Definitions
- the invention relates to a housing assembly for an internal combustion engine for receiving a flywheel with a flywheel housing, which is connected to a transmission housing. Furthermore, the invention relates to an internal combustion engine having at least two cylinders or rows of cylinders arranged in a V-shaped space, wherein in the V-shaped space an inlet header defining at least one inlet collecting space and a calming area for blow-by gases are arranged out of the crank space is, wherein the calming area is laterally limited by the crankcase and is separated from the Beersammeiraum by a partition wall.
- the maximum diameter of the flywheel is determined.
- the flywheel mass can thus be varied only within the flange diameter of the gear housing. In order to reduce the degree of irregularity, however, flywheel masses with a larger diameter are advantageous in some cases.
- Internal combustion engine with at least two cylinders arranged in a V-shape, with an inlet collector arranged in the V-shaped space between the cylinders, and with a V-shaped calming region for blow-by gases from the crankcase, the calming region being laterally is limited by the crankcase and by a top surface.
- each an internal combustion engine with V-shaped arranged cylinders is known, wherein in the V-shaped space between the cylinders, an inlet collector is arranged.
- a calming room for blow-by gases from the crankcase.
- the calming space is bounded laterally by the crankcase and upwards by a cover surface formed by the crankcase.
- the calming chamber communicates with the crank chamber on the one hand, and with the intake manifold on the other hand, wherein a small-sized oil separator is arranged between the calming chamber and the intake manifold.
- the cover surface of the settling chamber formed by the crankcase prevents the use of larger oil separators. Therefore, a relatively high oil entry into the intake manifold can not be excluded.
- the object of the invention is to reduce the degree of unevenness in the simplest possible way. Another object of the invention is to reduce oil entry into the intake system.
- the connecting element can - viewed in a longitudinal section through the longitudinal axis of the housing assembly - profiled, or be formed stepped.
- the connecting element preferably in a longitudinal axis of the housing assembly-containing plane is divided.
- flywheel housing and the gear housing facing each other flange surfaces, wherein the flange of the flywheel housing with respect to the flange of the gear housing is radially offset, and preferably wherein the flange of the gear housing a smaller average radial Distance from the longitudinal axis of the housing assembly, as the flange of the flywheel housing. It can further be provided that the maximum radial distance of the flange surface of the gear housing is smaller than the minimum radial distance of the flange surface of the flywheel housing.
- the partition is formed by a separate component from the crankcase, preferably by the inlet collector.
- the intake manifold can be bolted directly to the crankcase.
- a large-volume oil separator with pre-separation system can also be used. This makes it possible to substantially increase the oil separation rates of the blow-by gases.
- FIG. 1 shows a housing arrangement according to the invention in a longitudinal section in a first embodiment
- FIG. 2 shows a housing arrangement according to the invention in a longitudinal section in a second embodiment variant
- FIG 3 shows an internal combustion engine according to the invention in a cross section through the cylinder axes.
- the housing assembly 1 has a flywheel housing 2 and a transmission housing 3.
- a flywheel 4 is rotatably mounted about a longitudinal axis 5 of the housing assembly 1.
- a connecting element 6 is arranged, which is essentially formed by a ring.
- the ring may optionally be divided in a plane containing the longitudinal axis 5.
- the connecting element 6 is connected to mutually facing flange surface 7, 8 of the flywheel housing 2, and the transmission housing 3.
- the corresponding bearing surfaces of the connecting element 6 are designated 6a and 6b.
- the flange surface 7, 8 of the flywheel housing 2, or the gear housing 3 are radially offset from each other, wherein the flange 8 of the gear housing 3 has a smaller average radial distance r m2 from the longitudinal axis 5 of the housing assembly 1, as the flange 7 of the flywheel housing. 2 , which is denoted by r m i.
- the average distances are determined in each case as the arithmetic mean value between the largest and smallest distance of each flange surface 7, 8 from the longitudinal axis 5.
- the minimum radial distance r ⁇ of the flange surface 7 of the flywheel housing 2 from the longitudinal axis 5 is greater than the maximum radial distance r 2 of the transmission housing 3rd
- the connecting element 6 is formed as a ring with a flat end face.
- the connecting element 6 is profiled in the embodiment variant shown in Fig. 2, or executed stepped, which allows a cast version.
- the internal combustion engine 101 has at least two rows of cylinders 102, 103 arranged in a V-shape, which are arranged in a crankcase 104. On the crankcase 104 per cylinder row, a cylinder head 106, 107 is placed and screwed. In the V-shaped space 108 between the V-shaped rows of cylinders 102, 103 is arranged for both cylinder banks 102, 103 common intake manifold 109, wherein the intake manifold 109th _ _
- a calming region 110 for blow-by gases from the crank chamber 105 is formed in the V-shaped space 108 between the cylinder rows 102, 103.
- the side walls 110a, 110b of the calming portion 110 are formed by the crankcase 104.
- the calming portion 110 is closed by the inlet header 109 and separated from the inlet header space 109a of the inlet header 109 by a partition wall 111 formed by the inlet header 109.
- the intake manifold 109 is screwed directly to the crankcase 104 via fastening screws 112, as can be seen from FIG. 4. By removing the inlet header 109, the calming area 110 is easily accessible, whereby in this area an oil separator with pre-separation system can be accommodated very easily.
