What Is A Dizzy On A Car? Understanding the Role

Have you heard the word dizzy on a car? If you ever come across this specific word and don’t know What Is A Dizzy On A Car?

Well, the word dizzy is used to identify a car’s distributor. A distributor’s job is to send high-voltage current via spark plugs to ignite the engine. Which means it helps your car to start.

In this blog post, we will discuss about dizzy and its importance and its usage in your car.

What is a dizzy?

The distributor in a car engine, sometimes called “dizzy” for short, is an important part of the ignition system. Its job is to send a spark of electricity to the spark plugs in the right order so that the fuel and air mixture in the engine’s cylinders can ignite and power the car.

In short, traditionally seen in older cars, the distributor is a mechanical component that serves as a switch to distribute high-voltage electrical current from the ignition coil to the spark plugs in the correct firing order.

Opening and closing at specific times ensures that the current is sent to the appropriate spark plug, Which enables the engine to operate smoothly and efficiently.

The dizzy is typically mounted on the engine’s cylinder head or block and is driven by a gear on the camshaft. There are several vital components in a dizzy or distributor which help it to function properly, such as:

Rotor: The rotor is a really important part of your car’s engine. It spins around a central point and is located inside a cap. 

As the central point, called the dizzy shaft, turns, the rotor moves past different contact points inside the cap. This movement allows electricity to flow to the right spark plug at the right time. Without the rotor, your car’s engine wouldn’t be able to run properly!

Cap: The dizzy cap is a cover made of either plastic or metal that sits on top of the distributor. It houses both the rotor and contact points, and it also serves to insulate electrical current, preventing any leaks.

Contact points: The contact points are little metal tabs hanging out in the distributor cap that connects with the rotor as it spins around. When the rotor comes close to a contact point, it zaps a jolt of strong electric power to the correct spark plug.

Condenser: The condenser is a small electrical component in the distributor that is located near the contact points. Its works as a reducer of electrical arcing that occurs when contact points open and close.

Distributor shaft: A distributor shaft is a long metal rod that runs through the center of the distributor and connects the rotor to the engine’s camshaft. When the camshaft rotates, it turns the shaft, and in turn, it makes the rotor rotate too.

Types of dizzies

Many distributors have been utilized throughout the evolution of cars. each one possesses unique benefits and drawbacks. Here are some of the types of distributors found in cars throughout history: 

1. Points and Condenser Distributor:

This type of distributor is the oldest and most basic type of distributor. It uses points and a condenser to open and close the circuit and produce a spark. 

Points and condenser distributors are simple and reliable, but they require regular maintenance to keep the points and condenser clean and to function correctly.

2. Electronic Distributor:

An electronic distributor uses an electronic ignition module to replace the points and condenser, making it more reliable and maintenance-free than a points and condenser distributor. 

Electronic distributors are also more efficient, producing a stronger spark and improving fuel economy and performance.

3. High-Energy Distributor:

A high-energy distributor uses an ignition coil that produces a higher voltage spark than a standard distributor. 

It improves the performance and efficiency of the engine. High-energy distributors are typically found in high-performance cars or vehicles with modified engines.

4. Coil-on-Plug (COP) Distributor:

A Coil-on-Plug (COP) distributor functions similarly to a DIS (Distributorless Ignition System) but employs individual ignition coils placed directly on each spark plug. 

By using separate coils for each plug, COP systems generate more powerful and accurate sparks, resulting in enhanced performance and efficiency.

How do the dizzy Works

How does a distributor or dizzy work?

The distributor is a crucial component of your car’s ignition system. It acts as the control unit behind your engine, controlling the flow of electricity from the ignition coil to the correct spark plug at the perfect moment. 

This spark ignites the fuel and air mixture in your engine’s cylinders, creating the power that propels your car forward.

The distributor consists of several parts, including a rotor and distributor cap, all of which are installed in a housing attached to your engine block. As your engine rotates, the distributor rotor spins and sends the electrical current down the appropriate spark plug wire in the correct sequence.

Even though modern cars use electronic ignition systems, distributors are still necessary for many vehicles. 

It’s also important to keep your distributor in excellent condition by regularly inspecting and servicing it by a qualified mechanic. This will help your engine run smoothly and keep your car performing at its best.


As we mentioned above, dizzy means a distributor of a car.

A distributor is important in a car’s engine because it distributes high voltage electrical current to the spark plugs, ensuring they fire at the right time and sequence. Without it, the engine may misfire or not start at all. It also affects the performance, fuel efficiency, and emissions of an engine.

In modern cars, distributors have been largely replaced by electronic ignition systems that use sensors and electronic control modules to precisely time the spark. 

However, some older vehicles still relies on distributors to operate. 

Either way, the distributor plays a huge role in the proper functioning of an engine for performance and reliability on top of Form.
