Abstract
A spark plug for increasing a combustion speed of a gasoline engine may include electrodes of a spark plug, which ignite a mixture of fuel and air in a combustion chamber of an internal combustion engine, wherein the electrodes of a spark plug are positioned at a position where a flow velocity is high, and one end portion of a body of the spark plug and an end portion of a cylinder head on which the spark plug is disposed are positioned on a diagonal line to induce a tumble flow downward and allow a flame generated at the spark plug to expand toward a center portion of the combustion chamber where turbulent flow energy is high, such that both an initial combustion speed and a main combustion speed are high.
