Description

The utility model relates to the field of engine building, in particular to devices for the formation of a combustible mixture of internal combustion engines, and can be used both for the modernization of vehicles in operation and in the development and production of new models.

It is known to use the heating of a combustible mixture [I.M. Lenin, O.M. Malashkin and others. Fuel supply systems for automobile and tractor engines. M .: "Mechanical Engineering", 1976] to increase the rate of evaporation of fuel and to compensate for the decrease in temperature that occurs due to heat consumption for the latent heat of vaporization. The intensity of heating the fuel mixture should not be the same for different fuels. The greater the latent heat of vaporization and the lower the vapor pressure of the fuel at a certain temperature, the stronger it is necessary to heat the combustible mixture. For heating, part of the heat that is carried away with the intake gases or transferred to the cooling system is usually consumed. In accordance with this distinguish between gas and liquid heating.

Known internal combustion engine [RF Patent 2002096, IPC F02M 31/087, z. 01/31/91., Op. 30.10.93.], Containing inlet and outlet pipes interconnected by a heat pipe with a capillary-porous structure and with an intermediate heat carrier, while an evaporator made in the form of an oval-shaped tube and equipped with a capillary-porous insert with an external plate is installed at the heat pipe inlet heat exchanger and is located in the exhaust pipe, and at the outlet of the heat pipe is a condenser made in the form of a chamber, the housing of which is connected to the wall of the inlet pipe with the formation of a liquid manifold-divider, p In fact, the outer surface of the chamber body facing the inlet pipe is corrugated and forms part of the inner surface of the inlet pipe, and the collector-divider is located in front of the corrugated surface along the intermediate coolant, and the chamber is connected via a tube to the evaporator.

Known manifold ICE [RF Patent 2262616, IPC F02M 31/087, s. 03/16/2004., Op. 20.10.2005.] Having a common flange for fastening to the engine, the exhaust pipes of which are connected to the flange for connecting to the exhaust pipe, and the suction pipes are connected to a receiving chamber equipped with a flange for connecting to a carburetor, while one of the walls of the receiving chamber is integral with walls of at least part of the exhaust pipes, and on the inner side of this wall in the receiving chamber there are fins of a heat radiator, the edges of which are guided by a deflector mounted on the inner edge of the carbide flange a jury.

As a prototype of the selected device for the formation of a combustible mixture of a carburetor engine [RF Patent 2280780, IPC F02M 15/02, 31/087, s. 01/31/2005., Op. 07.27.2006.], Containing a carburetor equipped with fuel-air channels and connected to the fuel line and air filter, inlet and outlet pipelines. A heat exchanger is located in the exhaust pipe, the inlet of which is connected to an air filter, for example, connected to a carburetor, and the outlet to the inlet pipe. The heat exchanger is equipped with a metering device, for example, a jet. A pipe connected to the inlet of the heat exchanger is connected to a fuel-air channel, for example, an emulsion well, while the pipeline is equipped with a metering device, for example, a nozzle.

The objective of the utility model was to create a device for the formation of a combustible mixture, making maximum use of the heat generated during engine operation, and, as a result, reduce environmental damage from engine operation, ensure uninterrupted operation of the engine on gasoline with a low octane rating, increase efficiency and increase engine life.

This problem is solved by a device for the formation of a combustible mixture of an internal combustion engine containing a fuel line, an intake and exhaust pipes and an exhaust heat exchanger as a heat transfer medium, the inlet of which is connected to an air filter, and the output to an inlet pipe, in which, according to the proposal, the inlet and exhaust the nozzles integrated into the collector assembly are partially made with a common wall (for example, in the form of a heat radiator or as a “pipe in pipe” type), and the heat exchanger is made in the form of a sealed to Zhuhai around the exhaust pipe and collector assembly, wherein the cavity of the heat exchanger formed by the housing, adapted to joining the pipeline from the breather.

The utility model is illustrated by drawings.

Figure 1 shows a possible implementation of a heat exchanger.

The device for the formation of a combustible mixture of an internal combustion engine contains a collector assembly 1, a fuel pipe 2, an intake 3 and an exhaust pipe 4 and a heat exchanger 5 in the form of a hermetic casing 6 around the exhaust pipe 4 and a collector assembly 1. The cavity of the heat exchanger 5 formed by the casing 6 has a pipe 7 ( inlet) that is connected to an air filter (not shown). The exit from the cavity of the heat exchanger 5 is connected directly to the inlet pipe 3. The inlet 3 and exhaust 4 nozzles combined in the collector assembly 1 are partially made with a common wall 8 in the form of a heat radiator (for better heat transfer, the wall can be finned on one or both sides) . The cavity of the heat exchanger 5 formed by the casing 6,

made with the possibility of connecting the pipeline from the breather (not shown) through the pipe 9.

The device operates as follows.

When the engine starts, all the air for the formation of a combustible (air-fuel) mixture passes through the heat exchanger 5, heating up from the exhaust gases. The heated air enters directly into the inlet pipe 3 and then to the mixture formation. Additional heating of the air occurs due to heat transfer through the wall 8 of the collector assembly 1, and also due to the supply of hot air to the cavity of the heat exchanger from the crankcase through the breather. The temperature control of the heated air and temperature control can be implemented in manual, semi-automatic or automatic mode. The claimed technical solution can be applied both to carburetor and injection engines.
