Some important points about CNG gas and its standard usage :

from condensing natural gas ( like ) And a small amount of other gases is obtained.
But the pressure used in CNG tanks is 12,000 times higher than that of a domestic gas stove. For this reason, you should be careful and avoid any manipulation of car tanks separately.

What does tank manipulation mean?

Any type of use of tools and cutting devices in order to increase the size of the tank, welding in order to connect or separate other parts and pieces to the main tank and ……… It is considered tank manipulation .

You should note that even if the tank is empty, it contains a small amount of gas ( Every car gas tank will never be completely empty after the first refueling ) It can explode with the slightest spark or heat caused by the use of cutting and welding tools. Therefore, any installation or disconnection of tank connections, or using tools to adjust valves, or how to release gas and control it, must be done in authorized conversion and repair workshops approved by the National Iranian Petroleum Products Distribution Company..

If there is a change in the appearance of the fuel tank as a result of the impact caused by the accident ( Indentation – changing the appearance of welding and cracking connections…) If you noticed or smelled the smell of gas in the room and around the car, immediately go to a repair shop or an authorized workshop for the installation and repair of CNG tanks and be careful that any action should only be performed by the technicians of authorized workshops for installing tanks. .

Don't forget to follow the order and standard instructions during refueling, it provides safe conditions for you, the passengers and the station staff. .

Note that the use of any device that can create sparks of any kind is prohibited . devices such as cigarettes- Pipes, matches, gas lighters – Gasoline or electric, mobile phones, toys, flashlights, or any device that has a battery .

For this reason and to prevent sparks during the possible and accidental use of these devices, you and other passengers should not be in the danger zone and close to the car when refueling..

Passengers must get out of the car and sit in the passenger area when entering the station . If for any reason the station does not have such a place, the passengers must stand at the exit of the car and outside the station.

After entering the station and settling in the refueling place, the driver must turn off the car, open the trunk, and apply the handbrake. (In automatic transmission cars, put the gear in the park position) and wait in the passenger area or at the exit entrance.

It is also important to pay attention to this point, when entering the gas station, the front of the car should always be facing the exit door, so that in case of emergency exit, this can be done as soon as possible..

And lastly,

The use of station equipment is strictly prohibited for all people, including car drivers, passengers, and miscellaneous people . Refueling should only be done by a trained station operator .

• When refueling at CNG gas stations, the car engine must be turned off.
• Shaking the car while refueling at CNG stations has no effect on increasing the amount of gas entering the tank..
• In case of damage to the car's gas system, it is necessary to immediately refer to authorized workshops for installing CNG tanks; Most of these types of injuries occur in accidents and system manipulation.
• Equipping the car with compressed natural gas system (C. Eng)It should be done in authorized and approved conversion workshops of Iran's National Oil Products Distribution Company.
• Having a valid refueling label is required to use natural gas at stations.
• The use of the nozzle and its connection for refueling the vehicle is allowed only by the station operator (The operator must be a trained person and at the time of entering the vehicle, he must first visit the authorized refueling sticker that is installed on the windshield, and before connecting the nozzle to the vehicle, lift the trunk of the vehicle and, while checking the tank visually, make sure that the tank is not damaged, and avoid servicing by smelling the smell of gas from the trunk of the vehicle in case of leakage.).

Please be careful that everything mentioned during travel and opening and closing the tank or during gas leakage should only be done by the employees of authorized CNG tank installation workshops. .

• For refueling at CNG stations, only the car driver is allowed to enter the refueling station.
• Smoking and using mobile phones are strictly prohibited at gas stations.
• In order to ensure the proper functioning of the equipment installed on the car, it is mandatory to visit the authorized centers for periodic inspection of the dual-fuel car on an annual basis. (By inspecting the gas equipment, the authorized centers, in addition to issuing the refueling label, also issue an insurance policy and deliver it to the car owners.).
• Any cutting, welding or repair of the tank will immediately cause the tank to explode during the first refueling.
• If you see any defects in the gas system of the car, go to authorized conversion workshops or CNG after-sales service centers of car companies as soon as possible..
• Leave the connection of the nozzle to the car and refueling to the station operator and never refuel.
• Respect each other and maintain order in the places by respecting the turn and protecting the rights of others.

Necessary safety tips in the maintenance of dual-fuel vehicles:

• Be careful with the car's electronic systems when washing the car(Emulator, addoner and ECU) Do not spill water.
• To perform any repairs on the system, refer to specialized repair shops.
• Always keep the fuel valve closed by the cap to prevent dust from entering the fuel valve.
• Check the thermostat and be sure to use enough antifreeze in all seasons.
• Leave the connection of the nozzle to the car and refueling to the station operator and never refuel.
• Respect each other and maintain order in the places by respecting the turn and protecting the rights of others.
