Valve train for an internal combustion engine

An internal combustion engine, comprising a valve train, the vale train including:

• a camshaft and a cam follower, the camshaft including a first slide guide and a second slide guide;
• two first cams arranged on the camshaft in a torque-proof manner and at an axial distance from one another, each of the two first cams including an identical first cam contour;
• and
• two second cams arranged on the camshaft in a torque-proof manner and at an axial distance from one another, each of the two second cams including an identical second cam contour;
• wherein the two first cams and the two second cams alternate in an axial direction on the camshaft;
• wherein the cam follower is axially adjustable between a first position and a second position, the cam follower being drivingly connected to the two first cams in the first position, and drivingly connected to the two second cams in the second position;
• wherein the cam follower includes a mechanical adjustment device configured to interact with the camshaft, the mechanical adjustment device facilitating the axial adjustment of the cam follower between the first position and the second position, the mechanical adjustment device including an adjustable first mechanical engagement element configured to interact with the first slide guide when axially adjusting the cam follower from the first position to the second position and an adjustable second mechanical engagement element configured to interact with the second slide guide when axially adjusting the cam follower from the second position to the first position;
• and
• wherein the first slide guide and the second slide guide are outer circumferential grooves arranged on a sleeve, the sleeve arranged on the camshaft in an axially displaceable manner.
