käivitusmeetod

Käivitusmeetod refers to the method by which an engine or motor is started. This term is commonly used in the context of internal combustion engines, electric motors, and even some mechanical systems. The primary goal of any käivitusmeetod is to initiate rotational motion in the engine or motor, enabling it to begin its normal operating cycle.

For internal combustion engines, the most prevalent käivitusmeetod involves an electric starter motor. This starter motor, powered by the vehicle's battery, engages with the engine's flywheel or crankshaft, providing the initial torque required to turn the engine over. This cranking action draws in fuel and air, compresses the mixture, and eventually ignites it, leading to self-sustained combustion. Older vehicles might have used a manual crank for starting, but this method is largely obsolete due to safety and convenience reasons.

In electric motors, the käivitusmeetod can vary significantly depending on the motor type and application. Simple DC motors might start directly when power is applied. More complex AC motors, such as induction motors, often employ specific starting circuits to limit inrush current and provide adequate starting torque. These can include direct-on-line starters, star-delta starters, or soft starters, each offering different levels of control and protection. The choice of käivitusmeetod for an electric motor is crucial for its longevity and efficient operation.
