Abstract

A rolling-rotor engine with unequal volume ratio of composed of main body, compression cylinder, work-doing cylinder, fuel-air mixed, distributing system and combustion chamber. The said cylinders are composed of eccentric mandrel, rolling ring and isolating blade. The rotation speed of the said eccentric mandrel is equal to the cam axle in distributing system. The said mixer is communicated with compression cylinder. The said isolating blade in work-doing cylinder can block to channel between combustion chamber and work-doing cylinder whose exhaust hole is communicated with external air.

Description

Rolling-rotor engine with unequal volume ratio

The present invention relates to a kind of rotary engine, especially a kind of not isometric(al) compares rolling rotor type engine.

Traditional conventional engine, be divided into two-stroke and four-stroke two classes, two stroke engine is owing to adopt the gas port control gaseous to flow, therefore have fresh air and just discharge cylinder without burning, influence Economy, add that to start the effective travel of function work done shorter, so the working medium underexpansion, thermal power transfer becomes the efficient of mechanical energy low.Work cycle of four stroke engine will be finished air inlet, compression, work done and four strokes of exhaust, motor need rotate two commentaries on classics, reduced the speed of output work, simultaneously because in order to improve volumetric efficiency, the valve opening angle surpasses 180 ° of a stroke correspondence, also shorten effective travel, reduced efficient.

Conventional engine also has quality bigger piston, connecting rod reciprocating except the rotation motion of bent axle, and this has just increased frictional loss, has strengthened the noise of motor, environment is produced destroy.

Noise and excitement once so-called for the moment " triangle rolling-rotor engine ", also relatively poor because of its complex structure, manufacturability, that working medium expands is still not enough, operation energy consumption is high, efficient is low, and can't drop into practical application.

We once were called (application number: 98125738.0) in the application for a patent for invention of " a kind of rolling rotor type engine " in name, structural type and the roughly the same new-type rolling-rotor engine of patent application technology of the present invention were disclosed, though its performance is better than conventional engine, do not give full play to as yet but still feel its efficient.

Purpose of the present invention is to provide a kind of fuel thermal energy more to make full use of to the public, the new-type rolling-rotor engine of high working efficiency, stable working.

This neoteric rolling-rotor engine with unequal volume ratio, with number of patent application is that 98125738.0 " a kind of rolling rotor type engine " is the same, also be to be called " the hinged isolated blade rolling rotor compressor of double end " according to disclosed name before us (patent No. is: structural principle 98244743.4) has designed a class compression cylinder and a class work-doing cylinder for the basis.Be that neoteric rolling-rotor engine with unequal volume ratio is by the compression cylinder that is fitted on the cylinder body, work-doing cylinder, fuel-air mixer and gas distribution system and firing chamber constitute, compression cylinder is by eccentric mandrel and is sleeved on rolling ring on the eccentric shaft rank of eccentric mandrel, and two ends portion hinged respectively be fitted on the casing wall and the rolling ring outer wall on isolated blade form, work-doing cylinder also is by eccentric mandrel and is sleeved on rolling ring on the eccentric shaft rank of eccentric mandrel, and two ends portion hinged respectively be fitted on the casing wall and the rolling ring outer wall on isolated blade form, gas distribution system is by camshaft; rocking arm; valve and valve spring are formed; be equipped with spark plug on the wall of firing chamber; its technical characterstic just is: the eccentric mandrel of compression cylinder; the rotating speed of the camshaft in the rotating speed of the eccentric mandrel of work-doing cylinder and the gas distribution system is identical, to guarantee mutual work phase stabilization.The suction tude of fuel-air mixer is communicated with the inlet hole of compression cylinder, port is arranged on the air flue at place, isolated blade pit top on the compression cylinder body wall, through valve be arranged on cylinder body and cylinder cap on the firing chamber connection that the cavity sealing forms that links to each other, fuel and air mixing are after after the compression cylinder compression, promptly inject the firing chamber by valve opening, in work-doing cylinder, when isolated blade is positioned at eccentric mandrel rotating center apart from maximum, isolated blade is the port that firing chamber and work-doing cylinder passage in shutoff, and the port that the compression cylinder air flue feeds the firing chamber in the valve shutoff, at spark plug to entering after fuel in the firing chamber-air Mixture igniting makes it explosive expansions, it is the isolated blade of roof pressure work-doing cylinder, drive eccentric mandrel rotation, the exhaust port of work-doing cylinder on cylinder body is communicated with atmosphere, and the waste gas after the work is promptly discharged from exhaust port.

This new-type rolling-rotor engine is to utilize isolated blade and rolling ring that clutch release slave cylinder is divided into two zones: compression cylinder is divided into air-breathing and compression chamber, work-doing cylinder are divided into work done and exhaust space, and its structure is much simpler than general reciprocating-piston engine and rotary polygonal piston engine; Speed of related movement between rolling ring and the casing wall is lower, and mainly be rolling friction, isolated blade is also just done simple swing betwixt, so the frictional loss between moving parts is far smaller than the motor of other pattern, and since because of its part movement speed low, inertial force is little, stressed also little, so the whole aircraft reliability height is difficult for producing fault; Moreover its sealing surface substantially all is to be plane, very easily in implementing sealing, is beneficial to assembling, keeps in repair; The combustion explosion of fuel-air Mixture is to carry out in the airtight firing chamber that the cavity that linked to each other with cylinder cap by the cylinder body that valve, isolated blade sealed forms, so the combustion efficiency height, cylinder hole inwall is influenced by heat less, and working condition is stable; Because equaling volume between cylinder hole and the rolling ring, the allowance for expansion ratio adds 1 divided by the merchant of combustion chamber volume, add 1 divided by combustion chamber volume with the merchant who is connected air flue volume sum greater than volume between cylinder hole and the rolling ring, promptly form so-called not isometric(al) ratio, and burning back gas temperature raises a lot, the merit that external output work is absorbed when gas is compressed so gas expands, the external output work of motor.

Below in conjunction with accompanying drawing specific embodiments of the present invention is described in detail:

Fig. 1 is a general structure schematic representation of the present invention;

Fig. 2 is a kind of scheme schematic representation of eccentric mandrel interlock situation of camshaft of the present invention and compression cylinder, work-doing cylinder.
