Quality Distributor Caps for a Better Performing Ignition System

By: Anthony Fontanelle

The ignition system takes charge in delivering perfect timely burning of the fuel mixture within the engine. According to most car experts, it is in the ignition system wherein everything comes together. It is operated with the use of a lock switch, a key, and a code patch.

The ignition system of an engine has a device called the "distributor." It is tasked to effectively divert the high amount of voltage from the ignition coil to the spark plug with precise firing sequence. To perform this function, the distributor needs the help of the and the rotor.

The distributor cap, in particular, is made of durable plastic and a small quantity of copper. Inside the distributor cap lies the distributor rotor which spins upon receiving current from the ignition coils. This current is then transferred to the part of the cap that is made of copper which, in turn, passes the current to the spark plugs. On the other hand, the distributor rotor consists of a metal component that attaches the rotor to the cables of the spark plugs. The distributor cap and distributor rotor work together to deliver to the engine the needed amount of voltage.

Since the distributor cap is constantly subjected to high voltage, it is therefore a must to inspect it regularly for any signs of damage. One must ensure that the sparks are not arcing from point to point within the distributor cap. Moreover, the interior of the cap must be kept clean at all times, making sure that the firing points are free from abrasions or corrosions. Failure to do so may cause the cap to develop carbon cracking that can result to engine misfires. It is, however, important to remember that one must not touch the distributor cap during inspections because it has 20,000 volts running through it. Together with the distributor rotor, the distributor cap must be replaced every 15, 000 miles or every two years for a more efficient performance.
