Description

[0001] Apparatus for testing performance of a turbocharger [0002]

The present invention relates to a turbocharger performance evaluating apparatus which can perform a performance test on various turbochargers under the same conditions as when a turbocharger is mounted on an actual engine, And to perform various performance tests and durability tests of the turbocharger with one testing apparatus.

Generally, a turbocharger is used to increase the output of an engine in various internal combustion engines, and is usually applied to a diesel engine. However, the application range of a gasoline engine is increasing.

Therefore, it is important to accurately measure the performance of the turbocharger. Various types of measuring devices have been developed and used to measure the performance of the turbocharger.

As shown in FIG. 1, there is an apparatus for testing a turbocharger by supplying a high-temperature gas to a turbine of a turbo charger 45 using a combustion device (burner). However, since the exhaust gas is generated by using the combustion device, it is possible to produce the same temperature and flow rate as the exhaust gas generated from the actual engine, but it is not possible to make exhaust gas having pulsation like the actual exhaust gas.

That is, in the conventional turbocharger test apparatus, the performance curve of the compressor and the turbine is obtained by performing the test for the steady flow, but since it is not the form of the pulsating flow, there is a considerable error from the test result when the engine is mounted on the actual engine .

Therefore, it is preferable to test the turbocharger using a four-stroke multi-cylinder engine like the actual engine. However, in order to test various types of turbochargers, many types of engines are required, the configuration of the entire test apparatus is complicated, A dynamometer and the like are required for driving and controlling the load of the test apparatus.

2 is a schematic view showing a turbocharger performance evaluation apparatus according to an embodiment of the present invention;
3 is a schematic view showing a turbocharger performance evaluation apparatus according to another embodiment of the present invention.

Hereinafter, the turbocharger performance evaluating apparatus of the present invention will be described in detail with reference to the accompanying drawings.

[Example 1]

2 is a schematic view showing a turbocharger performance evaluation apparatus according to an embodiment of the present invention.

The turbocharger performance evaluation apparatus 1000 of the present invention is connected to a turbine 310 of a turbocharger 300 including a turbine 310 and a compressor 320 connected to a connection shaft 330 A two-stroke engine 100 for supplying exhaust gas to the turbine 310; And a controller (200) for controlling the number of revolutions (rpm) of the two-stroke engine (100); . ≪ / RTI >

First, the turbocharger 300 can be rotated together with the turbine 310 and the compressor 320 by the connection shaft 330. The exhaust gas inlet pipe 410 through which the exhaust gas flows and the exhaust gas outlet pipe 420 through which the exhaust gas is exhausted may be connected to the turbine 310. The compressor 320 may be connected to an intake air inflow pipe 510 and an intake air discharge pipe 520 through which intake air is discharged.

The exhaust port of the two-stroke engine 100 is connected to the exhaust gas inlet pipe 410 so that the two-stroke engine 100 can supply the exhaust gas to the turbine 310 of the turbocharger 300 described above. Here, the two-stroke engine 100 is an engine in which an explosion process is performed for each revolution of the crankshaft, and one cycle is completed in a descent stroke and a lift stroke (two strokes). When the piston is raised When the piston is lowered (descending stroke), explosion and exhaustion occur. When the piston is lowered, when the scavenging port is opened, the combustion gas remaining in the cylinder is discharged through the exhaust port, . At this time, in the two-stroke engine 100, there are no valves, an intake port through which the outside air is introduced, an exhaust port through which the combusted gas is exhausted, and a scavenge port for scavenging are formed by the operation of the piston (depending on the position of the piston) Thereby opening and closing.

The controller 200 may be connected to the two-stroke engine 100 to control the rotation speed (rpm) of the two-stroke engine 100. That is, the controller 200 measures the number of revolutions (rpm) through the revolving speed sensor 110 or the like provided in the two-stroke engine 100 and measures the amount of fuel supplied to the engine or the like in accordance with the measured revolutions of the two- So that the number of revolutions of the two-stroke engine can be controlled. That is, the controller 200 controls the two-stroke engine 100 so that the two-stroke engine 100 can be rotated at a desired speed, and accordingly, the frequency of the pulsation included in the exhaust gas exhausted from the two- And the flow rate of the exhaust gas can be adjusted. At this time, the rotation speed sensor 110 may be an encoder, and various measurement means capable of measuring the rotation speed of the two-stroke engine 100 may be used.

Thus, in the turbocharger performance evaluating apparatus of the present invention, the exhaust gas supplied to the turbine of the turbocharger can be pulsated by using the two-stroke engine, and the performance test can be performed under the same condition as when the turbocharger is mounted on the actual engine .

Since the two-stroke engine is used, the structure is simple compared to the four-stroke engine, and the entire apparatus for evaluating the performance of the turbocharger can be easily constructed, thereby saving a great deal of money.

In addition, using a two-stroke engine, one can test various types of turbochargers. That is, when the actual turbocharger is a four-stroke multi-cylinder engine, in the turbocharger performance evaluation apparatus of the present invention, the number of revolutions of the two-stroke engine is controlled to control the engine having various cylinders such as four cylinders, six cylinders, The exhaust gas can be made to have a pulsation having the same frequency as the pulsation of the exhaust gas generated in the exhaust gas.

In addition, since the two-stroke engine is used, the test can be performed at half the speed as compared to using the four-stroke engine. Therefore, the test can be easily performed at high speed and the durability of the turbocharger can be tested even under the extreme conditions that may occur in the vehicle , There is an advantage that the cost of the device can be reduced.

