Many auto manufacturers have already eliminated them as parts of the vehicle they manufacture. Some vehicle owners would despise them because their early deterioration would usually cause some mysterious problems. But if you own an Acura that is still equipped with a point type ignition system, you've got no other choice but to take care of them. We're talking here about the Acura distributor—the central component of point type Acura ignition systems.
Distributors are ignition system components used on almost all classic and vintage vehicles and some late model vehicles. In particular, distributors are used on vehicles still using the point-type ignition systems. New vehicles rarely use this type of ignition system. Instead, modern vehicles make use of the distributor-less or electronic ignition system.
Acura distributors perform two basic functions: (1) to distribute high voltage pulses to the engine's spark plugs in the proper firing order, and (2) to trigger the high voltage pulses coming from the ignition coil. The first function is basically performed by the distributor rotor and the distributor cap. The rotor is a rotating arm, driven by the engine camshaft, that is connected to the ignition coil. The distributor cap, on the other hand, is a cap that houses the contacts for the spark plugs. As the rotor rotates underneath the distributor cap, it distributes the high voltage pulses from the ignition coil to the individual spark plugs in the correct firing order.
The second function of the distributor is basically performed by the breaker points, cam follower, distributor cam and condenser, all of which are housed in the bottom half of the distributor. These components perform the job of breaking the current to the coil, thus triggering the coil to release high voltage pulses.
Because Acura distributors are mechanical components, their various parts are easily susceptible to wear and tear. The arcing of voltage pulses from the rotor tip to the spark plug contacts would also cause the distributor cap and rotor to deteriorate early. This is probably the reason why many auto manufacturers now avoid the use of distributors. But if your Acura is equipped with one, you've got no choice but to take good care of them. You must also replace the Acura distributor cap or the Acura distributor rotor each time it gets damaged. You don't need to worry much, though, because Parts Train is online 24 hours to provide you with all the Acura distributor parts that you need.
