Exhaust valves control the flow of gases out of the combustion chamber. They open and close at specific times during the operating cycle, allowing exhaust gases to be expelled from the cylinder, then close to prevent those expelled gases from returning during the compression and combustion phases. Use high-quality fuel to prevent residue buildup and drive smoothly to reduce stress on the valves and exhaust system. The valves are the guardians of the engine, unleashing its potential and allowing you to experience the true freedom of the open road.
