Mechanical Structure of 2a87dme Scheduled VANOS?

[JuniperLynn]

Here is an introduction to the VANOS system: 1. Introduction: BMW's VANOS system (fully known as Variable Camshaft Timing Control System) is a camshaft control device that combines hydraulics and mechanics, operated by the vehicle's engine management system. It can continuously adjust the timing and lift of both intake and exhaust valves. 2. Features: Increases torque output in the mid-to-low RPM range; reduces residual exhaust gas during idle by minimizing valve overlap angle; in partial load conditions, decreases nitrogen oxide content through internal cylinder exhaust gas recirculation, while quickly heating the three-way catalytic converter, producing less exhaust after cold starts, and reducing fuel consumption.
