CNG Powertrain

CNG powertrain is a sort of alternative fuel system that runs on natural gas instead of the conventional petrol or diesel used in automobiles. Since there is a worldwide pursuit for more affordable and environmentally friendly energy sources, CNG powertrains have emerged as an appealing option to reduce greenhouse gas emissions and promote sustainable mobility. This technology is increasingly being adopted by various sectors such as corporate fleets, private vehicles and public transport.

Central to a compressed natural gas (CNG) powertrain is an internal combustion engine which has been modified to operate on compressed natural gas similar to gasoline and diesel engines. Compressed natural gas (CNG) is contained under pressure in large steel or composite tanks. Power is generated after fuel from these cylinders is mixed with air in the combustion chamber and ignited. Unlike other fuels, CNG engines have fuel injection and storage systems mainly meant for breathing, but not off the shelf combustibles; this responsible for their major difference!

An internal combustion engine that has been converted to run on compressed natural gas, much like petrol and diesel engines, is the heart of a compressed natural gas (CNG) powertrain. Large steel or composite tanks hold compressed natural gas (CNG) under pressure. Fuel from these cylinders is combined with air in the combustion chamber and ignited to produce power. The primary distinction between CNG engines and other fuels is that the former have fuel injection and storage systems designed primarily for breathing, while the latter are used for off-the-shelf combustibles!

In addition to their environmental and cost benefits, CNG powertrains offer performance advantages. Modern Compressed natural gas engines are designed to deliver similar or even superior performance to traditional fuel engines. They provide good torque, reliability, and efficiency, making them suitable for a range of applications, from passenger cars to heavy-duty trucks. Furthermore, many automakers offer dual-fuel systems that allow vehicles to run on both CNG and gasoline, providing flexibility for drivers in regions where CNG refueling infrastructure is still developing

Another important feature is CNG powertrains that don’t cost much. The prices of gas over time can save a lot on fuel costs since they are usually cheaper than gasoline or diesel. As a result, these vehicles are very attractive to fleet operators (like public transport operators, delivery services and other organizations focused on reducing costs). In addition, natural gas is also abundant which reduces dependence on oil and provides a stable energy source for transportation at large.

Unlike traditional gasoline or diesel engines, a compressed natural gas (CNG) powertrain is an alternative fuel system that uses compressed natural gas as the vehicle's primary energy source. In addition to being cheaper. CNG is increasingly becoming common in various industries like the commercial fleets, public transport and personal cars due to increasing demand for greener energy.
The heart of a CNG power train is a customized internal combustion engine designed to run on natural gas. The fuel is stored in high-pressure tanks and sent into the engine, where it combines with air and ignites to produce power. The system has been designed to manage the unique properties of compressed natural gas just like classic engines do.

The economic advantages of CNG powered vehicles are worth considering too. This is because natural gas is usually cheaper than gasoline or diesel, therefore, reducing the drivers’ fuel expenses (Ganji & Arora, 2019:16). In this case, CNG vehicles tend to appeal more to flees that operate on low profit margins such as delivery services, taxi drivers and bus companies. On the other hand, however, there lie some huddles that hinder the extensive use of CNG engines. The availability of the needed CNG refueling stations is very low in many places hence it becomes difficult to refill one’s car with gas easily. A CNG powered car could also have a higher initial price than a similar conventional vehicle but over longer periods, such savings might account for it (Patel et al., 2018:48-49).
