+MrWafflez000There are two sets of blinkers on a car. One set of them is on the front- and taillights, and the other ones are on the both front fenders.
How do real manufacturers test the durability of an engine? I know they
have all these mechanisms and rigs to test certain parts like suspensions
and seatbelt clicky things for durability... But I can't imagine how they
can test an engine for it? Would there just be a rig that has the engine
revving up and down till it reaches a certain milage that they're happy
with without breaking anything? Because putting that many miles on an
engine takes a loooong time and a loooott of fuel, even if it runs day and
night? Especially since an engine does kinda require a ton of filter, oil
and sparkplug changes, even for just gaskets to get to the end of their
lifecycle...
Or are they experienced enough that they just know how to build the engine
in a way that it lasts at least 130k with just sparkplugs and oil changes?
A big part of it is maths, all the internal forces and temperatures are worked out to avoid any surprises.Then its a case of testing to see if anything has been missed, and that is a case of reving up and down, hard starts from cold and all kind of abuse.Often the testing is done in prototype of it's home to see how it handles live in it's home.
They have many people that do the math to find out how to get the most out of the engines.Most companies these days don't even make their own engines because their so expensive to design, and to put into production
