Abstract

An internal combustion engine for a motor vehicle includes a crankshaft, a camshaft, a cylinder, a piston movably disposed in the cylinder and coupled to the crankshaft for driving the crankshaft, a first gas exchange valve which is assigned to the cylinder, a first valve clearance compensation device, where via the first valve clearance compensation device the first gas exchange valve is displaceable between a first open position and a first closed position by a first cam of the camshaft, and a control unit. The control unit is configured to align the camshaft such that the first valve clearance compensation device is pressure-loaded in the idle state of the crankshaft by a plateau area assigned to the first cam to hold the first gas exchange valve in the first open position.
