I have to follow the red line exactly
Here, left and right
Yellow lines are tolerance
Lines if crossed
I have a driving error and I do all this

brakes
Of course, you don't need to change the speed
Because we have automatic

Engine test benches in service
Calendar calls crooked
Multi-day endurance race
The twin-turbo V8 engine has been modified
Firmly fixed on the test bench
Newly developed parts are developed
installed in the engine
And now they have to go through each other
Serious stress tests
Sensors up to 100 measuring points
Monitor the patient's vital signs
Because the most important point here is
Actually our brakes
In fact, it can break the motor and
Also in this case
driving it, that means we can also simulate
Race track road conditions
These things are basically everything
can you imagine
Test room fixed
Empty to avoid exhaust gases
To escape the endurance test
Boots v8 is quickly accelerated to
high speeds
Between full throttle and full braking
The engine will experience a complete experience
Life the next day
several days
The test engine is running at speeds
Between 30 and 250 kilometres per hour
While simulating the test interval
Multiple levels of resistance
The twin-turbo will be subject to it
250 hours of torture
Covering the equivalent of about 40,000
kilometres
which corresponds to 200,000 kilometres

Usually the most important point is

It's about 950 to 980 degrees Celsius

The mechanic fixes the cylinder

If its pressure ratio
Changed after endurance test
That's why it fills a graduated cylinder

The pressure ratio to be measured is
The ratio of the largest cylinder

The first combustion chamber
The cylinder is measured
To do this, the mechanic pours gasoline
So that there is no air left
