The boost system of a modern engine still causes a lot of controversy, even among experienced “steersmen”. This causes errors that lead to unit failure. The AvtoVzglyad portal tells about the most popular bicycles that car owners should not believe.
The first misconception is related to the exhaust gas recirculation (EGR) valve. Many muffle it, because the knot is often clogged with soot and deposits. It is believed that this will destroy the turbine, since after such work the temperature of the exhaust gases rises, as a result of which the unit heats up greatly. However, the degrees grow much faster in the “throttle to the floor” mode and nothing breaks. So safely switch off the EGR. There will be no consequences.
Next story: the boost only works in a certain rev range. This is because the supercharger is always active from the moment the engine is started and does not function as an on/off switch. That’s just the effect felt from a certain moment. This moment in each engine is different. Hence the prejudice.
Many people think that a car with a turbo consumes more fuel. This is only partly true. Modern units are made precisely to save fuel. After all, the working volume of such an engine is smaller, and the power, in comparison with “aspirated”, is comparable. So at city speeds, the hunger for “supercharging” is modest.
The blades of the “snail” can burn if you drive at high speeds for a long time: another “horror story” that motorists have nightmares about. In fact, when the engine can be serviced, there will be no such problems, because it is designed to “live” in difficult conditions. And if you did a “bad” chip tuning, and then erased the errors that arose with a scanner, then this happens. But this is not the fault of the technology.
Finally, there is an opinion that boost reduces reliability, and therefore the resource. The fact is that such a unit has a complex structure, and its internal loads are quite high. But engineers design the engine with these features in mind, and the compressor parts are specially reinforced. So a modern engine will last just as long as an “aspirated” engine. And if the supercharger breaks down, there’s a repair kit for it. So you don’t have to change it completely.
