    FIELD OF THE INVENTION The invention relates to mechanical engineering, namely, to exhaust manifolds of a series and V-type internal combustion engines. pressurized, preferably having from four to ten cylinders. Famous exhaust manifolds of daylight combustion engines with supercharging and at least four rows of cylinders contain a cylindrical body with an outlet end communicating with the turbine of the supercharging unit and with inlet pipes placed on its side and communicating with each of the cylinders moreover, the cross-section of the pipes on the collector side is less than its cross-section & neither on the side of cylinders ij. However, in the known exhaust manifolds there are some energy losses during the transfer of exhaust gas from one trezka to another. The circuit of the invention is to increase the efficiency of the engine by increasing the ejection effect and accelerating the outflow of gases into the exhaust manifold. The goal is achieved by the fact that in the exhaust manifold of an internal combustion engine with a supercharged engine and at least four rows of S cylinders comprising a cylindrical body with an outlet end communicated with the turbine of the supercharging unit and with the inlet nozzles located on its side and communicated with each of the cylinders, the cross section of the nozzles on the collector side is less than its cross section on the cylinder side, the casing is made of constant diameter, the area ratio is pop & river cross section the bosses on the collector side to the cross section on the cylinder side is 0.3-0.8, preferably 0.4-0.5. The case diameter is O, 30O, 75 of the bore diameter of the cylinder. The body consists of fixedly connected segments, centered along the axis. Segments of the case pianos along with inlets. The acupressure of the withdrawal end of the casing with the turbine is ignored at the Iomoshi pipe of the spiral-shaped wire. The pipeline is made according to a cross-section. The cross section of the pipeline decreases linearly to zero. The pipeline is made in the form of a full 360 ° helix. The pipeline is made in the form of two docked helixes with a double entrance. Both half helixes are communicated between the two. The half helixes are isolated from each other. The pipeline is made in the shape of a truncated cone, the smaller base of which communicates with the outlet end of the housing, and the larger overlaps the turbine impeller and contains a fairing and blades placed between the walls of the conductor and the fairing. FIG. 1 - parts of the exhaust scavenger in the first embodiment of the inlet nozzles, longitudinal section; in fig. 2 shows section A in FIG. one; in FIG. 3 a part of the manifold for a supercharged engine; in fig. 4 - the part of the collector in the second version is made of 1 inlet nozzles; on phage. 5 - the same, with the third option inlet pipes; in fig. 6 is a view of the end face of the collector; the view of FIG. 5i option of connecting the Kansd connection with the collector; in fig. 7 shows a section B-B in FIG. 3; in fig. 8 is the fourth embodiment of the invention of FIG. 9 - exhaust manifold (simplified version), general view; in fig. Yu exhaust manifold (improved version), longitudinal section; Fig. 11 is the same, front view; in fig. 12 section of the GG figure 11; in fig. 13 section C-C. in fig. 12; in fig. 14 view of the helix according to the first embodiment; in fig. 15 - the same section; in fig. 16 is a development of the helix of FIG. 14; in fig. 17 is a view of the helix according to the second embodiment; in fig. 18 is a development of the helix of FIG. 1 in FIG. 19 - the third option ispop & shsh spirals; in fig. 20 - speraln on Fig; at f. 21 - a transverse section of the second variant of the somatic & Ninvs of the outlet manifold with a turbine; on isr. 22 is a sectional view of FIG. 21. The exhaust manifold of an internal combustion engine contains a double-sided cordus 1 with an output end 2 communicated with the turbine 3 of the charge unit and the inlets 4 located on the side of the case 1. The inlets 4 are in communication with each of the cylinders. The cross-section of the nozzles on the collector side is smaller than its cross section on the cylinder side and their ratio is 0.3-0.8, preferably O, 4-0.5. Case 1 is made of constant diameter. The diameter of the body is 0, 3-0.5 of the diameter of the bore of the engine cylinder. The body consists of connected, disconnected, 5 segments, centered along the axis. To ensure the connection of two segments 5, annular ejectors 6 are provided. The body sections are integral with the inlets. The connection of the output end 2 of the housing 1 with the Turoin 3 is made using a spiral-shaped pipe 7. Pipeline 7 is of constant cross-section & In another embodiment, the pipe # 7 is linearly decreasing to zero. The conduit 7 is in the form of a full 360 spiral. In another embodiment, provided for a V-shaped engine & l, the coil with two entrances is connected to the outlets of both exhaust manifolds, and each input of the helix is connected to its own. collector. Depending on the order of ignition of the fuel-air mixture in the cylinders or their number, either two spirals are used, isolated from each other, or connected and interconnected. The pipeline 7 is made in the form of an armature & nbsp. Combustion of exhaust gases, after the strap from chipping pins to nozzles 4, is potentially energy-intensive, which ensures a dramatic reduction in the output of populated seams of nozzles. This results in an increase in initial opposition in the nozzle, and the losses caused by the exhaust valve are reduced. Bypassing the effect of ejecta in the nozzle, the transfer of gases from the nozzle to the co-pector is accelerated by transforming the cava energy into energy of velocity. 1. () 8 5в6 Bpagotsar, reducing the cross-section of the connector, the flow rate of gases is echoed higher than the energy of the velocity is converted into energy by a diffuser placed at the turbine, which also reduces static crowding in the reflector and improves cleaning of cylinders.