In this case, the two-stroke engine 100 may be a two-stroke single-cylinder engine having one combustion chamber, and may be a two-stroke single-cylinder engine connected in parallel to control the flow rate of the exhaust gas, It can also be used.

A rotation speed sensor 110 installed in the two-stroke engine 100 for measuring the rotation speed; A fuel tank 120 provided with a fuel pump and supplying the stored fuel to the two-stroke engine 100 side; A mechanical fuel injector (140) connected to the fuel tank (120) to receive fuel and installed in the two-stroke engine (100) and injecting fuel; The fuel injector 140 is installed in the fuel supply line 130 connecting the fuel tank 120 and the mechanical fuel injector 140 so that the fuel supplied from the fuel tank 120 is supplied to the mechanical fuel injector 140, An electronic relief valve (150) for bypassing the valve (120); And the rotation speed sensor 110 and the electromagnetic relief valve 150 may be connected to the controller 200 to control the operation of the engine.

That is, the fuel tank 120 receives the fuel, and the fuel tank 120 is connected to the mechanical fuel injector 140 installed in the two-stroke engine 100 by the fuel supply line 130, The fuel fed from the fuel pump provided in the fuel supply line 130 is supplied to the mechanical fuel injector 140 along the fuel supply line 130 and the electromagnetic relief valve 150 is installed in the fuel supply line 130, May be connected to the fuel tank 120 via the bypass line 160 and may flow back into the fuel tank 120 along the bypass line 160 during operation of the electronic relief valve 150. At this time, the electronic relief valve 150 may be connected to the controller 200 so that its operation can be controlled.

Thus, the rotation speed (rpm) of the two-stroke engine 100 is measured using the rotation speed sensor 110 provided in the two-stroke engine 100 and the electronic relief valve 100 is controlled according to the rotation speed of the two- The engine 150 can be controlled to open and close so that the mechanical fuel injector 140 does not inject or inject fuel into the two-stroke engine 100. At this time, since the mechanical fuel injector 140 injects the fuel only when the supplied fuel has enough pressure to push out the spring built in the injector, the two-stroke engine 100 reaches the desired number of revolutions The fuel is supplied to the mechanical fuel injector 140 so that the fuel is injected into the two-stroke engine 100 to increase the number of revolutions, and the two-stroke engine 100 When the desired number of revolutions is reached, the electronic relief valve 150 is operated to return the fuel to the fuel tank 120 through the bypass line 160, and the fuel is injected into the mechanical fuel injector 140 installed in the two- So that the fuel is not injected into the two-stroke engine 100, so that the rotational speed of the two-stroke engine 100 can be maintained without any further increase.

Here, the two-stroke engine 100 may be a mechanical two-stroke engine. However, the mechanical two-stroke engine is configured to operate only at a specific speed, and the mechanical two-stroke engine for a typical small-sized generator is designed to be driven at 3600 rpm. At this time, in the case of the mechanical two-stroke engine, the mechanical fuel injector 140 may include an injector injecting fuel into the engine and a mechanical fuel pump boosting the pressure of the fuel supplied from the fuel tank 120. That is, the injector injects the fuel only when the supplied fuel has a pressure enough to push out the spring incorporated in the injector, and the mechanical fuel pump has a governor that controls the rotation speed of the engine Speed), the amount of fuel supplied to the injector decreases as the number of revolutions of the engine increases, and when the predetermined speed is reached, the fuel supply is interrupted to stop the injection of fuel from the injector. Therefore, by eliminating or disabling the governor of the mechanical fuel pump and installing the electronic relief valve 150 on the fuel supply line 130, the electronic relief valve 150 is controlled according to the number of revolutions of the engine through the controller 200 The number of revolutions of the two-stroke engine can be obtained.

[Example 2]

3 is a schematic view showing a turbocharger performance evaluation apparatus according to another embodiment of the present invention.

As shown in the figure, the turbocharger performance evaluating apparatus 1000 of the present invention may further include a driving motor 170 connected to the two-stroke engine 100 to adjust the rotational speed.

That is, the drive motor 170 is coupled to the crankshaft of the two-stroke engine 100 so that the two-stroke engine 100 and the drive motor 170 are rotated together and the drive motor 170 is connected to the controller 200 And the rotation speed of the two-stroke engine 100 can be controlled faster or slower by controlling the drive motor 170. Thus, the frequency of the pulsation contained in the exhaust gas can be adjusted. At this time, the number of revolutions of the two-stroke engine 100 can be controlled using only the drive motor 170, and the opening and closing of the electromagnetic relief valve 150 can be performed together with the drive motor 170 and the number of rotations of the two- And the number of revolutions of the two-stroke engine can be controlled.

That is, the turbocharger 300 is connected to the exhaust gas inlet pipe 410 and the exhaust gas outlet pipe 420 to the turbine 310 so that the exhaust gas passes through the turbine 310, And may be configured to suck air by using the compressor 320 to discharge the compressed intake air. At this time, in order to measure the performance of the turbocharger 300, the flow rate on the inflow side of the exhaust gas is measured by the exhaust gas flow meter 610 installed in the exhaust gas inflow pipe 410 connected to the turbine 310, It is possible to measure the compressed intake air flow rate on the intake air discharge side by the intake air flow meter 710 provided in the intake air discharge pipe 520. The turbine inlet side temperature sensor 620 and the turbine inlet side pressure sensor 630 are installed in the exhaust gas inlet pipe 410 to measure the temperature and pressure of the exhaust gas flowing into the turbine 310, The discharge pipe 420 is provided with a turbine discharge side temperature sensor 640 and a turbine discharge side pressure sensor 650 to measure the temperature and pressure of the exhaust gas discharged from the turbine 310.
