  • Patent number: 5622156
    Abstract: In a ventilating arrangement for an internal combustion engine, a venting line for supplying venting gases from the engine crankcase to the air intake pipe includes an oil separator from which an oil return line extends downwardly on the outside of the engine crankcase front wall into an upwardly open oil pocket also arranged on the outside of the crankcase front wall so as to form a siphon therewith through which the oil can return from the oil separator to the oil sump in the oil pan under the crankcase against the excess pressure normally developing therein during engine operation.

  • Patent number: 5533474
    Abstract: A lubricating-oil device for an internal combustion engine having two cylinder banks and a lubricating oil circuit with a main oil passage in each cylinder bank comprises a casing cover which is mounted on the front of the engine and includes a heat exchanger and an oil filter with all required communication passages for the oil and a supply passage which interconnects the main oil passages in the cylinder banks and which is in communication with the oil filter outlet for concurrently supplying filtered oil from the oil filter to both main oil passages.

  • Patent number: 5477817
    Abstract: A casing cover for an internal combustion engine with an engine casing having two cylinder banks is mounted on one end of the engine casing and includes an oil cooler, an oil filter, an oil filter bypass arrangement and also a transverse cooling water passage in communication with main cooling water passages extending along the cylinder banks and a transverse oil passage in communication with main oil passages also extending along the cylinder banks, and comprises three adjacent but separate functional areas, a first lowermost area which includes the lubricating oil passages leading to and from the oil cooler, the oil filter and the main oil passages, a second functional area which includes a cooling water space receiving the oil cooler and is disposed above the first functional area and a third functional area which is disposed next to the second functional area and includes cooling water return passages receiving the cooling water from said cylinder banks.

  • Patent number: 5411001
    Abstract: In a fuel line arrangement in the cylinder housing of an internal combustion engine with cylinders arranged in line and upstanding mounting structures with support bores for the reception of plug-in fuel injection pumps formed on the sides of the cylinders a fuel return passage extends through the cylinder housing so as to intersect all the fuel pump support bores, a fuel supply passage extends through the cylinder housing parallel to the fuel return passage and oblique passages extend between the fuel supply passages and the respective fuel pump support bores for supplying fuel to the plug-in pumps within the fuel pump support bores, the oblique passages being arranged such that their outward extensions are within the confines of the fuel pump support bore top opening to facilitate drilling of the oblique bores.

  • Patent number: 4889090
    Abstract: The invention relates to a crankshaft drive for an internal-combustion engine of V-type having a crankshaft with two mutually offset crank pins per throw, the pins being inter-connected via a narrow intermediate element. In order to ensure an optimum axial guidance of two connecting rods mounted rotatably on the crank pins, even without an intermediate web, the intermediate element has a cross-sectional area which largely corresponds to the overlapping sectional areas of the two crank pins. Moreover, each connecting rod is guided by means of an axial stop surface arranged on the large connecting rod eye of the adjacent connecting rod.

  • Patent number: 4886023
    Abstract: The invention relates to a crankshaft drive for an internal-combustion engine of V-type with a crankshaft, which has two mutually offset crank pins per throw, which pins are interconnected via an intermediate web. In order both to minimize the amount of machining required on the intermediate web and to ensure an optimum axial guidance of two connecting rods mounted on the crank pins, the intermediate web has an axial stop collar on either side and the intermediate web is of an enlarged design such that the axial stop surface of the connecting rods cannot jut out from the projected area of the intermediate web in any crankshaft position.
