Definitions
- the invention relates to a cylinder head for a water-cooled Internal combustion engine according to the preamble of patent claim 1.
- EP 0353988 A1 shows in FIG. 3 a cylinder head that is water-cooled and one Has hot spot in the area of a wall of the cylinder head.
- the hot spot extends between a central spark plug and a combustion chamber.
- US 2,305,457 also treats a water-cooled cylinder head Cooling channels that are routed around exhaust valves. These cooling channels point adjacent to the outlet valves on walls, which is distributed by means of spray nozzles Cooling medium to be cooled.
- the object of the invention is a cooling channel of a cylinder head To design the internal combustion engine such that, above all, pronounced hot spots of the Cylinder head are supplied with flowing cooling water via the cooling channel.
- the main advantages achieved with the invention are that the Control measures in the cooling duct of a light metal alloy Cylinder head cause a targeted cooling water flow in the area of the hot spot i.e. on the wall of the cooling channel, which is, for example, between a central Spark plug and a combustion chamber extends.
- the tax arrangements are then particularly effective when provided adjacent to the hot spot in the cooling channel are in which the cooling water as a cross flow from the outlet side to the inlet side flows.
- the control arrangements are made for each combustion chamber by a guide rib and Locking ribs formed in the cooling channel. They cause a targeted flow of the cooling water to the hot spot and reduce the risk of a temperature-related Overuse. On the one hand, this enables the constructive Design of a cylinder head using standard materials - AlSi 10 or AlSi 7 and on the other hand, that the committee that is currently working on cylinder heads of internal combustion engines is particularly costly, is significantly reduced.
- a multi-cylinder internal combustion engine 1- Otto type - with water cooling includes in the area shown a cylinder head 2 and a cylinder housing 3, which a light metal alloy and composed in a parting plane 4 are.
- the cylinder head 2 is per cylinder with two intake valves and two exhaust valves - Not shown - provided that with their valve plates with valve seats 5.6 and 7.8 work together.
- the valve seats 5,6 have a larger diameter than that Valve seats 7,8, the valve seats 5,6 interacting with the inlet valves; the Valve seats 7,8 with the outlet valves.
- a fuel-air mixture - intake manifold injection - supplied by a spark plug 11 is ignited and then through the exhaust valves Exhaust side 12 enters an exhaust system, not shown.
- the one Threaded bore 13 of the cylinder head 2 inserted spark plug 11 runs in one Central longitudinal plane C - C of a cylinder 14 - or at a short distance from it -, i.e. she has a central location in the combustion chamber 10.
- a cooling channel 15 is provided, which of a first longitudinal channel 16 Cylinder housing 3 is supplied with said cooling water.
- the longitudinal channel 16 delimits with a cylinder wall 17 a cylinder liner 18 of the cylinder 14, and locally with formation of an annular space 19, which leads to the entry of cooling water an opening 20 is connected to the longitudinal channel 16.
- the cooling water flows from the outlet side 12 coming from the longitudinal channel 16 via the cooling channel 15 to the Intake side 9 out - a cross flow in the cylinder head 2 causing cooling channel 15 - and is discharged through a second longitudinal channel 21 of the cylinder head 2.
- the cooling duct 15 results from radiant heat during operation of the internal combustion engine 1 the combustion chamber 10 a hot spot 22 on a wall 23, the threaded hole 13th and limits the combustion chamber 10.
- this hot spot 22 ensure are in the cooling channel 15 of the cylinder head 2 on the exhaust side 12th
- Control arrangements 24 are arranged with which the cooling water flow in such a targeted manner the hot spot 22 is passed that the thermal load on the wall 23 of the Cylinder head 2 is reduced.
- Controls 24 are at 25, so adjacent hot spot 22 and are formed by a guide rib 26.
- This guide rib 26 has a deflection edge 27, one with dash-dotted lines shown, accelerated cooling water flow Ks generated.
- the guide rib 26 extends in the Transverse plane A - A between the exhaust valves.
- the Control arrangements 24 in the cooling channel 15 two - seen in the transverse direction A - A - with Distance from each other locking ribs 28, 29, which are symmetrical on both sides of the Guide rib 26 run.
