Don't Use Unauthorized CNG Kits

It is always recommended to purchase a factory-fitted CNG vehicle because they are well-built and have passed all of the required compliances. However, many individuals convert their conventional automobiles to CNG vehicles by having an unlawful CNG kit installed by a local technician. Because the automobile has not been proven to be a CNG vehicle, the installation of unauthorised kits by a local mechanic might result in leakage or damage to the mechanicals of the car. When it comes to CNG kit installation, stay away from local mechanics.

Prefer Sequential CNG Kits 

All of the new technology sensors and the ECU are included in the sequential CNG kit. The gas injectors are connected to the intake manifold's existing fuel injectors. CNG flow is monitored and modified electrically by a separate ECU, similar to how petrol flow is controlled by the ECU. The availability of sensors and the ECU is the key difference between the normal and sequential CNG kits. 

Use CNG Compatible Spark Plugs

Since they are responsible for fuel combustion, spark plugs are one of the most crucial components of an engine. Make sure you replace your spark plugs with CNG-compatible ones when installing a CNG kit. If you can't find CNG-compatible spark plugs, you'll have to narrow the distance between the spark source and the spark plug's metal tip.

Check For Leakage on Regular Intervals

A CNG car owner must inspect the CNG fuel cylinder for leaks on a regular basis. Gas leakage caused by improper kit installation or overfilling the cylinder might result in a fire or cylinder explosion. It is preferable to have the cylinder checked for any signs of leaking, and if any signs of leakage are found, take your automobile to the local service centre to have it repaired.

Keep An Eye on CNG Tank Pressure

When refilling CNG, make sure the cylinder pressure does not exceed the manufacturer's recommended pressure. Overfilling the cylinder might result in leaks, which pose a significant danger of fire. The pressure may be measured using the gauge on the refilling machine.

While Refueling, Turn Off the Ignition

When refilling your CNG tank, turn off your car's ignition. Letting the car's engine running might result in dangerous situations due to the possibility of fire. CNG can be ignited by a small spark, thus it's best to turn off the ignition to be safe.

Always Start on Petrol Mode

Always start a CNG car in petrol mode and leave it there until the engine has warmed up. After the engine has achieved its ideal working temperature, you can switch to CNG mode, which results in extended engine life owing to appropriate lubrication before converting to CNG fuel.

Avoid Substandard Accessories

When installing a CNG kit, avoid choosing low-quality parts. Check to see if the cylinder and fuel lines are of good quality and made according to industry requirements. Ensure the CNG kit you purchase is compatible with your vehicle. If the kit is incompatible with the automobile or of poor quality, there is a great risk of fire or damage to the car's components.

Avoid Smoking in Car

It is not permitted to smoke in a CNG car. Smoking in the car is dangerous since it can spark a fire, and with a CNG cylinder in the back, the consequences might be fatal.

Get Your CNG Kit and Cylinder Tested

Following the installation of a CNG kit in your vehicle, you must get a CNG Cylinder Test Certificate from an authorised CNG Kit dealer. The certificate is crucial since it will serve as documentation that you have installed a branded and certified CNG kit and cylinder in your car. All cars that operate on CNG must have their cylinders checked for hydro once every three years.

Keep a Fire Extinguisher Handy

All company-fitted CNG cars are equipped with a fire extinguisher, which is placed in a location that might be easily accessible in the event of a fire. It is required for CNG cars to have a fire extinguisher, so if you are getting your car installed with an aftermarket CNG kit, make sure you have one as well.

So that was all about the CNG maintenance tips, to keep your CNG vehicle safe. Maruti Suzuki WagonR, Maruti Celerio, Hyundai Grand i10 Nios, and Tata Tiago i-CNG are some of the CNG vehicles offered in India that come with company-fitted CNG kit.
