0221604067 Bosch Ignition Coil

An Ignition Coil is a critical part that produces the high voltage necessary for spark creation within an internal combustion engine's ignition system. It is commonly employed in vehicles equipped with gasoline engines, serving as a vital component to ensure efficient fuel combustion and optimal engine performance. The Bosch Ignition Coil (0221604067) measures 230.0 x 84.0 x 104.0 mm and originates from Slovenia. Dimensions are provided by the supplier and may include packaging dimensions. Ignition coils are inductive components transforming low-voltage primary circuit electricity into the high-voltage pulses needed to create an arc at the spark plug gap. These coils are integral to both distributor-based and distributorless ignition systems, commonly located near the spark plugs or within the engine control module housing. Modern designs utilize primary and secondary windings with specific resistance values to achieve required dwell and output voltages. Coil construction varies, employing materials like ferrite or oil-filled casings for thermal management and dielectric strength. Failure modes typically involve open or shorted windings, leading to misfires or no-start conditions, and are diagnosed via resistance measurements and visual inspection for cracking or arcing.
