摘要:
An adjustable intake pipe, especially for supplying combustion air to an internal combustion engine, which includes a collector chamber arranged in an essentially cylindrical control element. The collector chamber has a larger volume than required for the air supply, so the chamber is not used efficiently. In the invention, the collector chamber volume is used by arranging additional components of the intake tract defined by the intake pipe, i.e. of an internal combustion engine, within the collector chamber (11), for example, by arranging a resonance chamber (20) therein with the resonance chamber connected to the air supply system by through holes (19). This arrangement better utilizes the chamber volume and is particularly advantageous in motor vehicle engine compartments where limited space is available. The intake system also is more compact and has a lower overall weight.
摘要:
An air intake device for an internal combustion engine, in which the device includes at least one collecting vessel (10) as well as a plurality of intake ducts which extend separately toward different cylinders in the engine. The intake ducts extend into the collecting vessel and are formed from a flexible tube (16), such as a synthetic resin tube.
摘要:
An air intake device for an internal combustion engine which includes at least one collection manifold and intake ducts branching off separately to individual cylinders of the internal combustion engine. The intake lines extend to the collection manifold and are formed at least partially of a flexible tube, especially a rubber tube. The intake lines furthermore have stiff or variable-length portions which are divided into at least two segments disposed for movement independently of one another.
摘要:
An air intake system for intake air of an internal combustion engine comprising a filter insert (19) in a housing (10) connected to the air conducting system by a plurality of inlets (13) and an outlet (22). The air inlets are provided with individual intake nozzles or fittings and lead to a single common air chamber (20) in the filter housing. The inlets (13) can be individually opened and closed by flap valves (24), thereby allowing the acoustics to be influenced favorably and enabling, for example, the respective intake fittings to be connected or disconnected depending on the temperature. The intake system requires only a limited number of components, and the design of the preferably wedge-shaped air chamber minimizes flow losses in the housing, which in turn decreases the intake noise. Shunt resonators (28) can also be formed using cover elements (29) and (30).
摘要:
A tension clamp for releasably joining two components. The clamp is anchored on a first component 10 by a mounting element 18 and is hooked onto the second component 11. The mounting element 18 is inserted under resilient bias into securing elements 17 on the first component, and has a resilient portion which produces the tension forces for joining the two components 10 and 11. The locking hook 20, which hooks onto the second component 11, is connected to the mounting element 18 by an intermediate link 19 and is preferably a plastic injection molding.
摘要:
A linkage connection for connecting a wax thermostat and membrane actuator drive assembly to a flapper-type flow proportioning valve in the air intake system of a carburetor-equipped internal combustion engine, the connection comprising a connecting cylinder formation in the flapper wall with a transverse slot and a groove in an extension of the thermostat housing with two positioning flanks which cooperate with the connecting cylinder.
摘要:
A duct system suitable for use as an intake manifold for an internal combustion engine, including flap valves (13) for selective opening and closing of the ducts. The positions of the valves are continuously adjustable in order to produce a swirl in the flow of combustion air. To achieve this, a high degree of angular precision is required in the positioning of the valves. Intake manifold manufacturing tolerances need to be compensated during assembly of the valves. A valve adjusting mechanism is provided in mechanical couplings (23) of the valve linkage between the position adjusting motor (19) and the flap valves (13).
摘要:
An induction device for an internal combustion engine with an intake pipe having dimensions which can be varied within predetermined limits. The intake pipe is made up of at least one resonance pipe (R) coupled via a resonance volume (43) with at least one ram pipe (S) leading to an inlet of a respective cylinder of the engine. A supercharging of the resonance pipe and/or the ram pipe can be realized in the entire intake pipe, and the dimensions of resonance pipes (R) and the ram pipes (S) can be continuously varied within predetermined limits.
摘要:
A suction or air intake module for an internal combustion engine comprising an air suction pipe made of synthetic resin material and a flange joint at the air intake on the cylinder head housing of the internal combustion engine. The air suction pipe is a one-piece blown element of synthetic resin material and is disposed by a spring in a housing part of the air intake module with the air outlet end of the air suction pipe extending into the area of a connection between the housing part and the cylinder head housing. A flange is arranged in the connecting area between the housing part and the cylinder head housing, the flange forming a single piece with the housing part and enabling the housing part to be sealingly attached to the air inlet of the cylinder head housing.
摘要:
An air filter for an for an air intake of an internal combustion engine. The filter includes a housing with a raw air inlet and a clean air outlet and an annular filter element having a pleated filter medium disposed therein. At least one buttressing element is provided to support the filter medium at the clean air side. The buttressing element has a knife-edge buttress disposed on the housing that extends to a position of maximum flexure of the filter element. The knife-edge buttress is further provided with a support shoe disposed thereon such that the shoe supports the filter element.
