Description

3 / (

Internal combustion engine.

The claimed device relates to heat engines, namely to internal combustion engines operating with fuel injection and can be used, in particular, as transport engines.

Known internal combustion engines with a liquid cooling system in which the heat removed from the cylinder liners and cylinder heads by means of a liquid entering the external cooling system is then dissipated into the environment by means of radiators and a TOjtja / Shestopalov fan. , Dem1 ovsky S.F.Legkovsh cars ,, M., DOSMF, 1969

In the well-known engine, the cooling heat is not further used and 6e3B03BjjaTHO is in the surrounding atmosphere

the closest to the claimed technical solution is an air-cooled engine containing an external ribbing of sleeves and cylinder heads cooled by air with the help of a fan / Volkov AoT, repair of scooters, p. 240 .M., Engineering, 1987 /.

A common disadvantage of limestone engines is the irrevocable nature of the cooling heat loss, as well as the power loss w drive the fan included in the cooling system.

The proposed solution is aimed at eliminating these shortcomings.

combustion kashra, with a piston in it, as well as a camshaft kinematically connected to the rotor shaft, the air supply system to the combustion chamber and exhaust gas removal, as well as the fuel injection system, are performed with internal cooling, for which heating surfaces are used as cooling surfaces, limiting the volume of the combustion chamber, and which at the same time is performed identically insulated from the remaining parts of the engine, and the engine shaft and the drive of the injection system of the noodles / shaft of the high pressure pump / are kinematically connected with another way so that for one or several working 15x cycles with air supply to the exhaust and flush chamber alternating with one or several cooling flaps, in which only air is supplied to the combustion chamber without flashing, so that the same surfaces are used for working cycles are heated, and for each Cooling cycle - cooled.

The essence of the utility model is illustrated by the drawings: Fig. 2 shows a scrub view of an internal combustion engine / side view /, Fig. 2 shows a sectional view of Fig. 2 / image is enlarged /.

The internal combustion engine contains jerpus I, in which at least one combustion chamber 2 is located, with porin 3, and also an engine shaft 4 kinematically connected to the piston 3, mainly a crank mechanism / not shown /. The drive / shaft / 5 of the injection system of the noodles and high pressure pump / is connected to the shaft 4 of the engine mainly by a gearbox 6, made with remote manual or electric control, or automatic, changing the ratio of working and cooling cycles depending on the load or on the degree of heating of the combustion chamber, the heat-absorbing surfaces 7 / they are also cooled /, limiting the volume of the chamber 2 are thermally insulated / mainly completely / from the remaining parts of the engine with a heat-insulating layer 8, for example, ceramic. In this case, the combustion chamber is equipped with a nozzle 9 for fuel injection, and is also preferably equipped with a spark plug / not shown /

days to facilitate starting a cold engine. The combustion chamber njmwilo is equipped with at least one valve Yu and purge windows II, which, depending on the embodiment, can be either inlet or outlet. Shk is a variant of execution, a combustion chamber is possible only with kdashnmi - inlet and outlet, or its execution only with purge windows without valves. The engine can also be performed in the case where the fuel pump shaft has a constant kinematic connection with the engine shaft, so that their angular velocities are constant with respect to each other and the alternation of working and cooling cycles is preserved regardless of the load and heating of the combustion chamber.

The engine can also be made in the variant when the change in the ratio of working and cooling cells is carried out using a variator, for example electronic, which is part of the fuel supply system. The claimed engine can have a different number of combustion chambers, and mainly all KaMepi combustion in it is performed with thermal insulation of surfaces that limit their volume.

The internal combustion engine operates as follows.

When starting a cold engine, the hot mixture, which is dispersed in 1Sh. combustion 2 due to the mixture of air and fuel injected through the nozzle 9, is mainly ignited by the spark plug, designed to facilitate starting. When S1CH) we are vulnerable to the working mixture, it expands and the stroke of the piston 3, the reciprocating movement of which is converted in the engine into a satisfying drive shaft 4 of the engine. In this case, the shaft 5 of the high-pressure fuel pump receives from the shaft 4 of the engine through the gearbox 6 the angular velocity corresponding to the angular velocity of the shaft 4 so that the fuel is injected through the nozzle 9 mainly at each crack / at the end of the cycle with cathy /, so that cycles during the heating of the combustion chamber are predominantly working. As the working mixture is combusted during the working cells, the heat-receiving surfaces 7 of the combustion chamber 7 are quickly warmed up, the heat sink to the outer parts of the engine is heated, which has a larger heat capacity, heat insulation is prevented,

layer 8. After starting and warming up the combustion chamber 2, the engine mainly works without a spark plug / with ignition from

compression /, depending on the load of the engine or on the tedious part of the combustion chamber, the gearbox can transfer the fuel injection system / shaft / 5 to another angular velocity, i.e., change the ratio of alternating working and cooling cycles in the combustion cassette. The option option allows the engine to operate with a rigid, unchanging alternation of working and cooling cells, regardless of the degree of heating of the combustion chamber and the load of the engine.

The use of the internal cooling method in the inventive dvshtel makes it possible to obtain additional useful work without additional fuel costs by disposing of the cooling mash during cooling cycles, when air without fuel supplied to the combustion chamber is heated from surfaces that limit its volume, reducing the heat accumulated during working cycles, and expanding, pushes the piston down, doing useful work without additional fuel consumption.

In this case, the cooling of the combustion kernels occurs without additional loss of monstrosity to the fan drive, and, as a result, the engine power increases further due to cancellation of losses to the fan drive, in addition, when using the inventive engine, it is easier to start it in the cold season due to the low heat capacity of the heat surfaces of combustion chambers an additional useful quality of the claimed engine is also to reduce its weight and dimensions, due to the cancellation of all components and assemblies of the system external cooling, including a radiator and a fan.
