Description
Technical Field
The invention relates to the field of engine design and manufacturing, in particular to a hybrid coupling type efficient supercharging system.
Background
Turbocharging is a technique of driving an Air compressor (Air-compressor) with exhaust gas generated by the operation of an internal combustion engine (Internal Combustion Engine). Both can increase the air flow into the internal combustion engine or boiler, thus improving the efficiency of the machine, as compared to the Super-Charger function. In general, in an automobile engine, a turbocharger can increase horsepower output of the internal combustion engine by utilizing heat and flow of exhaust gas. A turbocharger system is a more efficient air intake system than conventional natural aspiration, or mechanical supercharging. Typically, it is composed of 1 or more superchargers, and the intake air amount is made larger by supercharging, thereby increasing the engine output.
Supercharging purpose: the main function of the turbocharging is to increase the air inflow of the engine, thereby increasing the power and torque of the engine and making the vehicle more powerful. After a turbocharger is installed on an engine, the maximum power of the engine can be increased by 40% or more compared with the maximum power of the engine without the turbocharger. This means that the same engine can produce more power after being boosted. In the most common 1.8T turbocharged engine, after supercharging, the power can reach the level of 2.4L engine, but the fuel consumption is not higher than that of the 1.8T turbocharged engine, and on the other hand, the fuel economy is improved and the exhaust emission is reduced.
Negative effects: however, after supercharging, the pressure and temperature of the engine are greatly increased during operation, so that the service life of the engine is shorter than that of an engine with the same displacement without supercharging, and the mechanical performance and the lubricating performance are influenced, so that the application of the turbocharging technology to the engine is limited to a certain extent.
Type of boost: a mechanical supercharging system, an air wave supercharging system, an exhaust gas turbocharging system, a compound supercharging system and the like.
Conventional coupled turbocharger systems typically place an exhaust butterfly valve at the post-vortex outlet and an intake butterfly valve at the compressor inlet. The pipe diameter at the position is larger, the size of the butterfly valve is larger, and the manufacturing cost of the butterfly valve is higher. The repositioning control has a slower effect on the response speed of the supercharger.
