venttiiliaikaa
Venttiiliaikaa, also known as valve timing, refers to the precise control of the opening and closing of engine valves in an internal combustion engine. This process is crucial for the efficient operation of the engine, as it regulates the intake and exhaust of gases, which in turn affects the engine's power output and fuel efficiency. The timing of the valves is typically controlled by a camshaft, which is driven by the engine's crankshaft via a timing belt or chain.
The valve timing is usually optimized for specific engine operating conditions, such as idle, part-throttle, and
Modern engines often feature variable valve timing (VVT), which allows the valve timing to be adjusted on
