It was studied on the understanding of the operating characteristics of WGV which effected the power performance in a WGA gasoline engine.
At first, according to engine operating conditions, the mechanical behavior of the WGV was established for this purpose. And the effects of the engine poser performance on WGA opening time, WGV duty control rate and the and the deterioration of WGV head were tested and experimented.
To sum up the main results, the vibration of operating characteristics of WGV was rapidly iterated during the opening time. WGV started to open it`s head from over at least 45% throttle load through the whole engine RPM, And the load conditions of WGV`s opening time increased gradually up to 75% throttle load, Until about 5,0000rpm, maximum duty control rate was kept 100% duty rate. And it was gradually reduced down at the increased speed and load, but it dropped sharply at a very high speed of WOT.
At these engine operating conditions, because of the decrease of volumetric charging efficiency, the engine torque was rapidly decreased. These were resulted from the increase of engine cooling loss and exhaust gas loss at a high combustion temperature. And the wear of WGV head and housing seat was observed during an endurance test of WGT engine. It led to result in cause of decrease of a boost pressure which directly caused the power output decrease of WGT gasoline engine.
