1484363 Pre-combustion chambers HONDA GIKEN KOGYO KK 10 Oct 1974 [11 Oct 1973] 43975/74 Heading F1B A spark-ignition I.C. engine comprises a precombustion chamber 21, Fig. 1, enclosed by a thin-wall stainless steel cup 22 and receiving a rich mixture from an auxiliary carburetter via an auxiliary intake valve 34. A residual-gas chamber 41 communicating with the chamber 21 via a restricted opening 43 contains the spark-plug electrodes 47 which are located near the opening 43 and remote from the end-wall 48 of the chamber 41. At the end of the exhaust stroke, residual exhaust gases remain in the main combustion chamber 16 and in the chambers 21, 41. During the subsequent induction stroke, lean mixture is admitted into the main chamber 16 and rich mixture is admitted into the chamber 21, fills it, and is drawn through flame passage 29 into the main chamber, where it forms a region of relatively rich mixture encompassed within a larger region of relatively lean mixture to provide a stratified charge. Little change occurs in the residual-gas chamber 41. During the compression stroke, the increase in pressure in the main chamber 16 causes reverse flow through the flame passage 29 and through the restricted opening 43, whereby the mixture in the chamber 21 becomes less rich and the residual-gas chamber contains a compressed mixture of air, fuel and residual exhaust gases, the concentration of residual gases being greatest near the end-wall 48. On ignition, a first flame jet carrying both burning and residual gases is projected from the residual-gas chamber 41 through the opening 43 to ignite the rich mixture in the chamber 21, producing high turbulence. A second flame jet is then projected through the flame passage 29 to ignite the stratified charge in the main chamber 16 and so ignite the main body of lean mixture in the main chamber. The axis of the opening 43 is out of alignment with the axis of the passage 29 so that the first flame jet does not pass directly through the passage, the electrodes 47 are not fouled by direct inpingement of a rich mixture jet during the compression stroke, and turbulence in the chamber 41 is minimized. The residual-gas chamber may have a thin-wall stainless steel liner which is surrounded by a clearance space which minimizes heat transfer so that the liner is kept hot. An existing type of stratified-charge engine may be modified by providing a member which screws at one end into the spark-plug hole and is hollow so as to constitute the residual-gas chamber, a special spark-plug screwed into the other end having long electrodes so as to bring the spark gap near the opening 43. The volume of the residual-gas chamber may be raised by means of a plug 83, Fig. 6, which is slidable within a bore by means of a rotatable sleeve 88 via a cam slot and pin arrangement 86. An actuator arm 89 is linked to the throttle pedal or to a diaphragm operated by the intake manifold vacuum.

I
The invention relates to the field of mechanical engineering, in particular, engine-building, and can be used in a pre-chamber internal combustion engine.
Famous internal combustion engines, containing a combustion chamber connected through a main valve to a pipeline for supplying a poor fuel-air mixture, a prechamber communicated through a bypass hole with a cavity in which a spark plug is dispensed and through auxiliary valve to a pipeline for supplying an ear-rich fuel carrying vehicle, and the mode indicator 1 1.
The volume of the cavity of the spark plug affects the content of nitrogen oxides in the exhaust gases of the engine, and the change in this volume is advisable to change during engine operation. It is advisable for children to create such an engine in which the volume of the cavity of the spark plug could be adjusted depending on the load in order to reduce the content of oxides in the exhaust gases.
The aim of the invention is to reduce the content of nitrogen oxides in exhaust gases by changing the volume of the cavity of the spark plug.
For this, a movable wall is placed in the cavity of the spark plug connected to the operating mode indicator.
FIG. 1 shows a section through an engine chamber and a combustion chamber, the movable wall being in the position where the volume of the cavity of the spark plug is the smallest; FIG. 2 is a cross-section of the cavity of the spark plug; FIG. 3 is a section through the prechamber, but the movable wall is in a position where the volume of the cavity of the spark plug is greatest in FIG. 4 — mechanism for adjusting the sliding position of the movable wall; in fig. 5 is a diagram of the change in vol. VP of the cavity of the spark plug depending on the engine load.
The internal combustion engine contains a combustion chamber 1 formed in cylinder 2 by its head 3 and piston 4. Combustion chamber 1 is connected through the main inlet valve 5 to pipe 6 for keeping the lean air-fuel mixture and through the flare channel 7 to the rear chamber 8. Chambers 8 communicated through the resetting hole 9 with a cavity in which the candle is located behind the iSraLril and placed movably made in the form of a plunger G12 which is connected via a cable and with a gauge of sensor operation; fi: - :: nir., SSS; „Г„ .. , „Nd mixture ™ great-Gd °: H„ / 2 ° GröH, GL, S ™ pli o “chamber P” ““. - / f- ° rSS “r. in e | ЙL °; - oz х x-П з - - SrcS: .- (. ь.
