Best Time to Refill CNG in Car: Frequent visits to the fuel pump is a major hassle for CNG car drivers. Smaller cylinder and tank means the vehicle covers less distance and requires frequent gas refills. Especially in small towns where CNG stations are few, standing in long queues of vehicles is a waste of time for drivers. If you also think that CNG delivery at any time of the day makes no difference, then this report will be very useful for you.
Why is it better to pump CNG early in the morning or late at night?
According to experts, it is more beneficial to pump CNG early in the morning or late at night, as the ambient temperature is relatively low at this time. Gas remains more dense due to lower temperature. As a result, the cylinder can hold more gas. Morning is considered to be the best time for refueling at CNG stations as the temperature is lower before sunrise. Similarly, the density of CNG is likely to increase as the temperature drops late at night after being hot throughout the day.
The biggest game of pressure in proving gas
The real game when filling CNG is pressure. The higher the pressure, the more gas will fill the cylinder and its direct benefit will be seen in the mileage of the vehicle.
According to Indian Oil, CNG is stored in vehicles at a high pressure of around 200 kg/cm². It is very important to have proper pressure at the CNG pump to fill the cylinder completely. When several vehicles are continuously refueling at the pump, the station’s pressure may drop. So going to the pump at less crowded times gives more pressure.
Stations connected to pipelines more advantageous
Gas supply and pressure remains more stable at CNG stations connected to pipelines and having excellent compressor systems. According to IGL, the CNG cylinder is designed to withstand high pressure and also features a ‘safety burst disc’ for protection.
So if you have the option, getting CNG early in the morning or late at night – when the temperature is lower and the pumps are less crowded – is the best option.
