ABSTRACT:
A distributor for a vehicle includes a housing and a cap operatively positioned on the housing for defining a closed space therebetween. A central electrode and a side electrode are operatively mounted within the cap in a predetermined disposition. A distributor rotor is rotatably mounted relative to the housing and projects within the closed space, the distributor rotor includes an upper end and a lower end. At least one fin is mounted adjacent to the upper end of the distributor rotor for rotation together with the distributor rotor. An air flow guiding member projects into the closed space. An air intake aperture is provided for introducing ambient air into the closed space. A discharge aperture is formed in the cap for discharging swirling air flow induced by rotation of the distributor rotor to travel from the air intake aperture along the air flow guiding member and through the discharge aperture to the atmosphere. The discharge aperture is formed in the cap at a position above the distributor rotor and the air intake aperture is formed in the cap or the housing at a position in a lower portion of the cap or the housing for enabling acidic material generated by a spark to be discharged through the discharge aperture by the swirling air flow.
