Cummins diesel engines are a popular choice for several reasons. They are known for their power and durability, and they can be found in various applications.

One question that often comes up is whether Cummins diesel engines have glow plugs. Well, let’s not dribble around.

Here is the direct answer.

Cummins diesel engines do not have glow plugs.

One of the reasons why Cummins engines don’t need glow plugs is because they are designed to start in cold weather conditions.

Cummins diesel engines don’t need glow plugs for a few reasons.

If you still want to know more about the few reasons why Cummins engines don’t use a glow plug, this article will explore that question and provide an answer that will amaze you.

So let us begin.

What Is A Cummins Engine?

Cummins Engine

Cummins is one of the world’s leading manufacturers of diesel engines. The company was established in 1919, and they have headquartered in Columbus, Indiana, United States.

Cummins was designed by a global power leader. They are known for  manufacturing, sells, and services diesel engines and connected technology worldwide.

Cummins engines are found in various applications, including trucks, buses, boats, construction equipment, and agricultural equipment.

The company also provides a wide range of power generation products, including generators and fuel systems.

Cummins engines are known for their power and durability.

They are available in various configurations and can be customized to meet the customers’ specific needs. They also offer a wide range of after-market products and services to support their engines.

What Is A Glow Plug?

Glow Plug

A glow plug is a heating device used to start internal combustion engines. Glow plugs are used in diesel engines and some gasoline engines.

They are typically used in cold weather conditions or when the engine has been idle. Glow plugs are placed in the cylinder head and heat the air in the combustion chamber.

This heated air helps start the engine by igniting the fuel and air mixture.

Why Don’t Cummins Engines Need Glow Plugs?

Now that you know more about Cummins engines let’s explore why they don’t need glow plugs.

As mentioned earlier, Cummins engines are known for their power and durability. They are built to withstand a lot of wear and tear.

One of the reasons why Cummins engines don’t need glow plugs is because they are designed to start in cold weather conditions.

Cummins engines are built with several features that allow them to start in cold weather, including:

  • A block heater that warms the engine block
  • A battery blanket that keeps the battery warm
  • An oil pan heater that keeps the oil warm
  • A thermostat bypass valve that allows coolant to circulate even when the engine is cold

These features enable Cummins engines to start in temperatures as low as -40 degrees Fahrenheit.

Another reason why Cummins engines don’t need glow plugs is that they use high-pressure fuel injection.

This type of fuel injection allows the fuel to be injected directly into the cylinder, where the piston compresses it.

The high pressure of the injection makes sure that the fuel is evenly distributed in the cylinder and that it is fully combusted.

This makes for a more efficient combustion process and eliminates the need for glow plugs.

Cummins engines are also equipped with a pre-heat cycle(heat grid) that runs before starting.

This cycle warms up the cylinders and helps to vaporize any condensation that might be present.

This helps to ensure that the engine is started with dry cylinders, eliminating the need for glow plugs.

So, there you have it. Cummins engines don’t need glow plugs because they are designed to start in cold weather conditions and use high-pressure fuel injection.

Lastly, diesel fuel is less volatile than gasoline, so that it can be injected directly into the cylinder without pre-mixing.

This makes diesel engines more efficient than petrol engines.
