What feature is essential in a dual-fuel engine system operating on LPG and gasoline?

In a dual-fuel engine system that operates on both LPG and gasoline, a switchable fuel management system is vital. This system is designed to seamlessly transition between fuel types, ensuring optimal performance depending on conditions like availability, temperature, and emissions requirements.

A switchable fuel management system controls how the engine consumes fuel and adjusts various parameters such as fuel injection timing and mixtures for each fuel type. This adaptability enhances efficiency and allows for smoother operation, as the engine can respond to changes in fuel quality and engine load.

While other features might provide support or convenience, only a switchable fuel management system directly impacts the engine's ability to operate effectively on both LPG and gasoline, making it an essential component of a dual-fuel engine.
