Abstract:
A device for regulating the intake air of an internal combustion engine, including a pressure box (41), a sealing system on the pressure box, and an opening (42) in the pressure box. A movable mechanical part (43) extends into the pressure box (41) through the opening (42), and the sealing system seals the pressure box (41) in relation to the movable mechanical part. The sealing system includes a synthetic resin friction bearing (45) which contacts the movable part (43) over a predetermined length and which is firmly anchored in the opening (42) of the pressure box (41) by the sealing system. A Teflon ring is arranged in the sealing system at one end of the synthetic resin friction bearing (45) surrounding the movable part (43) in such a way that it is pressure tight.
Abstract:
Provided is a method of providing warm air to the intake of a engine of a vehicle to improve fuel economy and reduce emissions of said vehicle. The method includes the steps of:transferring warm air directly exiting a radiator to an air intake of an engine using a variable vane which flexes and rebounds to continuously adjust an amount of warm air being supplied to said air intake in response to various engine loads;allowing said variable vane to flex and rotate an air deflection surface of said variable vane to a position which supplies an increased volume of warm air to said air intake as a warm air load against said air deflection surface is increased; andallowing said variable vane to rebound and rotate said air deflection surface to a position which supplies a decreased volume of warm air to said air intake as a warm air load against the air deflection surface of said variable vane is decreased. The invention also provides an apparatus for practicing the method.
Abstract:
A valve control mechanism for turbo-charged internal combustion engines having a plurality of valves controlling fluid flow paths to devices regulating engine operation and so arranged that when the pressure in the air fuel induction system increases from a vacuum to a positive pressure the control paths are closed to interrupt operation of the control devices.
Abstract:
An air induction pipe for an air cleaner formed of a synthetic resin and as a pair of longitudinally divided pipe members. Each of the pipe members includes a fixing portion integrally formed thereon for mounting a diaphragm unit which is used to control air flow. The diaphragm unit is interposed between the fixing portions, and the pipe members combined to form the air induction pipe, thereby to fixedly secure the diaphragm unit to the air induction pipe only by the pipe members.
