Definitions
- the invention relates to a cylinder head for a water-cooled multi-cylinder internal combustion engine according to the features of the preamble of claim 1.
- the cooling circuit for a multi-cylinder internal combustion engine is shown and described in DE 100 21 525 A, in which approximately 2/3 of the coolant flow circulated for engine cooling is passed through the cylinder head housing in order to distribute the coolant flow as required.
- the coolant flows through the cylinder head housing in relation to the longitudinal axis of the cylinder bank.
- the object of the invention is to provide further measures in order to effectively and uniformly cool the areas of the cylinder head which are exposed to high temperatures.
- a cooling adapted to the temperature load in the cylinder head is achieved within the cylinder head of a multi-cylinder internal combustion engine, in which a main coolant flow is conducted between the two outlet valves of the four-valve engine in the direction of the spark plug dome, while the edge zones of the cylinder head cold rooms are supplied by secondary cooling flows.
- the coolant is advantageously conducted into the area of the spark plug dome exposed to high temperatures through the guide ribs provided at the opening for the spark plug. Because the cross sections of the two guide ribs are designed differently, a transverse flow is generated behind the guide ribs, which counteracts the formation of so-called dead water areas and contributes to an adequate supply of coolant also in the area of the inlet valves.
- the diameter of the outflow openings be of different sizes.
- an additional cooling channel is provided on the inflow side in the cylinder head, which leads coolant directly to the hot spot.
- 1 shows a geometric illustration of a water jacket in the cylinder head housing of an internal combustion engine
- 2 shows a section along the line II-II in FIG. 1
- Fig. 3 is a side view of the water jacket in the direction of arrow A in Fig. 1 and
- FIG. 4 shows a view of the water jacket from direction B in FIG. 3.
- FIG. 1 The figures show the geometry of a water jacket, hereinafter referred to as cylinder head cooling chamber 2, of a cylinder for a multi-cylinder internal combustion engine, as described, for example, in DE 100 21 525 AI.
- the cylinder head cooling chamber 2 of each cylinder is over two in
- Inlet openings 4 and 6 provided with cylinder head housing are supplied with cooling water.
- two outflow openings 8 and 10 are provided, through which the coolant heated by the cylinder head flows to the suction side of the water pump, not shown, of the internal combustion engine.
- two recesses 12 and 14 for the two intake valves of the internal combustion engine can be seen; an opening 16 provided centrally in the cylinder head cooling chamber 2 forms the receptacle or dome for the spark plug of the cylinder in question.
- rib-shaped recesses 18 and 20 which are formed in the cylinder head housing as a positive as two guide ribs 18 ' and 20 ' .
- the cross sections of the two guide ribs 18 ' and 20 ' are of different strengths; the function of this configuration will be explained in more detail later.
- a recess 22 for the two inlet valves of the cylinder head follows behind the two recesses 18, 20 and the central opening 16.
- the inflow side of the cylinder head cooling chamber 2 is designed such that a main cooling flow Q2 and Q 3 is guided between the two exhaust valves (recess 12, 14) in the direction of the spark plug dome (central opening 16) via the inflow openings 4 and 6, while in the left and right respectively
- a secondary cooling flow Qi and Q 4 is formed at the edge region of the cylinder head cooling space 2 and is guided along the two outflow openings 4 and 6 on the outside of the two recesses 24 and 26 in the direction of the ribs 18 ' and 20 ' .
- the cooling flows Q 2 and Q 3 are directed on the basis of the spark plug dome in the direction of the guide ribs 18 ' and 20 ' , where they meet the cooling flows Q1 and Q4.
- the cooling flow Q5 generated by the cooling channel 28 leads coolant directly to a hot spot in the cylinder head housing, which is formed in the wall area of the combustion chamber at the level of the spark plug dome, which encloses the opening or the thread for receiving the spark plug.
