This thesis is about the calculations and researches of the improved coolant system of turbocharged gasoline engine, it introduces the basic concept of gasoline engine’s turbo technology, and shows the detailed information and parameters of 486 turbocharged gasoline engine, established the formulas of the Otto cycle and its relevant parameters, emphasized to analyze the influences of the intake air temperature on the engine’s Otto cycle. The effects of the turbo gasoline intake temperature mainly contains 2 points: the outlet temperature of the turbo and the temperature decline effect of the coolant system; This thesis compares the effects of gasoline’s Otto Cycle which configures or not with a middle cooler, utilized a thermal dynamics calculation method to research, calculate and analysis the parameters of the turbocharged engine’s Otto cycle, the results are corresponding with the experiment(the thermal balance experiment), the property indices are included circulate thermal efficiency, exergy efficiency and average valid pressure. Through the contrasts and analysis, it obviously shows that, with the middle coolant, it has an advantage in the average valid pressure, intake temperature, and exergy efficiency. Absolutely it is necessary and efficient configured with middle coolant on the turbocharged gasoline engine.
