Types and advantages of CNG car

CNG (compressed natural gas), It is made by compressing natural gas, which consists mainly of methane, into a high-pressure form so it can be used as fuel in vehicles. It is a cleaner and cheaper alternative to traditional petrol or diesel. Let us see some of the benefits of CNG car.

1 ) Cost Savings: Compared to petrol and diesel, CNG is significantly cheaper. The cost of filling the vehicle is reduced significantly which means that if the vehicle is used frequently then CNG is the ideal choice.

2) Reduced Levels of Air Pollution: Due to the fact that CNG burns cleaner, the emissions made in the use of CNG are cleaner which means it will be able to help with Carbon dioxide and Nitrogen oxide gasses which means less aid in pollution.

3)Cleaner Engines: The Usability of CNG means that it produces a significantly lesser amount of carbon deposits which means less damage and wear and tear on the engine which means more use of the engine for a longer time.

4)Smoother Drives: Cars that run on CNG make the Garage sound much quieter which means driving the car becomes a more relaxing and enjoyable experience as due to the significantly quieter engines, the cabin noise will also reduce.

5)Increased Mileage: Cars that are powered by CNG are significantly more fuel efficient meaning that while it is true that they have a slightly less range when compared to diesel-powered cars, the mileage when driven gives aid to the overall need of gas if operating conditions remain the same.

6)Green Energy Transition: It is to be acknowledged that Natural Gas is cleaner and CNG is now being made to bridge the gap in transitioning into more sustainable means to help with the degradation of the Earth.

Overview of the types of CNG kits

Choosing the right CNG is essential when you are converting your car from petrol to CNG ,the right kit depends on your driving habits, budget, and car engine. Here are the different types of CNG kits available and their features.

1. Sequential CNG Kit (Sequential Injection Kit)

The Sequential CNG Kit is one of the most advanced systems. It injects CNG into each cylinder of the engine in sequence, just like modern petrol engines inject fuel. The system uses an electronic control unit (ECU) to manage the flow of fuel.

Why It’s Great: 

–Efficiency: This kit helps you get better fuel economy and smoother performance from your car.

– Engine Health: Because it precisely controls the fuel flow, there’s less engine wear.

– Power: It maintains your car’s power and performance, making it almost as good as running on petrol.

Best For: -Newer cars with fuel injection systems. If you have a modern car, this is likely the best option.

2. Venturi System (Carburetor-based Kit)

How It Works:

The Venturi system is simpler and works by mixing the CNG with air before it enters the engine’s intake. It’s an older system and uses a carburetor to combine the two fuels.

Why It’s Great:

Affordable- This system is cheaper to install and more budget-friendly compared to the more advanced options.

Simplicity-  It’s a tried-and-tested system that works well with older cars.

Best For: – Older cars with carburetor engines. If your car isn’t modern, this is a cost-effective option to convert to CNG.

3. Liquid Phase CNG Kit

How It Works:

In this system, CNG is stored in liquid form and then injected directly into the engine. Once it enters, it turns back into a gas, helping the engine burn fuel more efficiently.

Why It’s Great:  

Better Mileage: Liquid CNG has a higher energy density, meaning you get more mileage out of each tank.

Improved Efficiency: The system enables your car to use less fuel.

4. Bi-Fuel CNG Kit

How It Works: 

This system allows the user to use both petrol or CNG and switch between them as per their need.

Why It’s Great: 

Flexibility: If one cannot find a fueling station they can convert to petrol, if they run out of petrol they can convert to CNG.

Range: The added advantage of two fuel options, makes sure you are never stuck and enhances range.

5. Dual Fuel CNG Kit

How It Works:

Similar to the Bi-Fuel system, this system helps in auto-switching the two fuel modes in car.

Why It’s Great: 

You don’t have to think about which fuel you’re using—it switches automatically for maximum convenience.

Best For: 

Drivers who want a seamless experience.

This pretty much summarizes types of CNG kits.

Choosing the Right CNG Kit for Your Car

Type of Car: Is your car new or old? If your car is newer with a fuel injection system, a sequential kit is likely best. Older cars with carburetors work better with the Venturi system.

Budget: Sequential kits tend to be more expensive, but they offer superior performance. Venturi systems are cheaper but still effective for older cars.

Driving Habits: If you drive long distances or need flexibility, a bi-fuel or dual-fuel system is a great choice.
