Valeo - Electromagnetic valve actuation

  1. 1. The e-Valve system replaces the traditional camshaft system > Electromagnetic valve actuation The e-valve system operates each valve individually and independently of the The total independence of each crankshaft position and of the other valves. valve allows the deactivation of some cylinders at low engine When the upper magnet When the upper magnet’s magnetic field speeds. Therefore, the engine is activated, the armature is disrupted, the armature plate is pulled runs with half of the cylinders, plate is held upright. downward by springs. Actuation of the lower with two cylinders instead of four The valve is in the closed magnet maintains the valve in the opened cylinders in a 4 cylinder engine. position. position. Actuator Magnet Armature plate attached Springs to the valve stem Decompression Cups Valve Compression The flexible e-Valve system allows infinitely variable valve timing and valve opening duration. This control flexibility increases torque at low engine speeds and optimizes engine output when instant power is required. CharaCTerisTiCs n Fuel consumption reduced by 15-20 %. n CO2 emissions reduced by 15- 20 %. n Low-end torque increased by 15-20 %. n Optimization of air-fuel mixture. © VALEO n Each engine valve operates independently from the others and independently from the piston position.
