Combustion chamber for diesel engines with inclined engine valves

Described herein is a new architecture of a combustion chamber for a diesel engine, which allows arranging the engine valves (VA1, VA2, VS1, VS2) according to an axis (VX) inclined with respect to the cylinder axis (CX) by an angle (±) greater than 8°, without reducing the swirl ratio obtained at the end of the compression stage.
