Dual-fuel engines

Definition

Dual-fuel engines are internal combustion engines that can operate on two different types of fuel, typically a combination of gas and a liquid fuel like diesel. This flexibility allows for improved efficiency and reduced emissions, making them suitable for integration with renewable energy systems. By using alternative fuels, these engines can help in transitioning to more sustainable energy sources while maintaining performance and reliability.
