4042154: ARM;ROCKER,INTK

**Product Overview** - **Part Type**: Intake Rocker Arm - **Application**: Internal combustion engines (likely for automotive use) - **Function**: Transfers motion from the pushrod to the intake valve, controlling valve opening and closing. --- **Technical Characteristics** - **Material**: Typically made of stamped steel or aluminum, depending on engine application and performance requirements. - **Design**: May feature a roller bearing at the contact point with the valve stem for reduced friction and wear. --- **Features and Benefits** - Facilitates valve actuation in overhead valve (OHV) engines. - Contributes to overall valvetrain operation, affecting engine performance and efficiency. - May offer improved durability and reduced friction compared to non-roller designs (if it's a roller rocker arm). --- **Performance Considerations** - **Rocker Ratio**: Has a specific rocker ratio affecting valve lift and engine performance; common ratios range from 1.5:1 to 1.8:1 for automotive applications. - **Weight**: Its weight can affect the reciprocating mass of the valvetrain, impacting engine RPM capabilities. --- **Installation and Compatibility** - Specific to intake valve operation. - Must be compatible with the engine's valvetrain geometry and other components. - Proper installation and adjustment are crucial for optimal engine performance and longevity. --- Note: Specific dimensions or model compatibility for this part are not provided, but the information above gives a general understanding of intake rocker arms and their role in engine operation.
