Was mir dabei allerdings fehlt ist die Einstellung des Motorenprogramms, das ebenfalls einen Einfluss haben sollte.

Wobei es auch schwierig ist, das zu pauschalisieren, weil weissgott nicht alle Autos gleich reagieren..... Schwierig, schwierig.....

Was gäbe mehr Frust, als nach 1,5 Stunden in den Rückspiegel zu schauen, und die Rauchwolke des eigenen Motors zu sehen ?!?!?!

The engine lifetime calcs are as follows:

LifetimeEngineRPM=(<baseRPM>,<halfLifeRPM> )
LifetimeOilTemp=(<baseTemp>,<halfLifeTemp> )
The expected "lifetime" of a vehicle engine in rFactor is described as a certain amount of time running at normal operating conditions, which consist of an RPM and a temperature. If those two values were constant at <baseRPM> and <baseTemp>, and we temporarily neglect the effects of boost settings and ram-air, then the engine would last approximately LifetimeAvg +/- LifetimeVar seconds (both parameters described below) before blowing up.

Obviously, those two values are rarely constant, especially with the RPM fluctuating constantly in most racing environments. And the engine "wear" (the progression through the engine's lifetime) is related exponentially to the differences between the actual RPM and actual temperature vs. the <baseRPM> and the <baseTemp>. Specifically, if the actual RPM equals <baseRPM> + <halfLifeRPM> and the actual temperature equals <baseTemp> + <halfLifeTemp>, then the engine wear will occur half as fast (Anmerkung von mir: muss wohl 'twice as fast' heißen). Another way of saying it is that the lifetime is now cut in half.

The precise equation averages the two wear rates (the RPM "wear" and the temperature "wear" ). So if the actual RPM equals <baseRPM> + <halfLifeRPM> but the actual temperature is exactly <baseTemp>, then the current wear is 1.5, meaning a reduction in lifetime of 33%.

So for every increase in RPM of <halfLifeRPM>, the wear rate doubles: At <baseRPM>, the RPM wear is 1.0. At ( <baseRPM> + <halfLifeRPM> ), the RPM wear is 2.0. At ( <baseRPM> + ( 2.0 * <halfLifeRPM> ) ), the RPM wear is 4.0, etc. The same goes for temperature increases.

Note that engine wear does *not* affect performance in any way, until, of course, the engine blows up. At that point the engine will be at least partially damaged or completely unusable, depending on how stressed the engine was as it died.

LifetimeAvg=<average>
LifetimeVar=<variance>
The actual engine lifetime is computed randomly on a bell curve, with a normal variation centered on <average> and a standard deviation of <variance>. In other words, approximately 68% of engines will last somewhere between ( <average> - <variance> ) and ( <average> - <variance> ) under normal operating conditions. And approximately 95% of engines will last between ( <average> - ( 2.0 * <variance> ) ) and ( <average> + 2.0 * <variance> ). Of course staying constantly at exactly the normal operating conditions is nearly impossible. Please see the LifetimeEngineRPM and LifetimeOilTemp parameters described above for how the engine's lifetime is progressed through.

am einfachsten macht man es sich, indem man das XD-Tool installiert.
Das zeigt einem von Anfang an, wie viel Motor "noch übrig ist"
So spart man sich die Rechnerei und kann btw gleich beim Start sehen, wieviel Varianz man bekommen hat. Wenn also der Zufall will, daß man nur mit 70% am Start steht, kann man nochmal schnell in die Box und es nochmal probieren...

Aber macht euch darum nicht so viele Sorgen, bei schonender Fahrweise, d.h. Begrenzer etwas runterdrehen bzw den Motor nicht immer ausdrehen und vor allem nicht erst schalten, dann bremsen, sollten die Kisten die vier Stunden lässig durchhalten.

Ich freu mich ja drauf, daß einige notorische Motorquäler diesmal nicht ankommen werden )))
