Description

Von oben gesteuerte Viertakt-Einspritz-Brennkraftmaschine Die Erfindung betrifft von oben gesteuerte Viertakt-Einspritz-Brennkraftmaschine und bezweckt, das Ansauggeräusch zu dämpfen.Four-stroke injection internal combustion engine controlled from above. The invention concerns from above controlled four-stroke injection internal combustion engine and aims to dampen the suction noise.

Es ist bereits bei Vergasermaschinen bekannt, die Kühl- und Verbrennungsluft durch eine über dem Zylinderkopf liegende, mit Schlitzen versehene Haube anzusaugen. Bei diesen als Fahrzeugmotoren verwendeten Maschinen geringer Größe tritt das Bedürfnis nach Geräuschdämpfung nicht auf.It is already known in carburetor machines, the cooling and combustion air sucked in through a hood provided with slits above the cylinder head. In these small-sized machines used as vehicle engines, the need arises after noise attenuation does not appear.

Man hat ferner vorgeschlagen, bei Einspritz-Brennkraftmaschinen eine mit der Ansaugleitung verbundene Haube über den Zylinderkopf und dessen Steuerungsteile zu legen; dieselbe wird aber nicht von der Ansaugluft durchströmt.It has also been proposed in injection internal combustion engines a hood connected to the intake line over the cylinder head and its control parts to lay; but the intake air does not flow through it.

Gemäß der Erfindung ist eine solche Haube als unmittelbarer Ansaugbehälter ausgebildet, so daß sie als Ausgleichsraum wirkt und die Geräusche dämpft. Die Verbrennungsluft wird also nicht durch ein Ansaugrohr aus der Umgebung der Maschine angesaugt, sondern unmittelbar aus einem Ansaugbehälter a entnommen, der durch eine über dem Steuermechanismus angebrachte Schutzhaube b gebildet ist. Weiter wird nach der Erfindung die Haube b mit Schlitzen und Löchern c in zweckmäßiger Zahl, Größe und Anordnung versehen. Bei Anwendung dieser Mittel fällt das Ansauggeräusch entweder ganz weg oder wird doch auf ein Mindestmaß beschränkt.According to the invention, such a hood is used as a direct suction container designed so that it acts as a compensation space and attenuates the noise. The combustion air is therefore not sucked in from the environment of the machine through an intake pipe, but taken directly from a suction container a, which is by an above the control mechanism attached protective hood b is formed. Next, according to the invention, the hood b provided with slots and holes c in an appropriate number, size and arrangement. When using these agents, the suction noise either disappears or becomes but limited to a minimum.
