Abstract

A standard engine cold test method includes instructing, by a control device, a tester to perform an engine test. The tester drives a motor with a standard mode or a general mode according to a control of the control device to operate an engine which is a test object. The tester measures engine information depending on an operation of the engine using a sensor. A gathering device gathers the measured engine information. The gathered engine information is analyzed to determine abnormality of the engine.

Claims

1. A standard engine cold test system, comprising:

a control device configured to control an engine test operation;

a tester configured to operate an engine by driving a motor according to a control of the control device and measure engine information depending on an operation of the engine;

a gathering device configured to gather the engine information outputted from the tester; and

an analysis device configured to analyze the engine information gathered by the gathering device to determine abnormality of the engine.

2. The standard engine cold test system according to claim 1, wherein the control device includes:

a main controller configured to generate and transmit a measurement command; and

a driving controller configured to control a motor starting mode with a standard mode or a general mode according to the measurement command.

3. The standard engine cold test system according to claim 2, wherein the measurement command includes a measurement mode and a kind of measurement data.

4. The standard engine cold test system according to claim 3, wherein the measurement mode is classified into a standard measurement mode which is based on a measurement standard and a general measurement mode which is not based on the measurement standard.

5. The standard engine cold test system according to claim 4, wherein when the measurement mode of the measurement command is the standard measurement mode, the driving controller determines the motor starting mode as the standard mode and changes driving control setting information to standard control setting information for controlling a standardized motor driving according to a kind of engine.

6. The standard engine cold test system according to claim 4, wherein when the measurement mode of the measurement command is the general measurement mode, the driving controller determines the motor starting mode as the general mode and sets the driving control setting information as a default value.

7. The standard engine cold test system of claim 5, wherein the driving control setting information includes a motor slope, a motor speed, and a motor speed gain.

8. The standard engine cold test system according to claim 1, wherein the tester includes:

a motor configured to be connected with the engine and deliver power to the engine;

a motor driver configured to drive the motor according to the control of the driving controller; and

a sensor configured to measure engine information depending on the operation of the engine.

9. The standard engine cold test system according to claim 8, wherein the engine information includes at least one of starting torque and rotating torque.

10. The standard engine cold test system according to claim 1, wherein:

the analysis device checks whether the gathered engine information is out of a threshold range, and

when it is determined that the engine information is out of the threshold range, the analysis device determines that the engine is abnormal.

11. The standard engine cold test system according to claim 10, wherein the threshold range is within ±

20% from a reference value.

18. The standard engine cold test system according to claim 1, wherein the analysis device is configured to overlappingly display data for each of a plurality of factories for a certain type of engine to compare performance of the certain type of engine between factories.

19. The standard engine cold test system according to claim 1, wherein the analysis device is configured to visualize and display starting and rotating torques for each of plurality of engines produced in a factory.

12. A standard engine cold test method, comprising:

instructing, by a control device, a tester to perform an engine test;

driving, by the tester, a motor according to a control of the control device to operate an engine which is a test object;

measuring, by the tester, engine information depending on an operation of the engine using a sensor;

gathering, by a gathering device, the measured engine information; and

analyzing the gathered engine information to determine abnormality of the engine.

13. The standard engine cold test method according to claim 12, wherein the instructing to perform the test includes:

generating, by the control device, a measurement command depending on a user input; and

setting, by the control device, a motor starting mode depending on the measurement command.

14. The standard engine cold test method according to claim 13, wherein the setting of the motor starting mode includes setting, when the measurement mode in the measurement command is a standard measurement mode, a motor starting mode to be a standard mode.

15. The standard engine cold test method according to claim 13, wherein the standard mode setting is changed to standard driving control setting information for controlling standardized motor driving according to a kind of engine.

16. The standard engine cold test method according to claim 12, wherein the determining of the abnormality of the engine includes checking whether the gathered engine information is out of a threshold range and determining, when it is determined that the engine information is out of the threshold range, that the engine is abnormal.

17. The standard engine cold test method according to claim 16, wherein the threshold range is within ±

20% from a reference value.
