Camshaft Drive with Variable Camshaft Timing Cadillac ELR I

A timing chain is used for camshaft drive. There is a tensioner to control the tension of the chain. The engine is equipped with a variable camshaft timing system. The camshaft adjuster will readjust itself depending on the engine speed. The valve timing readjusts to reduce fuel consumption and provides optimal power and torque. The variable camshaft timing makes an exhaust gas recirculation unnecessary.
