The use of CNG can generate fuel savings and increase the profit margin for professional drivers or those who travel long daily distances.
São Paulo, March 2025 - Vehicular natural gas (CNG) It is a fuel in gaseous form that offers several advantages for those who choose to convert it. Among the main benefits, destacam-se a economia de 30% a 40% em relação aos combustíveis convencionais e a redução das emissões de CO₂.
These characteristics make CNG an attractive alternative, especially for professional drivers, as taxi drivers, App drivers and delivery car operators. A NGK, Niterra brand specialized in components for ignition systems, highlights some care and adaptations necessary for conversion.
Storage cylinder – Natural gas is stored in a specific cylinder, usually installed in the trunk, reducing the car's load capacity.
Management and Feeding Kit – The system must be compatible with the vehicle model for proper engine operation.
Regularization of the conversion – After installation, the issuance of the Vehicle Safety Certificate is mandatory (CSV), in addition to updating the car document to include the conversion.
Specific maintenance – the CNG system requires periodic inspections to ensure the proper functioning and safety of the transport.
Impact on ignition components – the use of CNG can reduce the useful life of spark plugs, Ignition Cables & Coils, making it essential to adopt high-quality components and reduce recommended maintenance intervals.
Re-certification of the cylinder – as required by law, The cylinder must undergo periodic inspections to ensure its integrity and safety.
Attention to the ignition system
NGK warns that vehicles converted to CNG may require more frequent maintenance on the ignition system, because this type of fuel requires a higher voltage for the spark plugs.
"After the installation of the CNG kit, It is essential to maintain regular maintenance of the car and the kit", afirma Hiromori Mori, Niterra Technical Assistance Consultant. "The installation must be regularized, and heavy use requires anticipation of maintenance. Gas makes it difficult for candles to spark, making it necessary to change spark plugs more frequently, cables and coils. The air filter should be checked, and the extra weight of the kit impacts brakes, Suspension and tires, demanding attention."
Niterra reinforces that the installation of the CNG kit represents a modification to the original project. That is why, in addition to ensuring that the conversion is in compliance with the standards and properly regularized, it is essential to maintain periodic maintenance of both the vehicle and the CNG system itself.
