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： 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 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 tubing coupling and a method for connecting tubing sections in which one tubing section is placed upon another tubing section in an overlapping manner. The first tubing section (1) is enlarged in the cold state in the area (2) where it overlaps, and the enlarged area is then placed over the second tubing section (3). Subsequent heating of the enlarged area (2) results in shrinkage of the first tubing section (1) which produces a firm seating of the first tubing section (1), for example a plastic suction tube as an air inlet tube, on the second tubing section (3), for example a flange for attachment to the cylinder head of an internal combustion engine.

摘要： An intake air temperature control device for mixture-compressing internal combustion engines having an inlet flapper proportioning the flows of cold and preheated raw air into a duct junction and into raw air mixing duct, the flapper-adjusting wax thermostat being arranged inside a thermostat chamber into which branch flows of cold and preheated raw air are admitted through two calibrated branch inlets. A narrow annular gap through which the combined branch flows must pass assures an integrated response of the thermostat to changing temperatures and air intake speeds. A lost-motion drive connection and a biasing member produce a full-load correction of the adjusted temperature. The flapper drive members may have valve edges which cooperate with the calibrated branch inlets to open and close the latter.

摘要： The invention relates to an intake pipe for the intake air of an internal combustion engine. The intake pipe comprises a shift drum which provides continuous adjustment of the intake pipe length. The intake pipe comprises a housing constructed of individual disks which are joined in a sealing manner via ring grooves. The shift drum is preferably made of regulator disks so that it can be assembled without difficulty by alternately sliding a housing disk and a regulator disk on to the drive shaft. The intake channels are sealed by means of sealing lips which are joined to the regulator disks, for example by injection, and are axially supported on annular ribs forming part of the housing disks. This makes it possible to compensate for the tolerances of all of the components. Apart form being easier to assemble, an intake pipe constructed in the above manner also has a lower weight since no inserts are required to configure and seal the individual intake channels.

摘要： A oil-fill opening 12 for introducing lubricating oil into an internal combustion engine provided with a cap 15 which has a bayonet lock. On the outside of the wall of the oil-fill opening there is an oil separator 22 through which the blow-by gases from the crankcase are conveyed to the intake manifold and/or to the clean-air side of the air filter. Oil collected in the oil separator 22 is returned through a return port 23, 24 between the oil separator 22 and the oil-fill opening 12. To prevent oil from getting into the oil separator when oil is poured into the oil-fill opening 12 and backing up therein so that under certain circumstances it reaches the clean-air side of the air filter, a shutter 25 in the form of a rotary slide valve, which covers the return port 23, 24 between the oil separator 22 and the oil-fill opening 12 when the cap 15 is removed, is provided within the oil-fill opening. The turning of the cap 15 when the cap is opened causes the slide valve to positively cover the return port, and when the cap 15 is closed, the return port 23, 24 is again uncovered.
