Study of titanium aluminides turbocharger casting
It is a widely use of titanium alloys in the industrial production fields because of their unique high strength-weight ratio, fracture resistance, and superior resistance to corrosion. An increasing number of companies prefer to use Titanium alloy TC11 instead of TC4 in manufacturing impellers an...Read more -
Study note of turbo turbine housing
Improvements in the efficiency of internal combustion engines has led to a reduction in exhaust gas temperatures. The simultaneous tightening of exhaust emission limits requires ever more complex emission control methods, including after treatment whose efficiency is cru...Read more -
Some information about turbocharger
Turbo-discharging is a novel approach that can better utilize the energy recoverable by a turbine mounted in the exhaust flow of internal combustion engines. The recovery of blow down pulse energy in isolation of displacement pulse energy allows the discharging of the exhaust system to reduce eng...Read more -
Studying note of VGT turbocharger
All compressor maps are evaluated with the help of the criteria derived during the requirements analysis. It can be shown that there is no vaned diffuser which increases compressor efficiency in the main driving range while maintaining the baseline surge stability and efficiency at rated engine p...Read more -
