1. An internal combustion engine test system equipped with a plurality of test devices including an exhaust gas line for sampling exhaust gas discharged from an internal combustion engine, the system comprising:
- a system status display part adapted to display a schematic diagram of the internal combustion engine test system including a plurality of symbols each representing one of the test devices and a corresponding connecting aspect thereof on a screen; and
an operating condition acquisition part adapted to acquire data indicative of operating conditions of combinations of the test devices,wherein the system status display part is further adapted to determine that the data indicates abnormal operating conditions for a set of the test devices and, in response to the determining, change, visual aspects of the symbols representing each of the test devices of the set, without changing an entirety of the screen, to indicate a change in degree of operation safety associated with the set of the test devices.

8. A computer program, for an internal combustion engine test system equipped with a plurality of test devices including an exhaust gas line for sampling exhaust gas discharged from an internal combustion engine, stored on a non-transitory computer readable medium that when executed by a computer causes the computer to exert functions of:
-
an operating condition acquisition part adapted to acquire data indicative of an operating condition of each of the test devices; and a system status display part adapted to display on a screen a schematic diagram of the internal combustion engine test system including a symbol representing each of the test devices and a corresponding connecting aspect thereof, wherein the system status display part is further adapted to determine that the data indicates abnormal operating conditions for a set of the test devices and, in response to the determining, change visual aspects of the symbols representing each of the test devices of the set, without changing an entirety of the screen, to indicate a change in degree of operation safety associated with the set of the test devices.

9. An internal combustion engine test system equipped with a plurality of test devices including an exhaust gas line for sampling exhaust gas discharged from an internal combustion engine and a shut-off valve provided on the exhaust gas line, the system comprising:
-
a system status display part adapted to display a schematic diagram of the internal combustion engine test system including a plurality of symbols each representing one of the test devices and a corresponding connecting aspect thereof on a screen; and an operating condition acquisition part adapted to acquire data indicative of operating conditions of combinations of the test devices including a valve opening/closing status that indicates an operating condition of the shut-off valve, wherein the system status display part is further adapted to determine that the valve opening/closing status indicates an abnormal operation condition and, in response to the determining, change visual aspects of the symbol representing the shut-off valve and the exhaust gas line connected thereto to indicate a change in degree of operation safety associated with the shut-off valve.
