Since the termination of the petrol subsidy in Nigeria, many car owners are seeking for ways to minimize fuel expenses by converting petrol-powered vehicles to run on compressed natural gas (CNG).
CNG is viewed as a more cost-effective and ecologically friendly alternative to gasoline. To assist this transition, the Nigerian government, backed by President Bola Tinubu, established the Presidential Compressed Natural Gas Initiative (PCNGI) in August 2023.
The PCNGI seeks to make the conversion process easier and more accessible to Nigerians. They have established CNG conversion centers throughout the country and implemented the “Transport Fare Drop Programme” to help lower commuting costs.
In October 2024, the federal government created a website for converting petrol-powered cars to CNG with a “pay-later” option. This means you may convert your vehicle today and pay for it in manageable monthly installments.
As it goes, If you’re thinking about switching your vehicle to CNG, here are five things you should know before making the switch:
1. Not all vehicles are suitable for conversion for CNG
While many petrol-powered vehicles can be converted to run on CNG, not all are ideal candidates. Passenger cars, light commercial vehicles, and some buses can usually make the switch.
However, high-performance vehicles and older engines may face challenges. Generally, vehicles less than 10 years old with modern systems are better suited for CNG conversion. Turbocharged or high-powered engines, on the other hand, might not be compatible with CNG systems.
When converting a petrol car, key parts such as a storage cylinder, pressure regulator, CNG tank, and heating system are added to allow it to run on CNG. Diesel engines, however, work differently. They can only partially switch to CNG, running on a mix of diesel and CNG rather than solely on CNG.
2. Your vehicle’s age and condition matter
Your car’s age and condition have a significant impact on whether it’s suitable for conversion. Cars in good condition and less than ten years old are usually better suited to CNG conversion.
Vehicles with near-end-of-life engines or those with mechanical faults may struggle to handle the switch.
Before converting, have a trained mechanic evaluate your vehicle to guarantee it can withstand the demands of a CNG system. This procedure can help prevent future issues and guarantee that your car operates well following conversion.
3. Consider emission standards
One of the benefits of CNG is that it produces fewer emissions compared to petrol, making it a more environmentally friendly fuel option. However, in Nigeria, your vehicle needs to meet specific emission standards before it can be converted. Older cars that do not meet these specifications may not be eligible for conversion.
It’s a good idea to consult with a CNG conversion specialist to confirm if your car meets the required emission regulations. This assures that your car is suitable for conversion and that you are helping to a cleaner environment.
4. Choose the right conversion kit
There are two main types of CNG conversion kits: Sequential and Venturi kits. Choosing the right one depends on your vehicle’s make, model, and engine type.
- Sequential kits are more advanced and inject CNG directly into the intake manifold. These kits are efficient and work best with newer vehicles that have sophisticated engine management systems.
- Venturi kits are simpler and generally more affordable. They are suitable for older vehicles with simpler engines but may not offer the same level of performance as sequential kits.
If you reside in an urban region and own a newer vehicle with advanced electronics, a sequential kit may be a better option. A Venturi kit might still do the job for people on a tight budget or who own older vehicles.
5. Use a certified conversion centre
Safety and efficiency are critical when converting your vehicle to CNG. It’s important to have the conversion done at a certified centre where trained technicians follow the necessary safety standards. Proper installation ensures your CNG system runs smoothly and reduces the risk of accidents.
Some CNG filling stations also serve as conversion centres, making it convenient to switch and fill up your vehicle in one location. Companies like NIPCO Plc, Bovas, Axxela, and the Nigerian National Petroleum Company (NNPC) Limited have partnered with the PCNGI to provide conversion services across Nigeria.
