Intake silencer in vertical type engine

摘要

An intake silencer of a vertical-type engine includes two silencing chambers. A first intake silencing chamber is disposed adjacent to the body of the engine; a second intake silencing chamber is located upstream in a flow of intake air from the first intake silencing chamber, and receives the flow of intake air as input thereto. An output of the second intake silencing chamber becomes an input to the first intake silencing chamber. The second intake silencing chamber is disposed at an opposite end of the engine body from the cylinder head of the engine.
