Instruction and Operation
Road Test or Rolling Testing Platform
Test
In many cases, the road test or rolling testing
platform test is required to for the automobile. The
detailed instructions of checking procedures before
relevant test are illustrated as follows, from the
engine starting and stopping, the check before
driving, the check during the test to the final check
after testing.
After only when the tests of all performances are
completed, the road test of the automobile can be
performed. However, the selective testing is
performed for the checked items in connection with
the system.
Check before Testing
Warnings: If the pressure of the braking
system is lower, the stroke of the braking pedal
is too large or the leakage exists in the hydraulic
system, the road test is prohibited. After the
problems are found and rectified, the road test
can be performed.
It is suggested that before the road test is performed,
the test be performed at first before the inspection.
The functional test is performed for those
influencing the automobile safety driving
system/circuit, such as the brake, the vehicle lamp
and steering, etc.
Start the engine
Notes: Within the time of the initial starting of the
cold engine or the initial 1.5 km, before the
automobile driving speed reaches 25 km/h, the
accelerator pedal does not exceed half of the stroke.
Do not operate the engine at the high speed during
the refrigerator car, or the accelerator pedal is
stepped to the last.
Close the ignition system and Check:
– Apply the parking braking.
– Check whether the transmission lever is at the
neutral position
– Check whether the pointers of all the
instruments (except the fuel gauge) point to
Zero.
Turn on the ignition switch and confirm:
– Confirm whether the indicating lamp of the
ignition switch is bright.
– Confirm whether the engine temperature
pointer has the correct reading.
– Confirm whether the reading of the fuel
pointer conforms to the fluid level of the fuel
tank.
– Display the manual brake caution lamp and
the fluid level caution lamp.
– During the Road Test or the Rolling
Testing Platform, inspect:
Warnings: During the road test, the
braking system shall be checked when the
driving speed of the automobile is slow. If
the brake derivation or other problems
exist, please find out the problems and
modify them, and before the problems are
solved, prohibit the vehicle to be started.
– Step on the clutch pedal easily.
– The low gear meshing and the clutch
connection are stable.
– The manual brake operation is flexible, and
the releasing of the manual brake is rapid and
thorough.
– The fluid level of engine oil.
– The fluid level of engine coolant.
– Check whether the tyre air pressure is qualified,
the mode and the pattern are applicable and the
abrasion limitation is exceeded.
– Check whether the sufficient fuel used for road
testing exists in the fuel tank.
– Check whether the oil leakage (the engine oil,
hydraulic oil and fuel) and water leakage exist
around the engine and the transmission gear and at
the bottom of the vehicle. Write down the possible
leakage positions and the vicinal area is wiped
cleanly, and thus the leaking degree can be easily
checked after the test is finished.
