It turns out that rotary engines of the Wankel are just two of the most common diseases
From the rotary engine can be two problems: with the indigenous bearing and seals
I’m sure almost everyone has heard about the rotary engines Wankel. Many motorists know that they have a number of advantages: they are more powerful than classical internal combustion engine under equal working volume, they have fewer moving parts, they are easier… However, these power units have negative traits such as relatively small mileage of high costs, complexity of production due to the need for very high precision elements of the engine, Jora oil and consumption of gasoline.
But what really few people know is the fact that the most important part of all balanced rotor system are the so-called corner seals, through which the engine holds compression, into the chamber inlet combustion and release (in the Wankel engine are three different camera) does not get the oil and the motor has to work. So, the internal parts of the rotary engine literally can fall apart because of this small part:
Interestingly, if you look at the history of the formation of a rotary motor in the form of the production model, you can see a number of interesting facts. For example, it is because of these absolutely insignificant at first glance, seals the first company to set up production of rotary power units the German NSU, went down, and never recovered from pursuing her failures with the reliability of engines. But the second company is from Japan and her name was Mazda able to simplify the design, achieving improvement of reliability:
The problem was to seal the top of the rotor – thin strips of metal between the tips of rotating rotor housings and rotors. NSU made of three layers, which caused uneven wear. It was a time bomb not only for cars, but also for the automaker. Mazda has solved the problem of seals, making them single layer. The power unit began to set in 1967 on the sports luxury model Cosmo…
However, the pig in this rather capricious engine can enclose not only the seal. In the video below (alas, it is in English, so if you are taught English in school, you’ll have to take our word for it) you can see that in one of the rotors cranked the bearing, which is very, very bad thing. It is extremely loaded part that holds the center of the rotor on the shaft, so if it fails, the engine will almost certainly you can get it repaired. As with the failure of the seal leads to oil starvation. Mota on a mustache, if you drive a Mazda RX-8:
