How the duel fuel engines work?

Duel fuel engines operate using two different types of fuel, typically a combination of natural gas and diesel or heavy fuel oil. During operation, the engine primarily runs on gas, while a small amount of diesel is injected to ensure proper ignition and combustion, especially during starting and under heavy load conditions. This setup allows for enhanced fuel efficiency and reduced emissions, as natural gas generally burns cleaner than diesel. The engine can switch between fuels based on availability or operational requirements, providing flexibility and efficiency.
