Abstract

A compressed air engine is an engine using compressed air as power and comprises a cylinder head cover provided inside with a piston and a piston connection rod. The piston connection rod is connected with a crankshaft, a speed varying means, and a transmission means in order. A cam shaft assembly is further arranged inside the cylinder head cover. One end of the cam shaft of the cam shaft assembly is connected with a bearing and the other end is connected with a bearing and a timing wheel. A rounding cone air outlet cam and an air outlet cam are arranged in the middle part of the cam shaft. An air inlet port of the cylinder is communicated with an air pipe of an air tank. The air tank is further provided with an air feed port, a control valve, an air pressure meter, and a timing valve. The utility model defines the ignition time of the four-stroke gasoline engine (100 type) as air inlet time and utilizes the compressible air as power, and has the advantages of reduced energy consumption, no environmental pollution, low noise, no need of carburetor, no failure of electronic ignition, easy start-up of engine, no influence of temperature and weather, no risk of power reduction due to overheat of engine, long service life, and less wearing of parts. The compressed air engine is novel and has large potential.

Description

Air compressed engine

Technical field

The utility model relates to a profit and utilizes the dynamic power machine of pressurized air for power.

Background technique

Power cars such as automobile use gasoline for the fuel, and it is in short supply that the present world faces fuel oil, and fuel price goes up, and can not satisfy the situation of the needs of fuel oil.The problem that oil inflame is bigger is a befouling environment, and for addressing the above problem, some countries utilize ethanol to come gasoline replacing, have obtained some effects, and still, the gas of ethanol behind cylinder combustion is not pollution-free, and the ethanol price is than gasoline height.So there is the people to consider to use the motor of pressurized air left side power, as " a kind of air engine " (patent No. 93119756), comprise gas holder, power take-off and the supplementary device of calming the anger, gas holder is installed on the base, its steam outlet pipe is communicated with the suction chamber of power take-off, power take-off is connected with the supplementary device of calming the anger by the drive wheel in the powered pulley and the supplementary device of calming the anger, and air outlet adapter one end of the supplementary device of calming the anger is communicated with the gas holder inlet hole.Reach the purpose of speed change with varying in size of wheel, its energy consumption is big." air engine " (patent No. 9710672), battery pack is connected with air compressor, solenoid valve, generator by lead, switch, air pipe is affixed by barometric damper, air valve, solenoid valve and cylinder, piston is by connecting rod and crank (flywheel) socket, driving wheel, cam are affixed by bent axle and crank (flywheel), and driving wheel is in transmission connection by belt (or gear) and generator follower.

The cam assembly structure of former 100 type four-stroke gasoline engines as shown in Figure 3, camshaft 15 1 end connecting shafts hold that 14, one end connecting shafts hold 18, positive hour wheel 19, middle exhaust cam 16, intake cam 17 are half cone-shaped.When the round dot of positive hour wheel 19 pointed to timing points, plug ignition started, air inlet, exhaust valve closing, the long 97mm of cylinder.

Summary of the invention

The purpose of this utility model aims to provide that a kind of energy saving, non-environmental-pollution, noise are little, motor is difficult for heating, no ignition failure, easy startup, not influenced by temperature, weather condition, long service life, the air compressed engine that parts wear is slow.

The implementation of the utility model purpose is, air compressed engine, cylinder 3 has cylinder skull 1, in piston 2, piston rod 4 are arranged, piston rod 4 connects bent axle 5, gear 6, transmission part 7 successively, in the cylinder skull 1 cam assembly is arranged, the camshaft 15 1 end connecting shafts of cam assembly hold 14, one end connecting shaft holds 18, positive hour wheel 19, camshaft 15 dress full circle taper exhaust cams 16, intake cam 17, the suction port of cylinder 3 is communicated with the pneumatic tube 13 of gas holder 10, and gas holder 10 is equipped with valve 12 when adding gas port 9, control valve 8, barometer 11, control.

The utility model is identical with 100 type four-stroke gasoline engines basically from form, outward appearance, size, volume, internal structure, but because of being power with pressurized air, so following change is arranged:

1, will change period of intake firing time into;

2, cylinder body increases 2-3mm, in order to avoid the valve that bump is opened;

3, removed spark plug, high pressure packet, igniter, spark coil, trigger relay, Carburetor etc., simple in structure.

The utility model energy saving, non-environmental-pollution, noise are little, do not have the electronic ignition fault, without Carburetor, Fuel Petroleum, motor easily starts, and not influenced by the temperature weather condition, does not more have the lack of fuel problem, there is not engine overheat power decline problem, long service life, parts wear wait advantage slowly, are that a kind of having a high potential has the new power machine of development and use.

Embodiment

With reference to Fig. 1, the utility model cylinder 3 has cylinder skull 1, in piston 2, piston rod 4 are arranged, piston rod 4 connects bent axle 5, gear 6, transmission part 7 successively, in the cylinder skull 1 cam assembly is arranged, the camshaft 15 1 end connecting shafts of cam assembly hold 14, one end connecting shaft holds 18, positive hour wheel 19, camshaft 15 dress full circle taper exhaust cams 16, intake cam 17, the suction port of cylinder 3 is communicated with the pneumatic tube 13 of gas holder 10, and gas holder 10 is equipped with valve 12 when adding gas port 9, control valve 8, barometer 11, control.

With reference to Fig. 2, the camshaft 15 dress full circle taper exhaust cams 16 of cam assembly of the present utility model, intake cam 17.When the round dot of the positive hour wheel 19 of valve 12 controls points to timing points during control, intake cam 17 backs down the intake valve of cylinder 3, pressurized air in the gas holder 10 enters in the cylinder, pressurized air promotes piston 2 to the lower dead center operation, and piston rod 4 spreads out of power by bent axle 5, gear 6, transmission part 7.When piston 2 ran to lower dead center, exhaust cam 16 backed down exhaust valve, and the gas in the cylinder skull 1 is discharged from exhaust valve 20, and piston 2 reversion are to top dead center, and promptly the round dot of positive hour wheel 19 points to timing points, finishes a working stroke like this.
