This Twin Scroll Turbocharger VW EA111 is a crucial part in the crankcase of VW EA111 engines, responsible for enhancing engine performance through twin scroll technology. This results in improved airflow and reduced energy losses. The turbocharger has been manufactured by Kolbenschmidt, with an MPN of 79221600. Its dimensions are 20.0 x 80.0 x 140.0 mm. Dimensions are provided by the supplier and may include packaging dimensions. Crankshaft bearings are precision components facilitating smooth rotary motion between the crankshaft and engine block. Located within the engine’s main and connecting rod bearing bores, these bearings support significant loads and reduce friction generated by reciprocating piston motion. Typically manufactured from tri-metal or polymer-coated steel, they feature a split design for ease of installation and precise clearance control. Oil grooves and channels within the bearing surface maintain a hydrodynamic oil wedge, preventing metal-to-metal contact. Dimensional accuracy and material hardness are critical for maintaining engine performance and longevity, with variations existing for different engine families and load requirements.
