Title:
内燃機関のシリンダヘッド構造
Document Type and Number:
Japanese Patent JP7302462
Kind Code:
B2
Abstract:
A spark plug includes a ground electrode, an insulator, and a center electrode. In a case where a first position of a surface of the ground electrode exposed to a side of an inner wall surface of a cylinder head is a most downstream position in an air flow direction between the center electrode and the ground electrode, and a second position of the inner wall surface of the cylinder head is a position closest to the center electrode on a downstream side of the center electrode in an air flow direction, the spark plug is installed at a position where the first position and the second position are on a same air flow line, or at a position where the first position is recessed to a side where the first position recedes from the inner wall surface than the second position.
