Synergistic turbocharger with gradual change air flue

Abstract

The invention discloses a synergistic turbocharger with a gradual change air flue. A lower gradual change air flue is divided into a left intake gap and a right intake gap by a lower air flue partition board in a turbine shell, an upper gradual change air flue is divided into a left exhaust gap and a right exhaust gap by an upper air flue partition board, and the width of the left exhaust gap is greater than the width of the left intake gap; the width of the right exhaust gap is greater than the width of the right intake gap; in a gas compressor, the width of an upper air outlet is equal to the width of a lower air inlet. Owing to redesign of the intake gap and the exhaust gap of the upper gradual change air flue of the turbine shell to the turbine, the intake gap at the starting end is smaller than the exhaust gap of a terminal, the push pressure of the intake starting end of the turbine shell is increased, the exhaust pressure of the terminal is reduced, and the output power of the turbine is improved. Through changing the sizes of the intake gap of the gradual change air flue on a pressing shell and the exhaust gap of the terminal, the intake gap of the starting end is greater than the exhaust gap of the terminal, the oxygen density in the output compressed air is improved, and supercharge and oxygenation performances of the turbocharger are improved.

Description

【Technical Field】 [0001] The invention relates to a turbocharger, in particular to an exhaust-type turbocharger. 【Background technique】 [0002] Exhaust turbocharger uses high-temperature and high-temperature exhaust gas discharged from an internal combustion engine as a power source. The high-temperature and pressure exhaust gas discharged from the internal combustion engine is introduced into the turbine in the turbocharger, and the energy contained in the exhaust gas is used to drive the turbine in the turbine to rotate, thereby driving the turbine Rotation, while driving the coaxial compressor impeller to rotate, the compressor will compress and boost the intake air to the intake system of the diesel engine, filling the internal combustion engine cylinder with high-density air, which can increase the fuel injection volume per time , It can not only increase the output power of the same type internal combustion engine, but also significantly improve the economy of the internal...

AI Technical Summary

Problems solved by technology

[0004] In the existing exhaust-type turbocharger, the structure of the turbine shell 1 in the turbine and the pressure shell 8 in the compressor is unreasonable. In the gradual change air passage of the turbine shell 1, the air outlet gap directly leading to the turbine is designed This structure can neither increase the intake pressure at the intake end of the turbine shell nor reduce the exhaust pressure of the turbine. The pressure difference between the intake end and the exhaust end of the turbine has not been maximized. Under these conditions, the further improvement of the output power of the turbine is affected, and the structure design of the air outlet gap directly affects the output power of the turbine

Similarly, the fit gap structure between the booster impeller and the pressure shell in the compressor also directly affects the output compressed air density of the compressor, thereby affecting the improvement of the turbocharger's supercharging effect
