Why Does the Intake Runner Control Solenoid Have 2 Valves

Technology and design in the field of construction machinery is changing rapidly, and various key components are evolving in order to continuously improve the performance and efficiency of machinery and equipment. In this context, the intake control solenoid valve has become an important part of the engine system. Perhaps you've wondered why this critical component utilizes a two-valve design? Below, we will delve deeper into this question, explaining why intake control solenoids typically have two valves and revealing the importance and application of this design for construction machinery. By understanding how it works and functions, we can better understand why the dual valve design has become one of the key innovations in modern construction machinery.

Control of intake air flow

Unlike the diesel solenoid valve, the main task of the intake control solenoid valve is to control the intake airflow of the engine. Control of intake airflow is critical to engine performance and efficiency. To accomplish this, two valves are typically used to manage airflow.

Primary Control Valve

The primary control valve is one of the key components of the intake control solenoid. It is located in the main passage of the intake tract and controls the magnitude and direction of airflow based on the operating conditions of the unit. The operation of the primary control valve is controlled by signals from the engine control unit (ECU), which adjusts the intake airflow according to the engine load and RPM requirements to better match the operation of other diesel engine parts.

Secondary control valve

The secondary control valve is located before or after the primary control valve, usually in a branch line of the intake tract. Its purpose is to provide additional airflow control options for the engine. By adjusting the position of the secondary control valve, it is possible to alter the path of the airflow, for example, by sending a portion of the airflow back into the intake tract to reduce the amount of airflow. This helps to improve the fuel economy and responsiveness of the engine and also facilitates the operation of other accessories such as the starter motor and alternator.

Engine performance and efficiency

The dual-valve design of the intake control solenoid allows for optimum engine performance and efficiency under varying loads and speeds. By precisely controlling the intake airflow, the engine achieves better combustion efficiency, reduces emissions and provides faster response times. This is important for applications such as construction machinery and automobiles, which require reliable power under different operating conditions.

Conclusion

The dual-valve design of intake control solenoid valves is designed to improve engine performance and efficiency. The synergistic action of the primary and secondary control valves allows the engine to adapt to different operating conditions for optimal airflow control. This is critical for reliability and performance for mechanical equipment in fields such as construction machinery and automobiles. As a result, dual-valve design has become an important part of modern engine technology.
