Definitions
- Cylinder of an internal combustion engine for a vehicle and corresponding manufacturing method means for producing the cylinder, spark plug, internal combustion engine and vehicle
- the present invention relates to a cylinder of an internal combustion engine for a vehicle and a manufacturing method, which is designed for the production of the cylinder, and means which are used for the production of the cylinder. Moreover, the present invention relates to a spark plug, an internal combustion engine and a vehicle, each of which is receivable in the cylinder according to the invention, or have a cylinder according to the invention.
- DE 10 2006 042 457 B4, DE 103 49 077 A1 and DE 10 2007 024 878 A1 disclose arranging a spark plug in a specific orientation to the intake valves of the cylinder in a cylinder.
- DE 101 38 976 A1 describes a device for detecting a pre-ignition combustion in an internal combustion engine.
- a pre-ignition in which an uncontrolled ignition process of the cylinder charge occurs more or less clearly before the planned ignition timing. Due to the early implementation of the air-fuel mixture and the additional compression it comes to very high cylinder pressures. Due to the increased thermal state after the start of combustion, detonation with subsequent knocking combustion often occurs. The coincidence of these conditions can lead to a cylinder pressure of greater than 250 bar in an Otto engine and thus to the immediate failure of the engine.
- the present invention has the object to provide a cylinder in which a pre-ignition occurs less frequently than in a comparable prior art cylinder.
- this object is achieved by a cylinder according to claim 1, by a manufacturing method for producing a cylinder according to claim 7, by means for producing a cylinder according to claim 12, by a spark plug according to claim 13, by an internal combustion engine according to claim 15 and by a vehicle Claim 16 solved.
- a cylinder of an internal combustion engine for a vehicle comprises one or more inlet channels and a spark plug.
- the spark plug in turn has a ground electrode.
- the spark plug is mounted in the cylinder such that the spark plug has an orientation within a predetermined orientation range (ie, an orientation of the cylinder within a predetermined range of tolerance (eg, angular range) relative to the at least one intake port of the cylinder) to bypass the mass electrode by a combustion engine Air flow, which is generated by or through the inlet channels to cool. That is to say the spark plug is mounted or arranged in the cylinder in such a way that the air flow generated by the at least one inlet duct optimally cools the mass electrode, taking into account tolerances during assembly of the spark plug.
- the basic idea of the present invention is to use the air flow, which is generated by the at least one inlet channel during operation of the internal combustion engine, for cooling the mass electrode of the spark plug.
- the air flow which is generated by the at least one inlet channel during operation of the internal combustion engine.
- numerous orientations have been investigated as to how hot the ground electrode becomes during operation of the internal combustion engine.
- To determine the optimal orientation of the spark plug temperature measurements were performed on the spark plug on an optically accessible engine, using a special measurement technique (infrared thermometry) was used.
- the present inventors have recognized that for the cooling of the mass electrode by the air flow of the at least one inlet channel it is advantageous to fasten or mount the spark plug in the cylinder such that an open end of the mass electrode substantially (ie with a predetermined tolerance) is arranged in the direction of the at least one inlet channel.
- the spark plug is mounted (eg, rotated) in the cylinder such that the open end (ie, unattached end) of the ground electrode is directed to the at least one inlet port such that the airflow entering via the at least one inlet port is directed toward the open port End of the ground electrode impinges and this cools.
- the inventors have investigated two different variants.
- the open end of the ground electrode was arranged in the direction of the intake valves and in the second variant in the direction of the foreign valves.
- the hottest point of the ground electrode which is usually at the open end of the ground electrode, a temperature higher by 40 to 60 ° C than the temperature of the hottest point of the ground electrode in the first variant. Therefore, the targeted mounting position of the spark plug with an orientation of the mass electrode in the direction of the inlet valve (inlet channels) advantageously reduces the temperature at the ground electrode considerably, whereby the maximum temperature of the spark plug and thereby the frequency of pre-ignition can be significantly reduced.
