This time, we visited with "hybrid technology" turbine industry in Taiwan played visibility "Cadillac turbine." "Hybrid" meaning actually like breeding theory of eugenics: "combines the advantages of both, to create a more excellent the next generation." Disguised perspective, take into account the running accuracy, fuel consumption, durability and other factors, turbo cartridge replacement "the original turbo" upgrade space and of course, the original small turbo although low speed reaction is good, but the capacity is quickly filled, turbo pressure has reached its limit, causing the air to the lack of efficiency, would like to improve the horsepower with the engine speed is really very reluctantly.
Conversely, if you want to play at a high speed before the big horsepower, by increasing the volume to boost turbocharger turbine wind is the fastest way. However, the greater the capacity of the turbine, although capable of the more air into the cylinder, but the engine is required to drive the large turbo also requires greater displacement. Therefore, if the use of large turbine on a small displacement engine, boost the value of low-speed region is difficult to upgrade, blade speed down it is difficult to instantly picked up, which is commonly known as "turbo lag (Turbo Lag)." To solve the above contradiction, "hybrid turbo" came into being, I hope boost the value in the same circumstances, but has the advantage of large turbine-powered reaction advantages and small turbine.
Hybrid turbo mainly "big intake end of the blade," with the "small exhaust end of the blade," may take into account the performance of the full speed of the domain. With HKS 2530, for example, Turbo Cartridge is by the intake vanes A / R80 fit A / R60 intake side wheel shell composed, but this match if too extreme, too much pressure discharge will occur, resulting in destruction of the blade capacity situation, but fortunately this problem can wastegate, large diameter exhaust pipes, and even high-strength titanium alloy blade solution (its lightweight nature of the reaction of the turbine is also helpful).
But in the so-called Taiwan modified community "hybrid", mostly medieval turbine dismantling reorganization, but also because of the use of medieval goods reprocessed, so advance "repair process" is very important. Basically, the probability of a broken turbo snail shell is very small, because reprocessing is to increase the discharge aperture turtles, the most common injury is often where the impeller, bearings and seals. Section bearings and oil seals relatively simple, basically as long as the oil spill situation occurs, direct buy "service pack" and replace, but apart from the impeller blade deformation part, damage and other problems, the blade itself forming process also because of metal density distribution when not all, and in operation the blade (12000rpm above) eccentric to the jitter, particularly the combination can maintain the balance of the turbine impeller, the purpose of the impeller balance test is to test the difference between the mass of the blade, and the high quality of the cut away portion. In short, as long as through the "finishing" Middle turbine than can look, but also the way to increase the intake side of the specifications.
