(57) Abstract:Usage: in industry, in particular in the engine, starting systems for internal combustion engines. The inventive starting system consists of an electric starter, the United electrical circuit with the battery, equipped with a Stirling engine connected with the output shaft of the internal combustion engine, and a thermal battery, made in the same block as the cylinder of the Stirling engine and connected with the exhaust gas of the internal combustion engine via a heat pipe, and an electric motor connected to the output shaft of the Stirling engine, for heating the heat accumulator after a long hiatus in the operation of the internal combustion engine it is equipped with a burner. The invention provides: improving efficiency and reducing emissions of toxic substances into the atmosphere and the net power of the battery by turning off the internal combustion engine during short stops of the vehicle or off the consumer and re-start of the internal combustion engine is a Stirling engine instead of an electric starter. 1 C.p. f-lmam start internal combustion engines.The famous design of the Stirling engine heat accumulator consisting of a Stirling engine connected to a heat pipe with thermal battery rechargeable from a gas burner or an electric heater (D. Makert. Stirling Engines. /Abbr. Per. s angl. M. engineering, 1985, S. 307-313).The design provides the Stirling engine, but does not provide its relationship with the internal combustion engine by using heat of exhaust gases and the scroll of the crankshaft of the internal combustion engine is a Stirling engine.Known system electropunk internal combustion engine, consisting of starter, battery and chain starter (Rogovtsev C. L. et al. design and operation of vehicles. M. Transport, 1991, S. 161).The described system does not allow frequent shutdown of the internal combustion engine due to a sharp reduction in resource rechargeable battery and starter for that reason. There is increased fuel consumption and the emission of toxic substances into the atmosphere during short stops of the vehicle or to disconnect customers and the engine is of the internal combustion engine at start-up requires you to use a powerful electric starter and a battery of large capacity.The purpose of the invention to improve economy, reduced emissions of toxic substances into the atmosphere and the required capacity of the battery.This objective is achieved in that the starting system consisting of an electric starter, the United electrical circuit with the battery, equipped with a Stirling engine connected with the output shaft of the internal combustion engine, and a thermal battery, made in the same block as the cylinder of the Stirling engine and connected with the exhaust gas of the internal combustion engine via a heat pipe, and an electric motor connected to the output shaft of the Stirling engine. At the same time for heating the heat accumulator after a long hiatus in the operation of the internal combustion engine it is equipped with a burner.Distinctive features of the invention are the following:
the use of the Stirling engine to scroll the output shaft of the internal combustion engine;
performing a thermal battery in one unit with the cylinder of the Stirling engine;
the transfer of heat from the exhaust gases of the internal combustion engine to heat the battery by means of a heat pipe;
Primero combustion.The application of the described system engine start allows frequent shutdown of the internal combustion engine at all, even briefly stops the vehicle or disconnect customers, and re-start of the internal combustion engine be done by scrolling output shaft of the Stirling engine to the heating of the working fluid from the heat accumulator, since the Stirling engine is turned off only when long-term Parking of vehicles or disconnect customers and provides a quick re-start of the internal combustion engine without using the starter and battery. However due to the exclusion of the operation of the internal combustion engine in the idling mode increases efficiency and reduced emission of toxic substances into the atmosphere. Because the Stirling engine has a small resistance scrolling output shaft and starts only after a long hiatus in the operation of the internal combustion engine requires a starter low power to start, and it becomes possible to reduce the required capacity of the battery.Heating of the heat accumulator after a long break in the engine vnutrennyaya.The drawing shows a diagram of the system start the engine.Starting system of the engine 1 internal combustion engines equipped with a Stirling engine 2, the output shaft 3 which is connected with the output shaft 4 of the engine 1, the internal combustion through the clutch 5 free play. The head 6 of the engine 2 Stirling executed in the same block as the heat accumulator 7, which by means of the heat pipe 8 is connected with the exhaust gas line 9 of the engine 1 internal combustion engines. To start the engine 2 Stirling it has an electric starter 10, connected to an electric circuit 11 and the battery 12. For heating the heat accumulator 7 after a long break in the engine 1 of an internal combustion installed the burner 13.When the starter 10 he uses the Stirling engine 2, which provides start-up of the engine 1, the internal combustion through the freewheel clutch 5 connecting the output shafts 3 and 4 of the Stirling engine 2 and the motor 1 internal combustion engines.When the engine 1 is an internal combustion heat of the exhaust gas is transferred from the exhaust gas line 9 to heat the battery 7 through the heat pipe 8 and heats it. Thermal ACC is Shui Autonomous operation of the engine 2 Stirling. After starting the engine 1, the internal combustion engine speed output shaft 4 exceeds the rotational speed of the output shaft 3 of the engine 2 Stirling and the freewheel clutch 5 separates these shafts.During short stops of the vehicle or disconnect customers engine 1 internal combustion shuts down and stops feeding it fuel and the emission of toxic substances into the atmosphere. While the Stirling engine 2 continues to work with due to heat accumulated in the heat accumulator 7. Re-start of the engine 1, the internal combustion is effected by switching on the clutch 5 free running.During cooling of the heat accumulator 7 after a long break in the engine 1 of an internal combustion heat of the heat accumulator 7 before starting the Stirling engine 2 is produced by the burner 13 working on the fuel used in the engine 1 internal combustion engines.Described starting system engine allows to increase the efficiency and reduce the emission of toxic substances into the atmosphere, as during short stops of the vehicle or the disconnection of the consumer stops the fuel supply to the engine internal share the ü multiple re-starts of the internal combustion engine without using the starter and the battery, moreover, the operation of the internal combustion engine after each start replenishes the supply of heat in thermal battery. Performing a thermal battery in the same block as the cylinder Stirling engine allows to reduce heat losses during transmission to a working body of the Stirling engine. Application of heat pipes to transfer heat from exhaust gases in the exhaust gas of the internal combustion engine to heat the battery improves the layout of the internal combustion engine without increasing heat loss when filing its between these devices. A small moment of resistance of the Stirling engine at start-up allows you to use the starter low power and reduce the battery capacity. Built-in heat accumulator burner provides heating of the heat accumulator and the start of the Stirling engine after a long hiatus in the operation of the internal combustion engine.Thus, the use of the system, start the engine, described above, gives the starting system of the engine of new design features, unknown from other technical solutions. These features consist in the fact that to scroll the output shaft of the internal combustion engine applied diheteropogon internal combustion engine through a heat pipe and is equipped with a burner. This in turn allows to increase the efficiency and reduce the emission of toxic substances into the atmosphere and the required capacity of the battery by turning off the internal combustion engine during short stops of the vehicle or the disconnection of a customer and re-start of the internal combustion engine is a Stirling engine instead of the electric starter, and thus to achieve the purpose of the invention. 1.
