Q.6. What is ‘S-CNG’? Describe its different uses.

‘S-CNG’ stands for Sequential Compressed Natural Gas. It is a technology used in automotive vehicles to optimize the combustion of compressed natural gas (CNG). This technology is equipped with an intelligent injection system and dual interdependent ECUs (Engine Control Units) to ensure an optimum air-fuel ratio during combustion. The system allows for better and more consistent performance along with high fuel efficiency across various driving conditions.

The different uses of S-CNG technology include:

• Automotive Fuel: S-CNG is primarily used as a fuel for transport vehicles such as cars and buses. It is an alternative to traditional fuels like petrol and diesel, offering a cleaner and more eco-friendly option.
• Enhanced Performance: Vehicles equipped with S-CNG technology are designed to deliver improved performance and enhanced drivability across different terrains.
• Safety Features: S-CNG vehicles come with safety features like corrosion-resistant stainless steel pipes and joints, integrated wiring harnesses to eliminate short circuits, and micro switches that ensure the vehicle does not start during the CNG fuel filling process.
• Convenience: The technology includes an auto-switch feature that allows drivers to easily switch between CNG and petrol, providing uninterrupted driving experience even when CNG is not available.
• Fuel Efficiency: S-CNG vehicles are known for their fuel efficiency, which can lead to cost savings over time compared to conventional fuel vehicles.

Overall, S-CNG technology represents a significant advancement in green fuel mobility, setting new benchmarks for performance, safety, and convenience in CNG vehicles.
