How Does an Electric Choke Work?
Have you ever wondered how your car’s choke works? If so, you’re not alone. Many people are curious about this simple but important device. In this article, we’ll take a closer look at how an electric choke works and how it helps your car start.
What is an Electric Choke?
An electric choke is a device that is used to enrich the air-fuel mixture in a car’s carburetor. This enrichment is necessary when the engine is cold, because a cold engine needs more fuel to start than a warm engine.
The electric choke is controlled by a thermostat. When the engine is cold, the thermostat closes a switch that activates the choke. This causes the choke plate to close, which restricts the amount of air that flows into the carburetor. This enrichment of the air-fuel mixture helps the engine start more easily.
How Does an Electric Choke Work?
The electric choke works by using a bimetallic strip. This strip is made of two different metals that expand at different rates when they are heated. When the engine is cold, the bimetallic strip is cool and it bends. This causes the choke plate to close.
As the engine warms up, the bimetallic strip heats up and it bends the other way. This causes the choke plate to open, which allows more air to flow into the carburetor.
The electric choke is a simple but effective device that helps your car start more easily. It is a vital part of your car’s carburetor, and it is important to make sure that it is working properly.

An electric choke is a device that is used to control the amount of air that flows into an engine. It is typically used on engines that are cold, as it helps to warm up the engine more quickly. Electric chokes are typically controlled by a thermostat, which senses the temperature of the engine and activates the choke when the engine is cold.
The Basics of an Electric Choke
An electric choke consists of a number of components, including:
- A choke plate: This is a plate that is located in the intake manifold and controls the amount of air that flows into the engine.
- A choke cable: This cable connects the choke plate to the thermostat.
- A choke thermostat: This thermostat senses the temperature of the engine and activates the choke when the engine is cold.
How an Electric Choke Works
When the engine is cold, the thermostat closes the choke, which restricts the amount of air that flows into the engine. This causes the engine to run more slowly and with a richer fuel mixture, which helps to warm up the engine more quickly.
As the engine warms up, the thermostat opens the choke, which allows more air to flow into the engine. This causes the engine to run faster and with a leaner fuel mixture, which is more efficient.
Advantages and Disadvantages of Electric Chokes
Electric chokes have a number of advantages over mechanical chokes, including:
- They are more precise, as they are controlled by a thermostat.
- They are easier to use, as they do not require the driver to manually adjust the choke.
- They are more reliable, as they are less likely to fail than mechanical chokes.
However, electric chokes also have a number of disadvantages, including:
- They can be more expensive than mechanical chokes.
- They can be more difficult to troubleshoot, as they have more components than mechanical chokes.
- They can be more susceptible to damage from electrical problems.
Electric chokes are a valuable tool for helping to warm up engines more quickly. They are more precise, easier to use, and more reliable than mechanical chokes. However, they can be more expensive and more difficult to troubleshoot.
Additional Information
- Electric chokes are typically used on gasoline engines. Diesel engines do not use chokes, as they do not need to be warmed up before they can start.
- Electric chokes are typically used on engines that are less than 4 liters in displacement. Larger engines typically use a different type of choke, called a manual choke.
- Electric chokes are typically used on engines that are equipped with a carburetor. Engines that are equipped with fuel injection do not use chokes.

How Does Electric Choke Work?
An electric choke is a device that is used to control the amount of air that is allowed to enter the carburetor of a gasoline engine. It is used to help the engine start more easily when it is cold.
Electric chokes work by using a thermostat to control the amount of current that is flowing to the choke. When the engine is cold, the thermostat closes, which causes the choke to open. This allows more air to enter the carburetor, which helps the engine to start. As the engine warms up, the thermostat opens, which causes the choke to close. This reduces the amount of air that is allowed to enter the carburetor, which helps to improve the engine’s performance.
Electric chokes are typically used on gasoline engines that are equipped with a carburetor. They are not used on engines that are equipped with fuel injection systems.

Troubleshooting Electric Chokes
If an electric choke is not working properly, there are a number of things that can be checked:
- Check the wiring to the choke.
- Check the thermostat to make sure it is working properly.
- Check the choke itself to make sure it is not stuck.
If the choke is still not working properly, it may need to be replaced.
Electric chokes are a valuable tool for helping gasoline engines start more easily when they are cold. They are relatively easy to use and maintain, and they can help to improve the performance of your engine.
If you are experiencing problems with your electric choke, it is important to have it properly diagnosed and repaired. A malfunctioning choke can cause your engine to run poorly or not start at all.
How does an electric choke work?
An electric choke is a device that is used to control the amount of air that flows into a carburetor. It is typically used on gasoline engines that are cold-started. When the engine is cold, the air-fuel mixture needs to be richer in order to start properly. The electric choke helps to provide this richer mixture by restricting the amount of air that flows into the carburetor. As the engine warms up, the choke is gradually opened, allowing more air to flow into the carburetor and providing a leaner air-fuel mixture.
What are the different types of electric chokes?
There are two main types of electric chokes:
- Diaphragm chokes use a diaphragm to control the choke valve. The diaphragm is connected to a bimetallic spring, which is heated by the engine’s coolant. As the coolant warms up, the bimetallic spring bends, which causes the diaphragm to move and open the choke valve.
- Solenoid chokes use a solenoid to control the choke valve. The solenoid is energized by the engine’s ignition switch, which causes the choke valve to open.
How do I adjust an electric choke?
The choke should be adjusted so that it is fully closed when the engine is cold and fully open when the engine is warm. To adjust the choke, you will need to find the choke adjustment screw. This screw is typically located on the side of the carburetor. Turn the screw clockwise to close the choke and counterclockwise to open it.
What are the common problems with electric chokes?
The most common problem with electric chokes is that they stick open or closed. This can cause the engine to run poorly or not start at all. Other common problems include the choke not working at all or the choke valve leaking.
How can I fix a stuck electric choke?
If the choke is stuck open, you can try to free it by spraying some carburetor cleaner into the choke housing. If this does not work, you may need to remove the choke and clean it or replace it. If the choke is stuck closed, you will need to remove it and clean it or replace it.
Can I drive my car with a stuck electric choke?
It is not safe to drive your car with a stuck electric choke. If the choke is stuck open, the engine will run too rich and may overheat. If the choke is stuck closed, the engine will not start or will run poorly. If you suspect that your choke is stuck, you should have it repaired or replaced as soon as possible.
an electric choke is a device that is used to enrich the air-fuel mixture in a carburetor. It is typically used on engines that are cold, as the richer mixture helps to start the engine more easily. The choke is controlled by a cable that is connected to the throttle. When the choke is engaged, it closes off the air intake, which causes the fuel mixture to become richer. As the engine warms up, the choke is gradually disengaged, which allows the air-fuel mixture to return to normal. Electric chokes are a common feature on many small engines, such as those found in lawnmowers, chainsaws, and other outdoor power equipment.
