The WGV mechanical operating characteristics, which affect the power performance of a WGT gasoline engine, were studied to further understand how it affects the latter. For this purpose, the behavior of the WGV was established according to the engine operating conditions, and as the engine power performance affects the WGV opening time, the duty control and deterioration rates were experimented on. To sum up the main study results, the WGV vibration properties were rapidly repeated during the operation. The head of the WGV started to be opened from an at least 45 % throttle load through the whole engine rpm, and the engine load conditions of the WGV opening time gradually increased at up to a 75 % throttle load. The maximum duty control rate was kept at 100 % until about 2,000 rpm, and it gradually decreased until 4,000 rpm but sharply increased again in a region of a very high engine speed of WOT. At these engine operating conditions, the engine torque rapidly decreased because of the decrease in volumetric efficiency. These resulted from the increased engine cooling and exhaust gas losses at a high combustion temperature. Wear of the WGV head and housing seat was observed during the WGT engine endurance test. This led to a decrease of the boost pressure, which directly caused a decrease in the power output of the WGT gasoline engine.
