Definitions
- the invention relates to a liquid-cooled reciprocating internal combustion engine according to the preamble of the claim 1 off.
- a bypass line connects in the cooling circuit the return line with the inlet line. You bridged the cooler and flows into the upstream of the water pump Supply line.
- a three-way valve which regulates the flow of coolant and thermostatically or from a control unit is controlled.
- the control unit is via signal lines with numerous different sensors connected, which are the operating parameters and environmental parameters the reciprocating internal combustion engine and the cooling or Record the heating circuit.
- a cooling circuit is known in which the inlet pipe branches into two inlet pipes, the one inlet pipe in the area of the cylinder head and the other in the area of the cylinder block in the reciprocating piston internal combustion engine empties.
- the coolant flow regulated by a valve which is in the inlet line is arranged to the cylinder block.
- the valve position is regulated by a control unit, which among other things Evaluates temperature measurements on the reciprocating piston internal combustion engine.
- a first temperature sensor measures the temperature of the flowing coolant, which provides information about the Total cooling of the reciprocating piston internal combustion engine there.
- On second temperature sensor measures the temperature of the machine oil, whereby the cooling in the area of the cylinder block is determined becomes.
- the valve is set according to the measurement data, see above that exactly certain subsets through the separate inlet lines flow to the cylinder head or cylinder block.
- the coolant flows through the separate inflow Targeted in the two areas, but will be later again blended because the cooling channels have a volume flow between the areas and thus an exchange of coolant allow.
- Temperature measurements of the mixed coolant do not represent the actual operating conditions in the individual areas of the reciprocating piston internal combustion engine and the control of the cooling circuit is not precise their special temperature conditions matched.
- the coolant spaces of the cylinder head and the cylinder block separated and via separate outlet lines on a common return line connected.
- the coolant flows flow via separate inlet lines, each with a Control valve is provided in the two areas of the reciprocating piston internal combustion engine and are also during the cooling process not mixed. They also leave the reciprocating piston internal combustion engine also via separate outlet lines.
- Temperature measurements in the cylinder head exhaust pipe or the cylinder block in this case represent the the respective cooling process is unadulterated.
- the amount of coolant flowing through it adjust efficiently to the area to be cooled.
- the area of the cylinder head can be marked by a increased coolant flow in an optimal temperature range be held without the cylinder block, which usually does not need to be cooled as much, is also flowed around by the coolant.
- the invention advantageously provides that the two Control valves in the inlet lines individually or together are controllable, so that in addition to the need-based throttling of the coolant flow to one of the two, separate Areas of the reciprocating piston internal combustion engine in many Operating points also the total volume flow of the coolant is reduced, which is the case with known cooling circuits not possible.
- the two control valves arranged in the outlet lines instead of in the inlet lines his.
- the coolant control according to the invention causes the reciprocating internal combustion engine to quickly optimal operating temperature reached and over wide operating ranges maintains. This will reduce fuel consumption and reduced pollutant emissions.
- the only drawing shows a schematic representation a cooling circuit of a reciprocating piston internal combustion engine.
- a reciprocating piston internal combustion engine 10 is on a cooling circuit 16 connected.
- a water pump 18 delivers coolant via a pressure line 32 to the reciprocating piston internal combustion engine 10 and from there through a return flow line 26 a cooler 20, which cooperates with a fan 24.
- the coolant flows from the cooler 20 through a suction line 30 back to the water pump 18.
- the coolant flow is indicated by arrows.
- the pressure line 32 branches into a first inlet line 34 leading to a cylinder head 12 of the internal combustion engine 10 leads, and into a second inlet line 36 leading to a Cylinder block 14 of the internal combustion engine 10 leads.
- the cylinder head 12 and the cylinder block 14 have no closer shown, separate coolant spaces. The separation is indicated by a dashed line 46.
- the cylinder head 12 is via a first outlet line 38 and the Cylinder block 14 via a second outlet line 40 with the common return line 26 connected.
- By the separate Coolant flow in the cylinder head 12 and in Cylinder block 14 is the temperature of the coolant in the outlet lines 38, 40 representative of the heat and the cooling processes in the cylinder head 12 or in the cylinder block 14.
- Sensors not shown in the outlet lines 38, 40 together with one can also Control unit not shown and the control valves 42, 44 in the inlet lines 34, 36 the temperature behavior determine precisely in the cylinder head 12 and in the cylinder block 14.
- a first control valve 42 is sufficient, which in the first or second inlet line 34, 36 is arranged.
- this control valve 42 By controlling this control valve 42, the volume flow through the corresponding inlet line 34 or 36 throttled while the rest, by the water pump 18 delivered volume flow through the other inlet line 34 or 36 flows.
- a first control valve 42 in the first inlet line 34 and a second Control valve 44 in the second inlet line 36 can total volume flow to both the inlet pipes 34 and 36 are split as well as throttled so that the amount of coolant flowing through the reciprocating internal combustion engine 10 in operating areas with low heat generation can be reduced.
- the first and second control valve 42, 44 on the outflow side in the outlet lines 38, 40 are arranged.
- the cooling circuit 16 can have a conventional structure have, in which between the return line 26 and the Suction line 30 parallel to the cooler 20, a bypass line 28 and a heat exchanger 22 are connected.
- a third Control valve 48 which as a thermostatic valve or as one of the control unit controllable valve is designed, regulates the flow through the heat exchanger 22, the bypass line 28 and the cooler 20.
- the cooling circuit 16 other heat exchangers for work and Include auxiliary units.
