süütejuhtmete

Süütejuhtmed, also known as spark plug wires or high-tension leads, are an essential component of a gasoline internal combustion engine's ignition system. Their primary function is to transmit the high voltage electrical current generated by the ignition coil to the spark plugs. This high voltage creates a spark within the spark plug's electrodes, igniting the air-fuel mixture in the combustion chamber.

Each cylinder in an engine requires a dedicated süütejuhtme. These wires are designed to withstand the high voltages and temperatures present in the engine bay. They are typically constructed with a conductive core, insulation material, and an outer protective jacket. The conductive core can be made of various materials, including carbon, copper, or fiberglass, each offering different resistance and durability characteristics. The insulation is crucial for preventing voltage leakage and ensuring that the energy reaches the spark plug effectively.

Over time, süütejuhtmed can degrade due to heat, vibration, and exposure to engine fluids. Common signs of failing süütejuhtmed include misfires, rough idling, poor acceleration, and a decrease in fuel economy. Damaged or worn wires can lead to incomplete combustion, increased emissions, and potential damage to other engine components like the catalytic converter. Regular inspection and replacement of süütejuhtmed are recommended as part of routine engine maintenance to ensure optimal performance and reliability.
