4042134: TAPPET

### Product Description for Tappets #### Technical Specifications - **Function**: - Converts rotational motion of the camshaft into linear motion to activate engine valves. - **Types**: - Solid, Hydraulic, or Roller. - Hydraulic tappets adjust clearance automatically using engine oil pressure. #### General Characteristics - **Role in Engine**: - Transmit camshaft movements to push rods and rocker arms, opening and closing valves. This process affects the air-fuel mixture in combustion chambers. - **Hydraulic Tappet Features**: - Eliminates the need for manual clearance adjustments. - Reduces noise and improves engine efficiency by maintaining optimal valve clearance. #### Applications - **Use in Engines**: - Essential in all automotive engines for precise valve operation and efficient combustion. - **Compatibility**: - Designed for specific engine models; some may feature hydraulic systems for self-adjusting capabilities. #### Key Features - **Self-Adjusting**: - Automatically maintains proper clearance, reducing manual adjustments. - **Lubrication**: - Lubricated by engine oil to reduce friction and wear on moving parts. #### Additional Information - **Maintenance**: - Regular maintenance, such as ensuring a clean oil supply, is vital for proper functioning. - **Noise Reduction**: - Consider products like LIQUI MOLY's Tappet Stop Noise additive to mitigate noise issues associated with hydraulic tappets.
