Definitions
- the invention relates to a water-cooled, multi-cylinder internal combustion engine according to the features of the preamble of claim 1.
- a water-cooled internal combustion engine in which between the two cylinder banks a two cooling circuits controlling thermostat is arranged in a surrounding him thermostat housing.
- the thermostat housing consists of an integrally connected to the crankcase upper part lower part and a thermostat cover, are formed on the corresponding inlet and outlet nozzles.
- corresponding wall sections are provided in the lower part, are formed by the corresponding controllable by the thermostat chambers.
- a cooling water device for an internal combustion engine which has a thermostat device with two thermostatic valves. After a first heating of the cooling water passes through the opened first thermostatic valve, a subset of the cooling water in a bypass line, wherein the conveyed through the bypass line cooling water quantity is controlled in dependence on the cooling water temperature by means of the second thermostatic valve.
- the object of the invention is to develop for a water-cooled multi-cylinder internal combustion engine, a thermostat receiving housing, which is characterized by a simple, aerodynamic and weight-optimized design, which also takes up little space to complete.
- the proposed insert according to the invention water chambers are formed, the openings are monitored by the thermostatic valve.
- the insert is easy to prepare and consuming in the lower part of the thermostat housing usually necessary wall sections can be omitted.
- crankcase upper part 2 of a V8 - engine has for each cylinder bank row a cylinder 1 to 4 and 5 to 8 enclosing the cooling jacket.
- a water pump 6 is arranged on an end face 4 of the internal combustion engine.
- the water pump 6 consists of a cover part 8, in which the Wasserpumpenrad 10 is mounted.
- the housing 12 of the water pump 6 is arranged, which is integrally formed out of the crankcase upper part 2.
- an intake manifold 14 is provided in the housing 12, which merges into a first coolant - return chamber 16 forming lower part 18 of a thermostat housing, wherein the lower part 18 is integrally formed out of the crankcase upper part 2.
- a thermostat insert 20 is used, which is bolted by means not shown fastening means in the lower part 18 of the thermostat housing.
- the trough-shaped and manufactured, for example, die-cast aluminum insert 20 has at its bottom a cylindrical opening 22 which, as described in more detail below, by a first valve plate 24 of a thermostatic valve 26 is monitored.
- the thermostat insert 20 has in the lateral wall region on another, provided with a nozzle 28 opening 30. The nozzle 28 is inserted sealingly into the intake 14 of the water pump housing 12 via a 0 - ring 32.
- the thermostat housing is closed by an upper part 34 which is sealed with its flange surface 36 relative to the flange 38 of the lower part 18.
- thermostatic upper part 34 On the underside of the thermostat upper part 34 is a line corresponding to the dashed line (see Fig. 4 ) extending inner flange surface 40 is provided, which seals in the assembled state against the tub rim 42 of the insert 20 and whereby in the Einlegteil 20, a second coolant - return chamber 44 is formed.
- the thermostatic upper part 34 has a connecting piece 46 leading to a cooler, not shown, which communicates with the first coolant return chamber 16.
- a second connecting piece 48 for the back flowing from the radiator. Cooling water is connected via an opening formed in the return port 48 opening 50 with the second coolant return chamber 44 in connection.
- the opening 50 is monitored via a second valve plate 52 of the thermostatic valve 26.
- a holding plate 54 For attachment of the thermostatic valve, a holding plate 54 is provided, which is fastened to two holding webs 56 and 58 which are cast on the flange side of the thermostat upper part 34.
