Abstract :
To improve transient response of turbocharged gasoline, various kinds of optimization methods were studied by using engine performance simulation software GT-POWER. The results showed that: increasing valve overlap, using the series composite supercharge and replacing the original turbocharger with a VNT turbocharger can improve transient response characteristics of the original supercharge engine, when using the series composite supercharge, transient response of turbocharged gasoline hardly has any "hysteresis" phenomenon.
