Description

The twin-tub outer combustion-ing engine

The utility model relates to a kind of architecture advances of twin-tub internal combustion engine.

Motor is the most common in our daily life, also is most widely used power plant, can be the conversion of heat into kinetic energy that oil inflame produced by it.No matter be Motor Vehicle, the train that runs on the ground, or steamer waterborne, aircraft in the sky all be unable to do without motor, we can say there is not motor, does not just have the modern traffic tool.The cylinder driving mechanism of motor is to adopt internal combustion mode driven plunger to produce power at present.Light mechanism by installing one in the cylinder and produce heat energy, heat energy is converted into thermal pressure makes piston do upper and lower to-and-fro motion, produces power thereby drive the flywheel running.Yet this internal combustion type cylinder produces carbon distribution easily in cylinder, causes piston and cylinder inner wall impaired, and cylinder is shortened working life.

The purpose of this utility model provides a kind of burning-point mechanism and is arranged on outside the cylinder, does not produce carbon distribution in the cylinder, and piston and cylinder inner wall are not impaired, thereby prolongs the cylinder twin-tub outer combustion-ing engine in working life.

The purpose of this utility model realizes by following technological scheme, that is:

The twin-tub outer combustion-ing engine comprises master cylinder, countercylinder, flywheel and eccentric wheel.Wherein, the interior space of major and minor cylinder is airtight, is provided with the Circulation pipe mutual conduction between major and minor cylinder, is equipped with piston in major and minor cylinder, fixedlys connected with piston rod in the bottom of each piston.Flywheel is fixed on the fulcrum, and an eccentric wheel is respectively established at the fulcrum two ends, respectively establishes an eccentric rod on eccentric wheel, and two eccentric rods are connected with an end axle of two swing arms respectively, and the other end of two swing arms is connected with the lower end axle of two piston rods respectively.

The utility model is outside the cylinder top, be equipped with burning-point mechanism and produce heat energy, make and produce hot gas pressure in the master cylinders, and the auxiliary steam cylinder piston promotes downwards and pushes a pressure to auxiliary steam cylinder through Circulation pipe at this moment, this moment auxiliary steam cylinder piston arrives upper dead center, this strand air pressure is sent into auxiliary steam cylinder, just in time piston is promoted downwards, and master cylinders makes superjacent air space become big because of piston moves down, pressure also reduces, therefore under the effect of flywheel rotator inertia, drive the major-minor steam-cylinder piston through connecting rod, thus produce two cylinder pistons on, following reciprocating action and make the flywheel persistent movement to produce driving force.

The utlity model has in simple in structure, the cylinder and do not produce advantages such as carbon distribution, long service life.

Fig. 1 is a structural representation of the present utility model.

1 is that master cylinders, 2 is that countercylinder, 3 is that flywheel, 4 and 5 is that piston, 6 and 7 is that piston rod, 8 and 9 is that radiating fin, 10 is that Circulation pipe, 11 and 12 is that eccentric wheel, 13 and 14 is that eccentric rod, 15 is that fulcrum, 16 and 17 is a swing arm.

The utility model is described in further detail below in conjunction with accompanying drawing.

The twin-tub outer combustion-ing engine comprises master cylinders 1, auxiliary steam cylinder 2, flywheel 3 and two eccentric wheels 11 and 12.Master cylinders 1 is airtight with auxiliary steam cylinder 2 interior spaces, and be provided with space in Circulation pipe 10 conductings two cylinders between major and minor cylinder 1 and 2, flywheel 3 center fixation are on a fulcrum 15, two ends at fulcrum 15 are fixed with eccentric wheel 11 and 12 respectively, on the eccentric position of the side of eccentric wheel 11 and 12, be respectively equipped with eccentric rod 13 and 14, eccentric rod 13 is connected with an end axle of 17 with swing arm 16 respectively with 14, and swing arm 16 and 17 the other end are connected with 7 lower end axle with piston rod 6 respectively.

Working procedure of the present utility model is outside the master cylinders top, be equipped with burning-point mechanism, effect makes master cylinders 1 inner generation hot gas pressure and piston 4 is promoted downwards to master cylinders to produce heat energy with this, the gas pushing that pushes away for 4 times bottom space because of piston promotes the piston in the auxiliary steam cylinder 25 downwards in Circulation pipe 10 enters auxiliary steam cylinder 2, utilize piston rod 6,7 rotate eccentric wheel 11 and 12, drive flywheel 3 through fulcrum 15, and auxiliary steam cylinder 2 inner carriers 5 upper space gases move down because of master cylinders 1 inner carrier 4, head room becomes ambassador's pressure and diminishes, the effect of inertia that while rotates because of flywheel 3, promote piston 5 in the auxiliary steam cylinders 2 through eccentric rod 14 by piston rod 7, again by the piston 4 in the piston rod 6 driving master cylinderses 1, the thrust of planting hot gas cycle thus and being produced, make the piston 4 and 5 in master cylinders 1 and the auxiliary steam cylinder 2 produce continuous pumping, utilize the piston rod 6 and 7 of major-minor cylinder 1 and 2 to make eccentric wheel 11 and 12 produce rotation, via fulcrum 15 flywheel 3 is rotated, and make the two-piston bar that relative sequential take place, be that piston 4 in the master cylinders 1 is when upper dead center, piston 5 in the auxiliary steam cylinder 2 is in, between the lower dead centre, and eccentric rod 13 is positioned at the top position of eccentric wheel 11, and eccentric rod 14 is in the neutral position of eccentric wheel 12, with this flywheel 3 is produced continuously and rotate, thereby produce driving force.
