Engine cylinder head

A cylinder head of a multi-cylinder engine having a plurality of cylinders aligned in a row, the cylinder head comprising:

• a plurality of ceiling parts provided to the respective cylinders and each forming a part of a combustion chamber;
• and
• a water jacket formed inside the cylinder head, wherein
• each of the plurality of ceiling parts is connected to an intake port including a primary port and a secondary port aligned in the cylinder-row direction, and an in-cylinder pressure sensor configured to measure a pressure fluctuation inside the respective cylinder is attached to the ceiling part so as to face inside the cylinder,
• a plug is attached to a hollow part of the cylinder head corresponding to a core print provided to a core of the water jacket, the plug being disposed at a position corresponding to a location between certain cylinders among the plurality of cylinders,
• the in-cylinder pressure sensor attached to the ceiling part of the cylinder adjacent to the plug is attached at a position on an opposite side from the plug with respect to a center axis of the cylinder in the cylinder-row direction, and
• positions of the primary port and the secondary port connected to each of the plurality of ceiling parts are interchanged in the cylinder-row direction according to the position of the in-cylinder pressure sensor attached to the ceiling part.
