SPARK PLUG

摘要

A unique universal bi-directional firing spark plug includes an elongated or non-elongated body (12) with an electrical connector (14) at one end. An absolute aerodynamic semispherical dome or shape (22) is secured to the other end of the body. At least one absolute aerodynamic semicircular electrode (28) is secured to the body adjacent to the dome or sphere electrode such that the semicircular electrode has its inner surface equidistantly spaced from the dome or sphere electrode's surface. The electrodes can be fabricated from various metals and/or alloys. Alternate embodiments of the invention includes two, three, four or five semicircular electrodes, all of which have a surface equidistally spaced from the aerodynamic semispherical dome or sphere electrode along its complete arc length.
