Definition: S.CNG stands for Suction-Cooled Compressed Natural Gas. It is a type of compressed natural gas (CNG) used in automobile engines. Unlike traditional CNG, S.CNG is cooled before entering the engine, enhancing its performance and efficiency.
Uses:
1. Automotive Fuel: S.CNG is primarily used as a cleaner alternative to petrol and diesel in vehicles, reducing emissions of nitrogen oxides and particulate matter. It improves fuel efficiency and lowers running costs.
2. Power Generation: It can be used in stationary engines for power generation, providing a more environmentally friendly option compared to coal or diesel.
3. Industrial Applications: S.CNG is utilized in industrial processes where clean fuel is required, contributing to reduced air pollution and lower operational costs.
Recent examples include the implementation of S.CNG in public transport systems in cities like Delhi and Mumbai, which aim to curb urban air pollution and promote sustainable transportation solutions.
In summary, S.CNG offers environmental benefits and economic advantages across various applications, supporting cleaner and more efficient energy use.
