süütejuhtmed

Süütejuhtmed, also known as spark plug wires or high tension leads, are essential components of an 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 pulse is what ignites the fuel-air mixture within the engine's cylinders, causing combustion and generating power.

Each cylinder in an engine typically requires its own süütejuhe, connecting the coil (or a distributor) to the spark plug located in the cylinder head. These wires are designed to withstand the extreme temperatures, vibrations, and electrical interference present within the engine compartment. They are typically made of a conductive core, often copper or a resistive material to suppress radio frequency interference, surrounded by layers of insulating material like silicone or rubber.

Over time, süütejuhtmed can degrade due to age, heat, and exposure to engine fluids. Symptoms of faulty süütejuhtmed can include engine misfires, rough idling, a decrease in power, poor fuel economy, and difficulty starting the engine. Visually inspecting them for cracks, brittleness, or signs of corrosion can help identify problems. Replacing worn-out süütejuhtmed is a relatively straightforward maintenance task that can significantly improve engine performance and efficiency.
