Abstract: An air cleaner for an internal combustion engine is arranged to reduce intake noise. The air cleaner includes an air cleaner element for cleaning an intake air, and an elastic member for reducing intake noise by utilizing an inside space of the air cleaner. An inside space of the elastic member is in communication with the inside space of the air cleaner through a communication passage. Preferably, a surrounding space formed between the elastic member and a case portion for receiving the elastic member is opened to the outside.

Abstract: The present disclosure describes a drain plug structure for an oil pan for an internal combustion engine. The drain plug structure closes off a drain hole disposed in a bottom portion of the oil pan. The drain plug structure includes a columnar stopper portion inserted into the drain hole and rotated to prevent withdrawal. A sealing member is fitted to an outer periphery of the columnar stopper portion. An operating portion for a rotation operation is disposed on an outside exposed end portion of the columnar stopper portion. A plurality of cantilevered arcuate arm portions project radially outwards from the outside exposed end portion of the columnar stopper portion and are arranged in series along a circumferential direction. A loosening-prevention meshing portion is disposed on a tip end portion of each arcuate arm portion and an opening edge portion of the drain hole.

Abstract: Intake sound reduction device for internal combustion engine includes an elastic member formed into substantially cylindrical shape and having an open base end, a top end sealed by an end surface wall and a bellows circumferential wall; a base plate retaining base end of elastic member; and a communication pipe whose one end is connected to base plate so that a volume chamber formed inside elastic member communicates with an intake passage of the engine. Intake sound reduction device has first resonance system formed by expansion and contraction in axial direction of elastic member and second resonance system formed by film-vibration of end surface wall. When either one of resonance frequencies of the first and second resonance systems is primary resonance frequency and the other is secondary resonance frequency, the primary resonance frequency is set to 30˜200 Hz and the secondary resonance frequency is set to 50˜300 Hz.
