FIELD: engine building.
SUBSTANCE: invention can be used in internal combustion engines of vehicles. An adjustable valve drive is intended for an internal combustion engine with the first valve of a gas distribution mechanism, in particular an exhaust valve, and the second valve of the gas distribution mechanism, in particular an exhaust valve. The valve drive includes system (26) of cams with an adjustable position. System (26) of cams contains base (34) for cams with the possibility of axial displacement, equipped with first cam (40) for the first valve of the gas distribution mechanism, second cam (42) made with the possibility of displacement relatively to the first one along the axis, third cam (44) for the second valve of the gas distribution mechanism, and fourth cam (46) made with the possibility of displacement relatively to the third one along the axis. A position of first cam (40) installed with the possibility of actuation of the first valve of the gas distribution mechanism and third cam (44) installed with the possibility of actuation of the second valve of the gas distribution mechanism, or a position of second cam (42) installed with the possibility of actuation of the first valve of the gas distribution mechanism and fourth cam (46) installed with the possibility of actuation of the second valve of the gas distribution mechanism is set depending on the axial position of base (34). First cam (40), second cam (42), third cam (44), and fourth cam (46) are made different compared to a cam of zero move. First cam (40) and third cam (44) are made the same. Second cam (42) and fourth cam (46) are made different. A vehicle is disclosed.
EFFECT: provision of the expansion of functionality of an adjustable valve drive without an increase in a number of cams of a base in a system of cams with an adjustable position.
