6.7 Cummins Cooling System Diagram, Specifications and Features

6.7 Cummins cooling system diagram illustrates how the cooling system of a Cummins engine works. The cooling system of Cummins is being mentioned here.

It is an American multinational company with a great name in machines, filter systems, and power products.

The key features of Cummins products are a modest size, not heavy, consuming moderate fuel, muscular potential, and being easy to use.

The features like security alarm and automatic parking are installed in case of any emergency like excessive heat in the exhilarating system, uncontrolled speed, less fuel availability etc.

Detailed Description of 6.7 Cummins Cooling System Diagram

The diagram of the Cummins cooling system depicts the various parts of the cooling system.

The significant factors are the radiator, strain for water, water passage barrel, barrel belfry water transition, outlet channel for Cummins water, Cummins temperature regulator, water permeate, oil cooler, Cummins aftercooler, waft squeezer, injectors,  water pump, and damp drain duct.

The detailed function of the parts of the cooling system is noted below.

01. Radiator

The radiator consists of a strap duct made of copper, a water cooling pipe and is controlled by a DC motor.

It helps in the reduction of air opposition and also widens the heat diffusion area to cool the engine.

The price of the radiator varies from 20 dollars to 100 dollars depending upon the quality of the products.

02. Temperature Regulator

As the name suggests, its function is to balance the temperature of fuel circulation in the engine. It regulates the thermostat in the machine.

If there is no thermoregulator, there will be a rapid elevation in the temperature in the engine. Its price varies from $140 and $300. In the market, various temperature regulators are found.

But the cheap quality temperature regulators often cause the burst of the cooling engine.

04. Waft Squeezer

The waft squeezer is a device that helps extract excessive volumes of air inside the regulatory machine. It constricts the air and regulates the pressure inside the cooling system.

As the engine’s temperature is dropped, the air pressure is dropped and vice versa. To increase the pressure, the waft squeezer is needed.

The price of this part ranges from $200 and $400.

05. After Cooler

The primary purpose of the installation of the aftercooler is to cool the compressed air. The air is compressed by the waft squeezer installed in the cooling engine.

It enables the entrance of more air to increase the rate at which the fuel is combusted. The aftercooler is also known as the turbocharger or supercharger in some systems.

In the market, the price of the aftercooler ranges from 59$ to 990$.

06. Damp Drain Duct

Damp drain duct provides ventilation to the cooling system. In the process of air conditioning inside the Cummins cooling system, the duct provides a passageway for air and water flow.

Moreover, the wet surface of the duct makes the air moist and damp, which creates a cooling effect. The price of the duct depends upon the volume of the cooling system.

Typically, it is available at the rate of $0.95 to $1.37 per square foot.

07. Water filter

Water filters are also a significant part of the cooling system. The impurities, unwanted substances, contamination, and pollutants present in either the flowing water or the cooling system.

It is essential to make the cooling system tidy to ensure the system’s efficiency. Moreover, it helps limit corrosion and inhibits the deterioration of the system.

The price of the filter ranges from $72-$82.

08. Water Pump

The function of a Cummins water pump is to thrust the coolant via the cooling system into the appliance and then move it over the radiator.

In the absence of a water pump, the coolant will not work efficiently. In other words, it enhances the circulation of water flow within the system.

Depending upon the power of the water pump, its cost varies from $461-$638.

09. Injector

Injectors work with the water pumps acting as their valves. The valves perform double functions.

It not only supplies fuel to the ignition chamber but also aids in the splashing of outfitted consumables.

Cummins Cooling System: What & Why?

As discussed earlier, the cooling system lowers the temperature and helps in stimulation. The full description of the process happening inside the engine is described here.

Water transfers via the heat exchanger and are pulled towards the water pump. The water flow is split here into two streams.

One stream moves towards the barrel belfry water transition over the damp drain duct. The passage is headed by the upward barrel head and infused sleeves.

The whole route is diluted. Water travels through this passage and is directed towards the Cummins after-cooling system.

The temperature regulator then adjusts the temperature in the flowing water. It can be adjusted manually—the other stream that ran out from the water crater and passed through the oil cooler.

In detailed discussion, it is noted that the water pump installed in the cooling system works on the principle of centrifugal force, which pushes the water forward to the engine’s frontal zone.

The damp drain duct enables the water to move over the barrel liners, in which injectors are placed.

The temperature is regulated through the thermostat. The whole process is repeated, and the stream of water is cooled at the desired temperature.

FAQs

The most frequently asked questions about the Cummins Cooling System Diagram are below.

What is the Cummins Cooling system diagram?

The Cummins Cooling system diagram is the pictorial representation of the cooling system depicting its various parts and the location of the different components in the system.

The interconnection of these parts and their function can be understood easily with the help of a labeled diagram.

After the understanding of the location of various factors, it is easy for the technicians to understand the significance of the components and to locate the wear and tear as well.

How much does the Cummins Cooling system cost?

The price of the Cummins cooling system varies depending upon the quality of components being installed. Various dealers sell the cooling system.

The price varies upon the locality as well as the service provider. The kit costs around $376.95.

How many parts are there in the Cummins cooling system diagram?

The Cummins cooling system provides the pictorial representation of the parts such as oscillation damper, water pump, injector, water filter, damp drain duct, waft squeezer, aftercooler, thermoregulator, idler sheave, associating cane, major oil transition, and fuel equip tunnel.

Grease pump, air blower, turbine, and shaft revolver.

What happens if the thermoregulator stops working in the Cummins cooling system?

If the thermoregulator stops working in the cooling system, there are chances for an unregulated temperature. It might cause an overheat or excessive drop in the temperature.

Extreme heat can cause the burst of the engine, and a disproportionate decrease in the temperature can cause the solidification of the flowing water.

The condition in which the engine’s temperature drops more than average is termed the ‘thermostat stuck open.

The faulty thermostat can be indicated with the temperature gauges pre-installed in the cooling system.

What is the difference between the Cummins system and the Lubricating system?

The lubricating system helps to grease the parts and to minimize the friction between the running machinery. It lubricates the engine and aids in the smooth functioning of the machine.

At the same time, the Cooling system assists in dropping the temperature of the engine and prevents the system from overheating.

What is the function of the turbocharger in the Cummins Cooling system diagram?

The turbocharger of the cooling system does the compression of flowing air in the engine. While compressing the air molecules, the particles come closer, reducing the space between them.

The decrease in the area allows more fuel to be injected into the engine. The turbocharger works on the principle of centripetal force.

The turbo allows the air particles to rotate. The turbocharger is connected to a duct further attached to the compressor.

Due to centripetal force, the air molecules are drawn inward and then forwarded to the intercooler installed in the engine.

Verdict

It is concluded that the diagram of the Cummins cooling system helps provide a complete illustration of the system. The significance of each component and its proper functioning can easily be understood by it.

The Cummins cooling system not only extracts the enormous heat from the engine but also regulates the temperature while operating the engine.

The determination of the exact temperature where the engine works more efficiently is also done with the help of it.
