RU2043524C1 - Axial internal combustion engine - Google Patents

Abstract

FIELD: engine engineering. SUBSTANCE: engine can change its compression ratio and kind of fuel owing to screwing-in or screwing-out of connecting rods from pistons mounted inside the cylinders provided over periphery parallel to the output shaft. One or several pairs of the opposite cylinders can be disconnected by way of valves mounted in the fuel pipe line between the controlled valves and nozzles. EFFECT: enhanced efficiency. 2 cl, 2 dwg

Description

 The invention relates to mechanical engineering, namely to internal combustion engines.

 Internal combustion engines are divided into carburetor engines that run on light fuel, and diesel engines that run on heavy fuel, i.e. a certain engine is designed for a certain type of fuel. In addition to this drawback of the internal combustion engine, due to the crank mechanism, they have significant dimensions, experience large lateral loads, leading to cylinder wear.

 Small-sized axial piston machines are known, according to the scheme of which an internal combustion engine is made. In these engines, the cylinders are arranged circumferentially parallel to the shaft, the piston rods of which are connected with the inclined shaft washer.

 An internal combustion engine is also known, comprising a housing, cylinders, an output shaft, the axis of which is parallel to the axes of the cylinders installed in them with the formation of a piston working and piston compressor chambers of the piston and with check valves and channels, piston rods, a mechanism for converting the movement of pistons into rotation of the output shaft cam discs mounted on the shaft, fuel supply system.

 However, any type of fuel cannot be used here because of the constant compression ratio.

 The purpose of the invention is the expansion of the range of fuel used in the engine and increase its efficiency.

 This is achieved by the fact that in an axial internal combustion engine containing a housing, cylinders, an output shaft, the axis of which is parallel to the axes of the cylinders, pistons with check valves and channels, piston rods, a piston movement conversion mechanism are installed in them to form a piston working and piston compressor chambers in the rotational output shaft, cam disks mounted on the shaft, fuel supply system, the engine is additionally equipped with plunger fuel pumps with fuel lines and nozzles, with than controlled valves are installed in the fuel lines, the movement conversion mechanism is made in the form of an inclined disk rigidly connected to the output shaft, pistons with rods are connected by a threaded connection, and by the output shaft, pistons and rods are connected by a threaded connection, and purge rods are made in the piston rods channels, while nozzles for supplying water are installed in the piston chambers.

 In FIG. 1 shows a cutaway engine; in FIG. 2 detailed diagram of the cylinder block.

 The engine contains cylinders 1 with pistons 2, the rods 3 of which are pivotally connected to a washer 4 acting on the inclined disk 5 of the output shaft with the flywheel 6. A disk 7 with a cam for driving a water plunger pump 8 with an nozzle 9, a disk 10 for a drive are installed on the output shaft the cam of the fuel plunger pump 11 with the nozzle 12 and the disk 13 for driving the cam of the exhaust valve 14 to exhaust the exhaust gases into the exhaust pipe 15. The rod 3 with the piston 2 have a common channel 16 with a check valve 17. The engine contains an air duct 18 with a check valve 19 and candles plugs 20.

 The engine operates as follows (see figure 2).

 In the under-piston working chamber of cylinder 1, the working mixture is ignited, and the under-piston compressor chamber is filled with air, at this time the exhaust gases are discharged from the under-piston working chamber of cylinder IV and the air-water mixture enters it from the compressor chamber. At the same time, a working cycle is going on in cylinders V and VI, and a compression cycle is in cylinders II and III, with "B" the beginning and end of the water supply, "T" the beginning and end of the light fuel supply. In diesel mode, fuel enters the compressed air-water mixture.

 Controlled water and fuel flows to plunger pumps 8 and 11 are controlled by controlled valves 21 and 22. Solenoid valves (not shown) are installed between controlled valves 21 and 22 and plunger pumps 8 and 11 to shut off one or several pairs (opposite to each other) cylinders, and the compression ratio is changed by screwing or unscrewing the rod from the piston.

 The invention will improve the efficiency of vehicles.
