poppetconstructie
Poppet construction is a type of internal combustion engine design where the intake and exhaust valves are operated by a poppet valve mechanism. This mechanism consists of a valve stem, a valve head, and a valve spring. The valve stem is connected to the valve head, which is held in place by the valve spring. When the engine's camshaft rotates, it pushes the valve stem up and down, opening and closing the intake and exhaust valves.
Poppet construction is commonly used in gasoline engines, particularly in cars and motorcycles. It is favored
In recent years, there has been a trend towards using poppetless valve mechanisms, such as overhead camshafts
