Definitions
- the invention relates to an internal combustion engine, in particular a gas internal combustion engine.
- a gas internal combustion engine is known from JP 2001-214811 A, in which gas is fed into an inlet duct via a gas feed pipe, the gas feed pipe having a series of radial openings through which the gas is blown in the direction of the inlet flow.
- the mouths of the gas supply pipe are arranged as close as possible to the mouth into the combustion chamber in order to keep the residual gas not participating in the combustion as small as possible in the inlet duct and to reduce flushing losses. Because the gas is blown into the inlet duct close to the mouth, mixing with the fresh air is not sufficient.
- Combustion processes with a prechamber are used, among other things, in lean (with a high air ratio) operated gas engines, from a certain cylinder stroke volume.
- lean with a high air ratio
- the advantage of initiating combustion in the prechamber instead of in the main combustion chamber is that even in high air conditions, a low ignition energy is sufficient to ensure efficient (with good efficiency) and yet low-pollution combustion of the entire cylinder charge (in the prechamber and main combustion chamber).
- the prechamber is fluidly connected to the main combustion chamber via one or more holes.
- the fuel gas / air mixture flows into the main combustion chamber via one or more inlet valves and is subsequently pushed into the prechamber during the compression process, so that a combustible mixture is available in it.
- electrical spark ignition systems and also ignition beam processes are used to ignite the fuel gas / air mixture.
- pure fuel gas or a fuel gas / air mixture is often introduced into the prechamber in order to have a significantly richer and therefore more readily combustible mixture available at the point of combustion initiation compared to the main combustion chamber.
- combustion in the prechamber can also be initiated by homogeneous self-ignition, as described in AT 6.290 Ul.
- Flame torches flow from the antechamber into the main combustion chamber and also ignite the fuel gas / air mixture located there.
- the auto-ignition temperature must be exceeded so that the injected or injected ignition jet can auto-ignite.
- the temperature increase of the residual gas / fuel gas / air mixture in the prechamber results primarily from the compression process. Wall heat losses, however, in turn reduce the temperature of the gas mixture and thus make auto-ignition difficult. Especially when starting an ignition jet engine, the wall heat losses are particularly high, which makes starting the engine considerably more difficult.
- EP 0 097 320 A2 discloses a prechamber or swirl chamber for internal combustion engines which has an inner molded body which forms the interior and an outer molded body which is made of ceramic material and forms thermal insulation and is externally connected to the inner molded body by shrinking or gluing.
- Antechambers with thermal insulation on the outside of the antechamber body are also known from the publication DE 864 173 B. Despite the insulation, the antechambers are subject to high mechanical and thermal loads.
- the object of the invention is to improve the mixture homogeneity and reduce the purge losses in an internal combustion engine of the type mentioned. Another object is to reduce the heat losses in an internal combustion engine with a prechamber connected to a main combustion chamber for initiating the combustion.
- At least one flow path for supplying the gaseous fuel opens into at least one inlet duct, the gas supply to the gas flow path being controllable by a gas valve.
- the gas supply pipe has at least one longitudinal slot and / or at least one elongated hole, the longitudinal slot being able to run out towards an end opening of the gas supply pipe.
- a longitudinal slot or an elongated hole is arranged on the side of the gas supply pipe facing away from the fresh air flow, it being possible for a further longitudinal slot or a further elongated hole to be arranged on the side facing the fresh air flow.
- the contact surface with the fresh air is significantly increased and the mixing is improved.
- the fresh air can optimally flush out the gas supply pipe through the front opening and the longitudinal slot or the elongated hole, so that after the gas valve is switched off, hardly any residual gas remains in the gas supply pipe and almost all of the supplied gas participates in the combustion. This means that flushing losses can be significantly reduced.
