Valves in the engine are crucial for controlling the gas exchange by regulating the inlet of the fuel-air mixture and the outlet of the exhaust gases. Intake valves open to allow the mixture into the cylinder, while exhaust valves expel the burnt gases.
These valves work in synchronisation with the crankshaft and are controlled by the camshaft. The precision and timing of valve opening and closing are critical to engine performance and efficiency.
Regular adjustment and maintenance of the valves are necessary to ensure optimum performance and smooth operation.
High-quality materials and technologies, such as titanium valves and variable valve timing, improve the durability and performance of modern motorbike engines.
