Introduction

The Cummins 3094047 Water Inlet Connection is a component designed for use in heavy-duty trucks. It plays a role in the engine’s cooling system by facilitating the efficient transfer of coolant into the engine block. This part ensures that the engine maintains optimal operating temperatures, which is important for performance and longevity.

Basic Concepts of Water Inlet Connection

Water inlet connections in heavy-duty trucks are integral to the cooling system. They allow coolant to enter the engine block, where it absorbs heat generated by combustion. The coolant then circulates through the engine, transferring heat away from critical components. This process helps maintain engine temperature within specified limits, preventing overheating and potential damage ¹.

Purpose of the 3094047 Water Inlet Connection

The Cummins 3094047 Water Inlet Connection is specifically designed to connect the coolant supply line to the engine block. Its role within the engine cooling system is to provide a secure and efficient pathway for coolant to enter the engine. This ensures that the coolant can effectively absorb and dissipate heat, contributing to stable engine temperatures under various operating conditions.

Integration with Engine Components

1. Engine Block: The water inlet connection is directly attached to the engine block. It serves as the gateway for coolant to enter the block’s water jackets. This ensures that the coolant circulates around the cylinders and other critical areas, dissipating heat effectively.

2. Thermostat Housing: Often, the water inlet connection is part of or directly connected to the thermostat housing. This setup allows for regulated coolant flow based on the engine’s temperature, enhancing thermal efficiency and protecting the engine from overheating.

3. Coolant Hoses: The connection point for the coolant hoses is typically integrated into the water inlet. These hoses transport coolant from the radiator to the engine and back, creating a continuous cooling loop.

4. Radiator: The water inlet connection plays a role in the interface between the engine and the radiator. Coolant flows from the radiator through the inlet, into the engine block, and then back to the radiator for cooling.

5. Water Pump: The water inlet is also connected to the water pump, which drives the circulation of coolant throughout the engine system. Efficient coolant flow is vital for consistent engine temperature management.

6. Cooling System Sensors: Many modern engines have temperature sensors near the water inlet connection. These sensors monitor coolant temperature and provide data to the engine control unit (ECU) for optimal performance and efficiency.

Conclusion

The Cummins 3094047 Water Inlet Connection is a pivotal component that ensures the smooth operation of the engine’s cooling system by facilitating the entry and circulation of coolant. Its robust design, compatibility with various Cummins engines, and integration with key engine components make it an essential part of maintaining optimal engine performance and longevity.