- the gas supply pipe is chamfered in the region of the front opening, the opening preferably being arranged on the side facing away from the fresh air flow in the inlet duct. It is particularly advantageous for thorough mixing of the gas with fresh air and for a good flushing out of the gas supply pipe if the gas supply pipe is at least partially directed against the fresh air flow in the inlet duct.
- At least two gas flow paths preferably a first and a second gas flow path, open into the inlet channel in different areas.
- Two gas flow paths for supplying the fuel gases are particularly advantageous for internal combustion engines with two inlet valves, which are arranged behind one another in terms of flow in the mouth region of a single inlet channel.
- the second gas flow path - viewed in the direction of the air flow in the inlet channel - opens into the inlet channel downstream of the first gas flow path
- the first and second gas flow paths preferably opening into different cross-sectional areas of the inlet channel, advantageously the first inlet flow path within the inlet channel is longer than the second inlet flow path. Because the gas supply pipes are of different lengths, the gas can flow in different cross-sectional areas of the inlet channel, as a result of which the gas flowing in via each inlet valve can be metered separately and mixed particularly well with fresh air.
- the gas flow paths can be arranged either in the cylinder head or in a combined intake-exhaust manifold part.
- the invention provides that the thermal insulation is formed by an insulation insert inserted into the prechamber, the insulation insert preferably being designed as a sleeve.
- the resulting gap between the sleeve and the actual prechamber body makes the heat flow more difficult.
- the sleeve advantageously consists of a heat-resistant material or several materials, for example at least partially of ceramic.
- the sleeve can be easily inserted into existing pre-chamber designs by simple adaptations, making it possible to retrofit engines in series at low cost. Particularly small measures are required if the sleeve is rotationally symmetrical, preferably cylindrical, and the prechamber is cylindrical at least in sections is.
- the sleeve is preferably inserted into a recess produced, for example, by a milling or turning process, in accordance with the shape of the sleeve.
- the prechamber body is constructed in several parts and consists at least of a first part receiving the sleeve and a second part closing the prechamber in the axial direction.
- a particularly advantageous embodiment variant of the invention provides that the inner lateral surface of the sleeve adjoins the adjoining prechamber wall.
- the residual gas / fuel gas / air mixture in the antechamber reaches sufficiently high temperatures towards the end of compression (shortly before the piston reaches top dead center).
- FIG. 1 shows an internal combustion engine according to the invention in a longitudinal section through an inlet duct in a first embodiment
- FIG. 2 shows an internal combustion engine according to the invention in a longitudinal section through an inlet duct in a second embodiment variant
- FIG. 3 shows an inlet-outlet manifold part from FIG. 1 in an oblique view
- Fig. 4 shows the gas supply pipe from Fig. 1 in detail
- Fig. 5 shows a prechamber according to the invention in longitudinal section.
- the gas internal combustion engine 1 shown in FIGS. 1 to 4 for the combustion of a gaseous fuel has an inlet channel 3 per cylinder 2, which divides into two subchannels 5, 6 before entry into the combustion chamber 4, the inlet cross section of which is divided by inlet valves 7, 8 is controlled.
- the gas is supplied via a first and a second gas flow path 9, 10, the gas flow paths 9, 10 being formed by first and second gas feed pipes 11, 12 opening into the inlet channel 3.
- the amount of gas supplied is controlled via an electrically actuated gas valve 13.
- the first and second gas flow paths 9, 10 may be arranged in a combined intake-exhaust manifold part 15 which is separate from the cylinder head 14, as shown in FIG. 1. Alternatively, it is also possible that the first and second gas flow paths 9, 10 are arranged in the cylinder head 14 and that the gas valve 13 is attached directly to the cylinder head 14 (FIG. 2).
- the first and second gas supply pipes 11, 12 are of different lengths and open into the cross section of the inlet channel 3. This ensures that both subchannels 5, 6 are equally adequately supplied with a fuel-air mixture.
- the first gas supply pipe 11 has a longitudinal slot 16 which faces away from the fresh air flow S and which extends over a large part of the first gas supply pipe 11.
