When the upper magnet is activated, the armature plate is held upright. The valve is in the closed position.
The e-valve system operates each valve individually and independently of the crankshaft position and of the other valves.

independently from the others and independently from the piston position.
When the upper magnet’s magnetic field is disrupted, the armature plate is pulled downward by springs. Actuation of the lower magnet maintains the valve in the opened position.

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.
Compression
The total independence of each valve allows the deactivation of some cylinders at low engine speeds. Therefore, the engine runs with half of the cylinders, with two cylinders instead of four cylinders in a 4 cylinder engine.
