A camless engine is an innovative type of internal combustion engine that eliminates the traditional camshaft, which controls the timing of the engine's valves. Instead, it uses advanced technologies like electromechanical actuators or hydraulic systems to adjust valve timing and lift dynamically. This allows for more precise control over the engine's performance, improving efficiency and power output. By removing the camshaft, camless engines can adapt to different driving conditions in real-time, optimizing fuel consumption and reducing emissions. This technology has the potential to enhance the overall performance of vehicles, making them more environmentally friendly while maintaining power and responsiveness.
