Definitions

  • the invention relates to an internal combustion engine according to the preamble of claim 1.
  • the cooling jacket is part of the cylinder crankcase and the liner is inserted into the cooling jacket.
  • the force of the cylinder head bolts is at least partially transmitted to the crankcase via the cooling jacket.
  • the object of the invention is to reduce the weight of a generic internal combustion engine.
  • the cooling jacket can consist of a plastic, for example a polyamide, a metal foam or another material, which has a lower specific weight than the usual cast materials. This reduces the weight of the internal combustion engine. Since these materials also generally have a low thermal conductivity, an almost heat-tight design of the cooling jacket is made possible.
  • the coolant space is preferably formed by an open channel provided in the inner surface of the cooling jacket, which is covered by the outer surface of the liner.
  • the open channel could also be arranged in the outer surface of the liner and covered by the inner surface of the cooling jacket.
  • the invention can advantageously be applied to an internal combustion engine with two or more cylinders arranged in series.
  • the cooling jacket surrounds the cylinder liners of all cylinders, i.e. has a number of cylindrical or partially cylindrical cavities corresponding to the number of cylinder liners, and it delimits its own cooling liquid chamber with the cylinder liner of each cylinder, which has its own inflow connection at the upper end and its own return flow connection communicates at the bottom of the cooling jacket. This enables individual cooling of each liner.
  • the liners can be arranged separately from one another, in which case the cooling jacket has separate cylindrical cavities for the liners, the inner surfaces of the cavities delimiting, for example, helical cooling channels with the outer surfaces of the liners.
  • transverse channels can be provided in the cooling jacket, which channels are connected on the one hand to an inflow connection and on the other hand to the start of a cooling channel.
  • the liners are cast together, that is to say formed from one component, or they abut one another.
  • the cooling jacket has a number of partially cylindrical cavities corresponding to the number of liners, the inner surfaces of which each extend around a liner up to the web between adjacent liners.
  • a coolant space in the form of a cooling channel is provided in each inner surface, which extends in a zigzag shape from one side to the other side of the web over the inner surface and at the upper end of the cooling jacket with an inflow connection and at the lower end of the cooling jacket with a backflow connection communicates.
  • transverse channels are provided in this, which are each arranged between the beginning of a zigzag-shaped cooling channel and an inflow connection.
  • the cooling jacket can have openings through which the cylinder head bolts extend. If these breakthroughs are used at the same time to return the lubricating oil from the cylinder head to the crankcase, simple and space-saving cooling of the lubricating oil is made possible by providing in the cooling jacket a chamber through which the lubricating oil flows and in which an oil cooler can be arranged to reinforce the recooling connected to the coolant circuit of the liner (s).
  • this oil cooler can have at least one plate which is in heat-conducting connection with an inflow connection for the cooling liquid which extends through the chamber.
  • the internal combustion engine has a crankcase 1, a schematically illustrated cylinder head 2 and, in the exemplary embodiment, a twin cylinder which consists of two cylinder liners 3 and 4 combined into a unit and a cooling jacket 5 surrounding them and representing a separate component consists.
  • the liners 3 and 4 are integrally formed on the crankcase 1 and extend to the cylinder head 2.
  • the cylinder head bolts (not shown) are transmitted from the cylinder head 2 to the crankcase 1 via the liners 3, 4.
  • the cooling jacket is thereby clamped between the cylinder head 2 and a bearing surface 1a on the crankcase 1 with the interposition of seals, not shown.
  • the cooling jacket 5 can be made of a light material, since it has no main task, but only serves to limit cooling channels together with the liners as described below.
  • the cooling jacket 5 can consist, for example, of a plastic, such as polyamide, a metal foam or another material with a lower specific weight than the conventional cast materials.
  • the cooling jacket 5 has two partially cylindrical cavities 6 and 7 (FIG. 4), the inner surfaces 8 and 9 of which each extend around a liner 3 and 4 as far as the web 10 connecting the two liners.
  • each inner surface 8, 9 there is an open cooling channel 11 or 12, which runs in a zigzag or serpentine form from one side to the other side of the web 10, as can be seen from FIG. 3, in which the web 10 is shown in dash-dotted lines is.
  • the cooling channels 11 and 12 are covered by the liners 3 and 4.
  • the cooling liquid is supplied to the cooling channel 11 via an inflow connection 13, which opens into a connecting channel 14 in the inner surface 8 of the cavity 7 and is connected to a transverse channel 15 in the web 10 between the liners 3, 4.
  • the other end of the transverse duct 15 opens into the upper end 16 of the cooling duct 11.
  • the lower end 17 of the cooling duct 11 is connected to a return flow connection 18, which is on the same side as the inflow connection 13 but below it. as shown in Fig. 4.
  • the coolant thus flows from the inlet channel 13 through the connecting channel 14 and the transverse channel 15 into the cooling channel 11, flows through it from top to bottom and enters the reflux connection 18 at the end 17.
  • the liner 4 is cooled in an analogous manner.
  • the cooling liquid is supplied through an inflow connection 20, enters a connecting channel 21 in the inner surface 9 of the cavity 7 and from there enters an invisible transverse channel, which is provided in the web 10 below the transverse channel 15, as is shown in FIG 3 visible form of the connecting channel 21 is illustrated. From this transverse channel, the cooling liquid flows via a channel 22 (FIG. 4) corresponding in shape to the connecting channel 21 into the upper end 23 of the cooling channel 12 and down through this to the lower end 24, which in turn is connected to a return flow connection 25, which is on the side of the inflow connection 20, but below this.
  • each liner 3, 4 is individually cooled for itself.
  • the cooling jacket 5 has openings 26 through which the cylinder head screws (not shown) extend and which at the same time serve to return the lubricating oil from the cylinder head 2 into the crankcase 1.
  • the lubricating oil is cooled.
  • a chamber 27 can be provided in the cooling jacket 5, through which the lubricating oil flows and in which, as shown in FIG. 5, an oil cooler 28 can be arranged, which the inflow connections 13 'and 20, which extend through the chamber 27, is in thermally conductive connection.
  • the oil cooler 28 consists, for example, of at least one metal plate which is fastened on the tubular inflow connections, which are also made of metal.
  • the inflow ports 13 'and 20' are further apart in this embodiment and extend a longer distance within the chamber 27 than in the first embodiment, so that the plate communicates with the inflow ports over a larger area.
  • the invention can also be applied to an internal combustion engine with only one cylinder or with more than two cylinders, the liners either being separate from one another or being connected or abutting one another. If the liners are arranged separately, the cooling jacket completely surrounds each liner and each liner can be surrounded by a cooling liquid space, e.g. a helical cooling channel
