    An exhaust port liner for an internal combustion engine is formed of thin wall heat resistant material and is provided with an entrance opening at one side to receive exhaust gases discharged from an engine combustion chamber. A poppet type valve which closes against a stationary seat has a portion which extends through the entrance opening of the liner and also through an aperture in a wall of the liner. This aperture may also receive a portion of the valve stem guide and the liner may be fixed to the valve stem guide in the region of said aperture. The liner has a discharge opening and a support flange supporting the liner encircles the discharge opening. A peripheral layer of heat insulating material may be provided on the liner and this heat insulating material may be confined within a shell forming a part of the liner.

    (54) INTERNAL COMBUSTION ENGINE
    权利要求:
    Claims (5)
    [1]
    The invention relates to machine-control, in particular, engine-building, and more particularly to devices for cleaning the exhaust gases of an internal combustion engine. The well-known internal combustion engine contains a cylinder head mounted in it on a directional exhaust valve with a rod, its seat, an outlet channel connecting the combustion chamber to the exhaust manifold, and a thick-walled insert installed in the channel with a gap in relation to the walls and About izuylutsy with a nice ring of a woo u left. In the cell there is a seal to the head with the help of a flange placed in the junction of the head with the exhaust manifold and separating the annular cavity from the manifold. The ring overlap plays the role of a heat insulating layer between the flue with the channel and the walls of the head, and the thick walls of the liner are the accumulators of heat Cl Heat heat inertia of the heat sink | which does not allow for speeding up to the thermal afterburning mode of the exhaust gases.In addition, the thick walls of the liner block the channel cross-section and increase the exhaust resistance. The thin-walled liner eliminates the noted disadvantages. There are known internal combustion engines that contain a cylinder head, mounted thereon on an exhaust valve with a stem, its seat, an exhaust channel connecting the compression chamber with the exhaust manifold, and a thin-walled liner installed in the channel with a gap in relation to the walls and the annular cavity forming with NICKY. The annular cavity also provides thermal insulation of the liner and in its internal cavity thermal 3U8 reactions of exhaust gases f2 decrease occur. However, in known devices, the gap is open at the ends and, due to the circulation of gases through this gap, the efficiency of thermal insulation and reduction of toxicity is not high enough. The purpose of the invention is to reduce the toxicity of exhaust gases. To achieve this goal, the annular cavity is separated from the exhaust manifold by means of a partition, and on the opposite side is connected to the combustion chamber. The partition is made in the form of an annular flange attached to the liner and placed between the head and the exhaust manifold. The end of the liner facing the combustion chamber is made enveloping the valve stem, and on the opposite side of the butt side of the liner is made with a slot for accommodating the valve stem and is provided with a sealing partition, the liner and the partition are attached to the guide. The outer surface of the liner is partially covered with a layer of insulating material that can be encased in a casing. FIG. 1 shows the engine, a section through the exhaust valve; in fig. 2 However, for another embodiment of the design. The engine contains a cylinder head 1 with an exhaust channel 2 connecting the combustion chamber with an exhaust manifold. Channel 2 has an insert 5, which forms an annular cavity 6 with the walls of the channel. From the exhaust manifold k, cavity 6 is closed by a partition 7, which is an annular flange attached to the liner and placed between the head 1 and the exhaust pipe. G cavity 6 opposite to the TORON is communicated with the combustion chamber 3 through the annular irl 8. The outer surface of the liner is partially covered with a layer of thermal insulation material 9 encased in a casing 10. A valve seat 11 is installed in the valve. The liner facing the combustion chamber 3 encloses the valve stem 12 housed in the rail 13, and on the opposite side of the liner is made with a slot for accommodating a guide and provided with a sealing partition 1. Moreover, the liner and the barrier are attached to the rail 13. When the engine is operating, the exhaust gases flow from the combustion chamber 3 into channel 2 and further into the exhaust manifold. Part of the gases through slot 8 enters the annular cavity 6 formed by the walls of the liner and the channel. The continuous flow of exhaust gases maintains an elevated temperature in the cavity, which reduces heat transfer from the exhaust gas to the channel walls and increases the efficiency of the thermodynamic processes of exhaust gas neutralization. Claim 1. The internal combustion engine containing a cylinder head has an exhaust valve with a rod installed on it on the pilot, its seat, an exhaust channel connecting the combustion chamber with the exhaust manifold, and a thin-walled liner installed in the channel with a clearance relative to to the walls and forming with them an annular cavity, characterized in that, in order to reduce the toxicity of exhaust gases, the annular cavity is separated from the exhaust manifold by means of a partition, and on the opposite side, the price combustion measure.
