Abstract

An intake system of a vehicle, includes an air cleaner case, an air filter that is arranged inside the air cleaner case and positively charged, and a self discharge type static eliminator that decreases an amount of electrification charge on a wall surface of the air cleaner case within a limited range about a location where the self discharge type static eliminator is installed, when the self discharge type static eliminator is installed on the wall surface of the air cleaner case. An peripheral edge part of the air filter is held by an air filter holding part of the air cleaner case. The self discharge type static eliminator is installed on an outer wall surface of the air filter holding part of the air cleaner case.

First claim

What is claimed is:

1. An intake system of a vehicle comprising:
an air cleaner case, wherein the air cleaner case:
includes an air inflow-side air cleaner case and an air outflow-side air cleaner case; and
is made from a non-conductive synthetic resin material;

an air filter, wherein:
the air filter is removably arranged inside the air cleaner case; and
a peripheral edge part of the air filter is held at a connecting part between the air inflow-side air cleaner case and the air outflow-side air cleaner case;

a self discharge type static eliminator, wherein the self discharge type static eliminator:
is a conductive layer disposed only on an outer wall surface of the connecting part of the air cleaner case; and
has a corner part configured to discharge a positive charge when air moves into the corner part of the self discharge type static eliminator.

2. The intake system according to claim 1 , wherein
the air inflow-side air cleaner case and the air outflow-side air cleaner case are provided with connection flanges, respectively, in the connection part between the air inflow-side air cleaner case and the air outflow-side air cleaner case, the connection flanges projecting outwardly from an outer wall surface of the air inflow-side air cleaner case and an outer wall surface of the air outflow-side air cleaner case, respectively,
the peripheral edge part of the air filter is held between the connection flange of the air inflow-side air cleaner case and the connection flange of the air outflow-side air cleaner case, and
the self discharge type static eliminator is installed on at least one of an outer wall surface of the connection flange of the air inflow-side air cleaner case, and an outer wall surface of the connection flange of the air outflow-side air cleaner case.

3. The intake system according to claim 2 , wherein
the air filter includes filter paper and a filter paper support frame that supports a periphery of the filter paper, and
the filter paper support frame is held between the connection flange of the air inflow-side air cleaner case and the connection flange of the air outflow-side air cleaner case.

4. The intake system according to claim 1 , wherein the self discharge type static eliminator is metallic foil that is adhered onto a wall surface of the air cleaner case by a conductive adhesive.

5. The intake system according to claim 4 , wherein the self discharge type static eliminator has a long and narrow rectangular flat plate shape.

6. The intake system according to claim 4 , wherein the self discharge type static eliminator has a sharp end part.

7. The intake system according to claim 1 , wherein the self discharge type static eliminator is formed integrally on a wall surface of the air cleaner case.
