Description

engine intake booster

technical field

The utility model relates to a supercharging device, in particular to an engine intake supercharging device.

Background technique

At present, the supercharging systems installed on automobiles sold on the market are generally divided into two types, one is a mechanical supercharging system, and the other is an exhaust gas turbocharging system. The supercharging system drives the rotor of the supercharger to rotate by obtaining power from the output shaft of the engine, thereby blowing supercharged air into the intake manifold. Because it is connected with the rotating shaft of the engine, part of the power is consumed, and the effect of supercharging is not high. The exhaust gas turbocharging system is the most common turbocharging device in our daily life. The supercharger has no mechanical connection with the engine. It is equivalent to an air compressor, which increases the intake air volume by compressing air. It uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and impeller speed also increase synchronously, and the impeller compresses more air into the cylinder, and the pressure and density of the air increase to burn more fuel, and the corresponding increase in fuel volume can increase the engine capacity. output power. Generally speaking, the power and torque of the engine after the exhaust gas turbocharger is installed will increase by 20%-30%. Although turbocharging can indeed increase the power of the engine, it has many shortcomings, the most obvious of which is the lag in power output response. Due to the inertia of the impeller, the reaction to the sudden change of the accelerator is slow, that is to say, there is a time difference between when you step on the accelerator to increase the horsepower, and when the impeller rotates to press more air into the engine to obtain greater power, and this time is still Not short. Generally, the improved turbocharger takes at least 2 seconds to increase or decrease the engine power output. If you want to accelerate suddenly, you will feel that you can't increase the speed for a moment. In addition, because the turbocharger is driven by exhaust gas, the temperature of the supercharged gas is high, and a cooler needs to be installed.
