 3 and Type 1 cascades.
