Facilitate engine start-up by reducing warm-up time by bringing in: and exhaust pipes made in the form of heat pipes equipped with thermal valves. .

Description

2. A device according to claim 1, wherein the first exhaust pipe is connected to the engine fuel injection system.

3. The device according to PP.1 and 2, differing from the fact that the second

The exhaust pipe is connected to the engine cooling system.

4. A device according to claims 1-3, in which one third of the exhaust pipe is connected to the engine oil system.

The invention relates to mechanical engineering, in particular to internal combustion engines, and can be used in devices for providing start-up with heated engine fluids. Devices are known for heating fluids in systems of internal combustion engines / containing a heat accumulator connected by means of an inlet pipe to an exhaust manifold of the engine and by means of exhaust pipes with engine systems l 1. The known devices allow the engine to be started at low temperatures. However, due to the fact that a coolant with a low specific thermal load is used in the battery / these devices are ineffective. . . . It is also known a device for heating fluids in engine systems of an internal combustion engine, which contains a heat pump and a solid heat carrier accumulator, connected by means of an inlet pipe with a single-throttle motor mainline and by means of exhaust pipes - with systems (Engine,. . The known device allows the engine to be started at low temperatures with high efficiency 2. A disadvantage of the known device is the difficulty of starting the engine with it, since the low heat transfer rates The purpose of the invention is to facilitate the start-up of the heater by shortening the warm-up time. To achieve this goal in a device for heating fluids in internal combustion engine systems containing a heat exchanger with a solid heat transfer fluid connected by means of an inlet pipe with an engine exhaust line and by means of outlet pipes - with engine systems; the inlet and outlet pipes are made in the form of heat pipes equipped with thermal valves; va retraction conductive pipe may be connected to .toplivopodachi engine system. A second exhaust pipe may be connected to the engine cooling system. A third exhaust pipe can be connected to the engine oil system. Figure 1 shows a device for heating fuel in an internal combustion engine; figure 2 - node I in figure 1; Figs - a device for heating the coolant and oil in an internal combustion engine; Fig.4.5 - nodes And 111 and Fig.Z, respectively. The device contains. heat accumulator 1 with solid t: a heat carrier 2 / placed in the heat insulator 3.-Heat. The accumulator 1 is connected by means of a supply heat pipe 4c to the exhaust line 5 of the engine. In the supply pipe 4, the heat- is installed: - VOY valve b, intended for one-sided heat supply K accumulator-; To the heater 1. The exhaust heat pipes 7-9, the accumulator 1 is connected to the engine systems. The first exhaust pipe 7 is equipped with a thermoelectric valve 10, connected to the system 11. fuel injection engine. The second exhaust pipe 8 is connected via a thermal thermoelectric valve 12 to the engine cooling system 13. The third exhaust pipe 9 is connected via a thermal thermoelectric valve 12 to the engine oil system 14. To maintain the optimum thermal conditions of the coolant and oil, the thermal valve 12 is coupled back to thermal sensors 15 located in the oil system and in the engine cooling system. . During engine operation, part of the exhaust gas flow is supplied through the supply heat pipe 4 and the heat valve b, which allows heat in one direction only, to the heat accumulator 1. Heat

accumulates in solid coolant 2.

Before starting the engine, it opens thermal thermoelectric valves 10 and 12, and heat through exhaust heat pipes 7-9 goes to the engine systems, carried out In them in a short period of time

heating fluids to the temperatures required for starting and subsequent operation of the engine internal combustion.

Thus, as a result of the use of heat pipes, it is possible to finish off, with the ease of starting the engine inside the early fire by reducing its warm-up time.fpu3 .l
