Mit einer Kurbelkastenspülung versehene Zweitakt-Brennkraft-maschine, bei der im Ansaugkanal eine an eine Schmierölleitung angeschlossene Düse angeordnet ist, die das Schmieröl aus einem Schmiermittelreservoir mittels Unterdruck ansaugt. Um auf konstruktiv einfache Weise eine den jeweiligen Anforderungen der Maschine entsprechende Schmierung und Kühlung des Kurbeltriebes sicherzustellen, ist eine Düseneinrichtung (57) zur Einbringung und Verteilung von Schmiermittel am Eintritt der Ansaugluft ins Kurbelgehäuse vorgesehen, die vorzugsweise einen nach Arteines Venturirohres ausgeführten Kanalabschnitt (60) am Eintritt der Ansaugluft umfaßt, der im Bereich seines engsten Querschnittes (61) zumindest eine mit Schmiermittelzuleitungen (65) in Verbindung stehende Düsenöffnung (62') aufweist (Figur 3). |

An aluminum cylinder block (1) of an engine has a plurality of cylinder bores (2), and intermediate marginal areas (17) defined between adjacent cylinder bores (2). A single water jacket (8) is formed in the cylinder block (8) to surround the plurality of cylinder bores (2), and a plurality of oil chutes (15) are also formed in the cylinder block (1) outside the water jacket (8) for allowing an oil to drop from a cylinder head (5) to a crankcase (14) therethrough. These oil chutes (15) are formed between adjacent intermediate marginal areas (17) so that they do not make the cylinder block (1) swell out. An air in the oil chutes (15) functions as a sound insulation layer against combustion noises generated in the cylinder bores (2). The air in the oil chutes (15) also serves as a heat insulation layer for a cooling water in the water jacket (8) so that warming up performance of the engine under a cold condition is improved. |

A two-stroke, U-type uniflow engine includes a cylinder block forming parallel first and second cylinders and a common combustion chamber connecting the first and second cylinders. First and second pistons are mounted for reciprocal, linear movement within the first and second cylinders respectively. The engine also includes a crank shaft having a crank pin and a one-piece forked connecting rod connecting each of the first and second pistons to the crank pin. The connecting rod is elastically, bilaterally flexible to accommodate variations between a maximum distance between the first and second pistons and a minimum distance between the first and second pistons and is in a relaxed state halfway between the maximum distance and the minimum distance. The central wall has a slot for passage of the connecting rod therethrough and angled notches which correspond to maximum angles of the connecting rod. The connecting rod is designed to minimize weight and length and the engine bore and stroke are selected to minimize the difference between the maximum and minimum distance of the wrist pin displacement in order to reduce vibrations and to increase engine output by maintaining high crankcase compression. |

Bei einem Zylinderkopf für mehrzylindrige Brennkraftmaschinen mit am Zylinderblock zu befestigenden Einzylinderköpfen aus Gußeisen oder Stahl, sind die Einzylinderköpfe (1) in ein gemeinsames Mantelgehäuse (18) aus Leichtmetall eingegossen. Dadurch wird eine optimale Kühlung an den kritischen Bereichen des Zylinderkopfbodens erreicht und dadurch Ventilsitzverzüge vermieden und die Klopfneigung bei Ottomotoren hintangehalten. |

Bei einer Brennkraftmaschine mit mindestens einer obenliegenden Nockenwelle 2, die an ihren Lagerstellen mittels Lagerdeckeln 3 am Zylinderkopf 1 befestigt ist, ist eine Befestigungsschraube des Lagerdeckels 3 als Hohlschraube 8 ausgebildet, durch deren axiale Durchgangsbohrung 15 eine zur Befestigung des Zylinderkopfes 1 am Zylinderblock 14 dienende Schraube 12 hindurchgeführt werden kann. Dadurch läßt sich der Zylinderkopf 1 mit der Nockenwelle 2 als Einheit vormontieren, und diese Einheit wird dann durch die Schrauben 12 am Zylinderblock 14 befestigt. Ein Nachziehen der Zylinderkopfschrauben 12 und eine Demontage des Zylinderkopfes 1 läßt sich daher ohne vorherige Demontage der Nockenwelle 2 ermöglichen. |
