Abstract
Quick ignition gasoline engine of new practical and compact type is to develop to form on the basic theory of existing compact rapid burning petrol engine, and existing compact rapid burning petrol engine is owing to failing to break away from the interference of detonation, so still also rest on the experimental study stage so far.The present invention is at piston top system one boss, at recess of cylinder cap bottom system.The two is approaching mutually when piston walks to the summit, makes the passage attenuate between firing chamber and the air-cushion gap, reduces the interference of burnt gas to unburned mixture, disturbs thereby make quick ignition gasoline engine of new practical and compact type can break away from detonation, enters the practical stage.
Description
The invention relates to the design of gasoline engine combustion chamber
The present invention is that my improvement of preceding " practical compact rapid burning petrol engine " invented (application number 89109083.5, the applying date 19891204, the former machine of following abbreviation) newly designs, so be called " quick ignition gasoline engine of new practical and compact type." (being called for short the present invention or this machine down).
The structure of the present invention and former machine has little change, except that the advantage that still keeps former machine, also has new advantages such as processing technology simplification and firing effect improvement.Still can be under former machine service condition, or use under the condition of slight change.
This machine is with former machine something in common: boss is all arranged at their cylinder cap bottom, and their piston head all has recess, and with machine boss height and recess deep equality separately.Their differences are: the height of this machine boss, recess, deeply all than former machine boss, recess profundity, less.
Fig. 1 is the section of former machine piston when last summit, and at this moment its firing chamber (A) is spaced from each other with air-cushion gap (B), not exchanges information.Fig. 2 is the section of this machine piston when last summit, and at this moment firing chamber (A) is still with air-cushion gap (B) and communicates, and just the thickness h of the passage between the two is more slightly smaller than the thickness t of its air-cushion gap (B).Because former machine (A), (B) separate fully, (A) raising of the temperature and pressure of internal combustion generation does not make a difference to (B) interior mixed gas, takes place in (B) so can prevent detonation.And in this machine, (A) though with (B) separate, but the thickness of passage is less, so (A) raising of the temperature and pressure that takes place of internal combustion, only (B) interior mixed gas is produced less influence, so also still have the performance that prevents that detonation from taking place in (B).The two is compared, and the former explosion-proof performance is stronger, latter's explosion-proof a little less than.But under certain situation, (refer to octane value, the speed of gasoline and make altitude of land used or the like), the two may all be suitable for; And only be suitable for a certain machine in another situation.That is to say the two applicable scope some difference slightly.
This machine has reduced the degree of depth of recess on the height of cylinder cap lower convex platform and the piston head, thus when piston during on last summit, the two and unlike former machine mutual contract go into, be separated from each other and be still; So also unlike former machine, the two problem that cooperatively interacts.This just can reduce the machining accuracy of boss and recess limit wall, simplifies technology, and this is first advantage of this machine.
Second advantage of this machine is: the height and the degree of depth of cylinder cap boss and piston recess have reduced, and good heat dispersion performance is favourable to avoiding abnormal focus, surface ignition, therefore can improve firing effect.
From above-mentioned two issuable good effects of advantage be: 1, simplify technology, reduce manufacture cost; 2, improve firing effect, reduce fault, improve the thermal efficiency.
Description of drawings two:
(Fig. 1) is the section of former machine, and (Fig. 2) is the section of this machine, and (A) is the firing chamber among two figure; (B) be air-cushion gap.
T is the thickness of air-cushion gap, generally can adopt t=1.2mm.H is the thickness of piston passage between firing chamber (A) and the air-cushion gap (B) when last summit, t＞h 〉=o, and the optimal selection of h must be by the test decision.
This machine-processed making process and former machine and regular price gasoline machine and indistinction.
The boss under the cylinder cap and the recess of piston head, neither contract is gone into mutually, and the limit wall of the two can be made with casting method, does not need machining, and just the boss top should be slightly larger than recess, and the two outerplanar then needs accurately processing.
The same with former machine, boss on cylinder cap and the piston and recess can exchange.
Claims (1)
- Quick ignition gasoline engine of new practical and compact type is to form from the present theoretical foundation development that still rests on the fast quick burning petrol engine of compact type of experimental stage.The theory of compact rapid burning gasoline is the disclosed public wealth of world academia.The invention is characterized in:1, an ellipse garden shape boss is arranged at the cylinder cap bottom, and its height is less than the cushion depth t of piston when the last summit.[consulting Fig. 2].2, piston head has a recess, and its shape, the degree of depth are identical with shape, the degree of depth of cylinder cap convex platform.Just the outer stupefied size of recess can be slightly smaller than boss 1mm.3,, get close to minimum dimension h at the top of boss and recess during on last summit at piston according to claim 1,2 described petrol engine.4, according to claim 1,2,3 described petrol engine, the recess of its piston head and cylinder cap bottom and the position of boss can exchange.5, according to claim 1,2,3,4 described petrol engine, can be by the new quick ignition gasoline engine of new practical and compact type of its principle design manufacturing; Also can be transformed into this novel petrol engine, need only change a small amount of other component of cylinder head and piston during transformation by its principle regular gasoline machine that present aircraft, automobile or the like is used.
