How does a dual-fuel system function?

A dual-fuel system is designed to enable an engine to operate on two different types of fuel, such as gasoline and compressed natural gas (CNG). This flexibility in fuel choice allows for increased efficiency and adaptability in various driving conditions or when one fuel type might be less available or more expensive. By optimizing the fuel source based on the conditions, dual-fuel systems can enhance performance and reduce emissions, making them a viable option for meeting diverse fuel needs while also contributing to sustainability efforts.

This system typically involves modifications to the engine and fuel delivery systems to ensure optimal performance and combustion of both fuel types. Consequently, drivers can experience a seamless transition between fuels, which can be beneficial in terms of range and operational cost.

In contrast, operating exclusively on gasoline, using separate engines for different fuels, or replacing gasoline with electricity does not accurately describe the concept of a dual-fuel system, which is centered on the ability to utilize two fuel types interchangeably.