- the gas supply pipe is provided with an opening 18 on its end face 17 projecting into the inlet duct.
- the longitudinal slot 16 runs towards the front into this front opening 18.
- the first gas supply pipe 11 is chamfered in the region of its end face 17, so that the opening 18 of the fresh air flow S is turned away.
- the gas supplied via the gas valve 13 flows through the first and second gas supply pipes 11, 12 into the inlet channel 3.
- the inflow through the first gas supply pipe 11 takes place via the entire longitudinal slot 16 and via the front opening 18. This creates a relatively large contact surface with the inflowing fresh air, which produces a particularly good mixing of the fuel with the fresh air. Since the gas flows through the first and second gas supply pipes 11, 12 into different cross-sectional areas of the inlet duct 3, the mixing is promoted and the two sub-ducts 5, 6 are supplied with a fuel-air mixture.
- the gas supply pipe 11 can also have a longitudinal slot or an elongated hole 16 'on the side facing the fresh air flow.
- the gas supply pipe 11 is flushed with fresh air by inserting a portion of the fresh air of the inlet duct 3 through the rear longitudinal slot or the elongated hole 16 'and through the front opening 18 of the first gas supply pipe 11 and through the longitudinal slot facing away from the fresh air flow 16 leaves again. It is advantageous if the gas supply pipe 11 is at least partially directed against the flow direction S of the fresh air in the inlet duct 3, as can be seen, for example, from FIG. 3.
- the first gas supply pipe 11 opens into the inlet channel in the region of an external curvature of the inlet channel 3.
- 5 shows a prechamber 101 in longitudinal section.
- the pre-chamber 101 is arranged in the cylinder head 102 of an internal combustion engine, not shown.
- the interior 103 of the prechamber 101 opens into a main combustion chamber 105 of the internal combustion engine via openings 104.
- the prechamber body 106 of the prechamber 101 is constructed in several parts and consists of at least a first part 107 and a second part 108 which closes off the first part 107 in the axial direction.
- the longitudinal axis of the prechamber 101 is designated 101a.
- the first part 107 spans the interior 103 and has a cylindrical section 109, in which a cylindrical recess 110 is formed, for example by milling or turning.
- a thermal insulating insert 112 formed by a cylindrical sleeve 111 is inserted into the recess 110 of the first part 107, which on the one hand reduces the heat losses and on the other hand reduces the thermal load on the prechamber body 106.
- the reduction in heat losses is realized on the one hand by the parting line 113 between the prechamber body 106 and the insulating insert 112, and on the other hand by the choice of a heat-resistant material with low thermal conductivity, for example ceramic.
- the inner lateral surface 114 of the sleeve 111 adjoins the prechamber wall 115 as seamlessly as possible, so that disturbances in the flow and combustion process within the prechamber 101 are avoided.
- An injection valve and / or an ignition device can open into the interior 103 of the pre-chamber 101 via the second part 108, as indicated by reference numerals 116 and 117.
- this measure for thermal insulation can ensure reliable auto-ignition and ensure stable, rapid combustion in the pre-chamber 101 and subsequently in the main combustion chamber 105.
- pilot jet engines it is possible to reduce the injection quantities of liquid fuel required, which can achieve advantages in NO x emissions.
- a better starting behavior of the internal combustion engine can also be achieved through the better thermal insulation of the pre-chamber 101, since the temperature levels necessary for good ignition behavior can be reached more quickly.
- ignition and combustion can also be found in prechamber concepts with homogeneous combustion in prechamber 101.
- prechamber internal combustion engines with electrical ignition the stability and the speed of the combustion in the prechamber 101 and thus also in the main combustion chamber 105 can be increased.
- references used in the subclaims indicate the further development of the subject matter of the skin claim through the features of the respective subclaim; they are not to be understood as a waiver of the achievement of independent, objective protection for the characteristics of the related subclaims.
