[0002] In today's rapid development of the ship industry, the development of marine engines is even faster. Marine engines are developing towards high power, high energy efficiency and low fuel consumption. Marine engines necessarily increase the supercharging pressure, so that more air enters the combustion chamber, so that more fuel can be completely burned, further increasing the power density, which has great advantages for improving the power of internal combustion engines. However, high supercharging will increase the exhaust pressure, thereby increasing the pumping loss during the exhaust stage, and may also cause greater turbo lag.

[0003] Its response is slow because it needs a certain exhaust flow to start operating, so it cannot fully play its role in supercharging when the engine speed is low. In addition, the engine needs to consume part of the energy to drive the turbine. Due to the complex structure and highly precise manufacturing process, the maintenance cost of the turbocharger is also high. SUMMARY

[0004] In view of the shortcomings of the prior art, the present application provides an exhaust gas supercharging release system of an internal combustion engine, which solves the problems of slow response, high exhaust pressure and high maintenance cost of the turbocharging system in the prior art.

With the following beneficial effects: 1、The present application through the two exhaust valves after the gas is fully expanded, the exhaust gas is discharged into the inside of the exhaust passage, and the exhaust gas is delivered to the turbine driven turbine to drive the rotor shaft to drive the compressor, so that the compressor pressurizes the incoming air, and the pressurized air enters the inside of the intake cooler to cool the air, and is delivered to the inside of the intake passage, so that the turbine quickly responds and the thermal efficiency of the internal combustion engine is improved.
