Natural Gas Engines (also known as gas engines) are internal combustion engines that run on natural gas as a fuel source. Commonly used in power generation, transportation, and industrial applications, these engines offer cleaner emissions compared to diesel or gasoline engines. Natural gas engines are known for their fuel efficiency, reduced environmental impact, and cost-effectiveness, making them ideal for sustainable energy solutions.
