With a strong presence in the automotive industry, Cummins is renowned for its high-quality diesel engines and components, such as the 3328445 Intake Air Heater, which are designed to meet the demanding requirements of heavy-duty applications.

Intake Air Heater Compatibility with Cummins Engines

The Cummins part 3328445, an Intake Air Heater, is designed to enhance the performance of several Cummins engine models by ensuring that the air entering the engine is at an optimal temperature. This is particularly crucial in cold weather conditions where cold air can negatively impact engine efficiency and performance.

ISM CM570 and QSM11 CM570

The ISM CM570 and QSM11 CM570 engines benefit from the Intake Air Heater as it helps in reducing the time required for the engine to reach optimal operating temperature. This heater ensures that the air intake is warmed before it enters the combustion chamber, which can lead to improved fuel efficiency and reduced emissions.

ISM11 CM876 SN and M11 CELECT PLUS

For the ISM11 CM876 SN and M11 CELECT PLUS engines, the Intake Air Heater plays a vital role in maintaining consistent engine performance across varying temperatures. These engines are often used in heavy-duty applications where consistent performance is critical. The heater ensures that the air intake is adequately warmed, which helps in maintaining the engine’s efficiency and reliability, especially in colder climates.

M11 MECHANICAL

The M11 MECHANICAL engine also integrates the Intake Air Heater to improve cold-start performance and overall engine efficiency. This engine is known for its durability and reliability in demanding conditions. The heater ensures that the engine starts smoothly and operates efficiently, even in low temperatures, by warming the intake air to an optimal level.

Each of these engines, despite their different specifications and applications, relies on the Intake Air Heater to maintain optimal performance and efficiency. The heater’s role in warming the intake air is crucial for ensuring that the engine operates at peak performance, regardless of the ambient temperature.

Role of Part 3328445 Intake Air Heater in Engine Systems

The intake air heater, identified by part number 3328445, is a component in the air induction system of an engine. Its primary function is to warm the incoming air before it enters the combustion chamber. This warming process is particularly important in cold weather conditions, where the air density is higher, and the air temperature is lower.

When the intake air heater is activated, it heats the air that passes through the air intake duct (AID). This heated air then flows into the air cleaner assembly, where it is filtered to remove any impurities. The clean, warm air subsequently moves through the throttle body and into the intake manifold.

The intake manifold distributes the heated air to the individual cylinders of the engine. In diesel engines, the intake air heater plays a significant role during the starting process. Warmer air aids in better fuel atomization and combustion, which is vital for smooth engine start-up in cold environments.

In summary, the intake air heater (part 3328445) ensures that the air entering the engine is at an optimal temperature, enhancing engine performance, especially during cold starts. This component works in conjunction with the air intake duct, air cleaner, throttle body, and intake manifold to deliver efficient and reliable engine operation ³.

Conclusion

The Cummins 3328445 Intake Air Heater plays a significant role in enhancing the performance and efficiency of heavy-duty truck engines, particularly in cold weather conditions. By preheating the intake air, it ensures optimal engine operation, reduces wear and tear, improves fuel efficiency, and contributes to lower emissions. Proper installation, regular maintenance, and understanding its compatibility with various Cummins engines are key to maximizing the benefits of this part.
