Abstract (en)
[origin: US2018283242A1] A variable valve gear for an internal combustion engine of a motor vehicle has a cam carrier which is arranged on a camshaft in a manner which prevents relative rotation and allows axial movement between a first axial position and a second axial position and has a first cam and a second cam. The first cam is designed for a normal mode of the internal combustion engine, in which the first cam keeps a first exhaust valve open in the exhaust stroke. The second cam is designed for an engine braking mode of the internal combustion engine, in which the second cam initially keeps the first exhaust valve closed in the compression stroke and/or in the exhaust stroke and opens the first exhaust valve before reaching a top dead center of a piston movement.
