PROBLEM TO BE SOLVED: To improve intake efficiency by decreasing an electrification charge amount.SOLUTION: A positive electric charge is electrified on a surface of an intake passage wall which defines an intake passage of an engine (1), and a self-discharge type static eliminator (10) for decreasing an electrification charge amount is arranged on the intake passage wall. The self-discharge type static eliminator (10) can decrease the electrification charge amount on a surface of the intake passage wall within a limited range with an installation point as a center, and the self-discharge type static eliminator (10) is installed on a face of the intake passage wall at a point at which the reduction of a flow passage cross section of intake air is induced by an electrification charge.SELECTED DRAWING: Figure 1 |
