FIELD: internal combustion engines.
SUBSTANCE: invention can be used in the internal combustion engines. Combination of valve (1) and seat (5) of valve for internal combustion engine of vehicle. Valve is gas outlet and/or gas exchange. Valve has valve stem (2) and valve plate (3). Valve plate has front surface (3.1) and rear surface (3.2). Front surface of valve plate is convex outside. Valve is made in form of solid valve. Neutral axis (4) of valve plate passes separate sections on side of load of imaginary base plane (BE). Base plane (BE) passes through effective center (M) of bearing surface (3.3) of valve on valve plate and across valve stem. Neutral axis of valve plate is convex in direction of load side (P). Area (4.1) of the neutral axis apex relative to the valve stem passes eccentrically. Disclosed is an industrial vehicle.
EFFECT: technical result consists in reduction of valve and valve seat wear at low content of soot in exhaust gas and absence of hydrodynamic disadvantages.
