Objective
After using this method to test the success of about 300 new engines, and without any problems, I wrote the article "Running-in in."
The link to this article is that there are so many motor vehicle movements around the world (Motorsport) altar because a lot of people in this time are comparing my way directly to the way the main car is registered, and the news of their success spread quickly.
The results are always the same-dramatic increases the force of the full speed field, in addition, many professional technicians break down the engine that is used in this way, and they discover that the engine is actually better than the traditional way of using the car Master manual.
The reason this is so controversial is that this article is contradictory to this article from some of the previous references to running-in articles.
There are a couple of factors that make the old information about running-in obsolete, the biggest factor is that the engine maker has used more elaborate abrasive paths (honing pattern) on the cylinders than before, thus changing the requirements of running-in, which, as everyone will learn later, can complete the excellent piston ring seal. will be much shorter than the old rough grinding (Rough horned) engine.
In addition, because of the more delicate abrasive paths of the modern engine, the heat produced by the piston ring friction on the cylinder wall will be much less.
Other factors that have changed are the use of the metal cast and processing techniques that are now being used, which means that the friction and attrition of new parts is significantly lower than in the past.

How to break into your engine to make it more horse-resistant and less abrasive.
One of the most critical procedures in the process of building an engine is running-in. No matter how good the engine is, the last thing you can do is decide what you will do.
While the example here is the motor vehicle engine, these standards are suitable for all four travel engines:
Street, Race (machine) cars, cars, snow cars, aircraft ... Even a lawn mower. (regardless of factory license, cold system type, cylinder numbers)
These running-in techniques also apply to iron cylinders, 鎳 silicon carbide (Nikasil) cylinders, and ceramic cylinders used by Yamaha in vehicles and snow cars.
=====================================================
What's the best way to get into the new engine?
In simple words: do it hard.
why.
Now, the running-in process is the sealing of the piston ring, unlike most people know, the piston ring is not the pressure of its own to seal the explosion in the burning chamber, the piston itself is only needed for scraping, to avoid the engine oil into the burn chamber.
Let's think about it, the piston ring acting on the cylinder wall may only have 5~10 pounds, so how can such a small force seal the PSI's explosive pressure. Of course it can't be sealed.
How the piston seals the huge explosion pressure.
It is by this huge gas pressure itself. This pressure passes through the piston's rim, to the piston's inner side to the cylinder wall, and the problem is that the new piston ring is not perfect, they have to be in the process to completely seal the cylinder wall, if at the beginning of the new engine has sufficient pressure (such as the instantaneous oil door full), the piston will be complete with the cylinder running-in, Seal the pressure of the explosion as possible.
Temperature and running-in (easy to break in) problem ...
The Cross type abrasive path (honed Crosshatch pattern) on the cylinder wall is like the file of the knife and the piston loop, and whether or not the engine is running, the piston ring will quickly Lu Yiping these uneven textures.
In fact, only a very short time can make the piston ring really good, at the beginning of the new car 30 kilometers.
If the piston is not forced into the cylinder wall as quickly as it can, the texture on the piston wall is flattened before the piston is fully closed, and once this happens, there is no other way except to grind the cylinder wall and replace the new piston loop.
Well, most of the new owners can't resist the little driving a couple of trips, which is why most engines don't have this problem.
Another factor you may not be aware of is that the dealership mechanic who helped you set up your new car is likely to have a hard time with you when you try to ride the Test Run. So in the case of ignorance, it's a big help to have the kidney of the glandular-mad mechanic.
=====================================================
Now tell you what to do:
There are three ways to use the Running-in engine:
On the horse test machine.
Street, or not on the street (off-road vehicles or snow cars). (It's not nonsense, it's off road, everybody knows it.)