- the open end of the mass electrode is directed precisely to this one inlet channel.
- the open end of the ground electrode is directed taking into account the tolerance between the two inlet channels.
- the tolerance is advantageously at most ⁇ 90 °, better ⁇ 45 ° and best ⁇ 5 °.
- the spark plug is rotated in the assembly according to the invention around its longitudinal central axis, that they with respect to the optimal orientation, in which the open end of the ground electrode exactly on the inlet channel (with exactly one inlet channel) or exactly between the two inlet channels (with exactly two inlet channels), maximum 90 ° (45 ° or 5 °) clockwise or maximum of 90 ° (45 ° or 5 °) opposite to Turned clockwise.
- precisely between the two inlet channels is meant in particular a point which is located between the two inlet channels on a straight line which connects the center of the outlet of the one inlet channel into the combustion chamber with the center of the outlet of the other inlet channel into the combustion chamber.
- this point has the same distance from the center of the exit of the one inlet channel from the center of the outlet of the other inlet channel.
- the cylinder comprises means for arranging the spark plug in the cylinder according to the invention, so that the open end of the mass electrode is arranged in the direction of the at least one inlet channel taking into account the tolerance.
- these means may, for example, include certain markings to place the spark plug in the desired manner in the cylinder.
- a certain stop is present, so that the spark plug, when mounted in consideration of this stop, according to the invention is aligned with the at least one inlet channel.
- the cylinder in particular the cylinder head
- the spark plug comprises an external thread, which is adapted to the internal thread, that the spark plug after assembly, wherein the spark plug is screwed with a predetermined torque in the internal thread, aligned with the predetermined tolerance in the predetermined direction with respect to the at least one inlet channel becomes.
- the internal thread of the cylinder and the external thread of the spark plug are adapted accordingly, i.
- the spark plug for mounting in a predetermined orientation with respect to the cylinder must be arranged so that the internal thread can be brought into engagement with the external thread, the end position (ie the post-assembly position) of the spark plug and thus the orientation of the open end of the ground electrode to the at least one inlet channel, taking into account the tolerance.
- the present invention also provides a manufacturing method for manufacturing a cylinder of an internal combustion engine for a vehicle.
- a spark plug is mounted in the cylinder so as to ensure that the spark plug is oriented in a predetermined orientation range with respect to one or more intake passages of the cylinder so that a spark plug mass electrode is generated by one of the at least one intake passage when the engine is running Air flow is optimally cooled.
- the manufacturing process ensures that the spark plug (especially the open end of the ground electrode) has the desired orientation with respect to the at least one intake port after assembly.
- a production method which achieves this desired orientation only by chance (ie not guaranteed for each cylinder) does not ensure the desired alignment of the spark plug with the at least one inlet channel.
- the spark plug is in particular mounted by a rotation about the central longitudinal axis (or longitudinal center axis) of the spark plug in the cylinder. That is, the spark plug is screwed by the rotation about the central longitudinal axis in the cylinder (in particular the cylinder head). In this case, the spark plug is rotated in an end position such that the open end of the mass electrode, taking into account the tolerance in the direction of the at least one inlet channel.
- the spark plug comprises an external thread and the cylinder an internal thread.
- the internal thread and the external thread are adapted to each other such that the open end of the ground electrode due to the adaptation of the internal thread to the external thread almost inevitably shows the predetermined tolerance towards the at least one inlet channel when the spark plug has been screwed into the internal thread.
- means are also provided for producing a cylinder of an internal combustion engine for a vehicle.
- these means are such that with the aid of these means, the spark plug can be mounted in the cylinder, that ensures that the spark plug with respect to one or more inlet channels of the cylinder has an orientation in a predetermined orientation region, thus with the internal combustion engine, a ground electrode the spark plug is cooled as optimally as possible by an air flow generated by the at least one inlet channel.
