Supercharged air intake system, vehicle and method using same

Abstract

The invention discloses a supercharged air inlet system, a vehicle provided with the supercharged air inlet system and a method. The supercharged air inlet system comprises a wind concentrating device, a power turbine, an air filter and a charging turbine. The wind concentrating device comprises an air inlet and an air outlet. The air outlet of the wind concentrating device is connected with an air inlet of the power turbine. The air filter comprises an active air inlet, a natural suction port and an air outlet. The air outlet of the power turbine is connected to the active air inlet of the air filter through an airtight air conveying pipeline, so that high-pressure air is conveyed into the air filter. The charging turbine is driven by the power turbine to work; the air outlet of the air filter is connected with an air inlet of the charging turbine; and air pressurized by the charging turbine is discharged out from an air outlet of the charging turbine. According to the supercharged air inlet system, the vehicle provided with the supercharged air inlet system and the method, the air conveying pipeline is used for connecting the power turbine and the air filter in an airtight mode, so that dust accumulated inside the air filter is cleared away, air pressure inside the air filter is boosted at the same time, and working requirments for natural air suction of an internal combustion engine and working requirements of the charging turbine are met.

Description

technical field [0001] The invention relates to a supercharging air intake system, in particular to a supercharging air intake system for vehicles such as automobiles using internal combustion engines. The invention also relates to vehicles and methods using the boost air intake system. Background technique [0002] The car mainly includes five major systems: engine system, chassis system, combustion system, air intake system and electronic control system. Among them, only the air intake system has never had a major technical breakthrough in the development of the entire automobile industry, and most cars still use the traditional Naturally aspirated system (passive air intake system), only a few cars use a forced air intake system. [0003] Traditional forced air supercharging systems include exhaust gas supercharging, mechanical supercharging and electric supercharging, and their defects are as follows: (1) Exhaust gas supercharging defects: work at high temperature, comp...

AI Technical Summary

Problems solved by technology

[0003] Traditional forced air supercharging systems include exhaust gas supercharging, mechanical supercharging and electric supercharging, and their defects are as follows: (1) Exhaust gas supercharging defects: work at high temperature, complex structure, high cost, high failure rate, and safety Hidden dangers, causing engine power output delay, consuming engine power, and increasing engine fuel consumption; (2) Disadvantages of mechanical supercharging: complex structure, high cost, poor supercharging effect, consuming engine power, and increasing engine fuel consumption; (3) Electric Disadvantages of supercharging: low supercharging effect, loud noise

Due to the obvious defects above, only the exhaust gas turbocharger is currently accepted by the mainstream market, but its utilization rate is still less than 10%, and the development of this technology has spanned a century and it is difficult to popularize it.

However, this wind power supercharging device also has the following defects: unreasonable design of the drainage device, complex structure of the supercharging device and unsatisfactory supercharging effect, internal air flow of the air filter cannot meet the working needs of the engine and supercharger, and supercharging Negative pressure value of engine naturally aspirated, etc.
