Automotive air filter for vertical engine air intake has fan fold truncated cone filter inert with volcano-shaped top supplementary air intake

摘要

An upright automotive air filter supplies air to a motor air intake. The filter has an intake air pipe to a bell intake (42) over a cylindrical housing (30). The housing contains a truncated cone filter insert (50) with a volcano-shaped top air intake (53) over fan-fold sidewalls (52). The bell intake has radial guide vanes that impart a tangential twist to incoming air.
