Summary:The utility model relates to a four-valve necking-down combustion chamber for a diesel engine, which is characterized in that the bottom surface of the combustion chamber can make a center point as a maximum point and can be in a conic and upward convexity. The four-valve necking-down combustion chamber is used on the diesel engine of a high-power vehicle; oil bundles can be totally and uniformly sprayed to areas with strong vortex flow; under the action of the strong vortex flow, oil drops can have good atomization and can be sufficiently combusted, and accordingly, oil consumption is reduced, emission of carbon monoxide and hydrocarbon can be reduced and can satisfy a second European emission standard.
