👉 Exhaustless, also known as "exhaust-free," is a concept in automotive engineering that refers to an engine or vehicle that does not emit any pollutants from its exhaust system. This eliminates the need for an external exhaust system, making it easier and safer to drive. Exhaustless engines are designed to be clean and efficient, with no emissions from the combustion chamber. Exhaustless vehicles typically have a lower fuel efficiency due to their smaller size, but they are generally more fuel-efficient than traditional
