What are the intervention conditions of automobile turbocharger? There are still many people who still see the engine speed when using the maximum torque in the car parameters, and still use the turbine of the car when using the turbocharger. When the supercharger starts to work, the higher the rotational speed, the greater the exhaust pressure, and the greater the pressure that can drive the turbine to run. Due to the low exhaust gas velocity and pressure, the pressurization effect is not obvious. The supercharging effect of the turbocharger is basically proportional to the previous rotation speed, and it will start to work when it is started.

Does the turbocharger start to work after the car is started? The maximum torque speed is in this speed range, and the engine torque output reaches the maximum value, instead of the speed turbine starting to work. (What does torque stand for? The working principle of turbocharger is that the exhaust gas discharged when the turbine blades rotate is driven by the operating power, and the air intake of the engine increases, thus increasing the torque and power of the engine.

The turbocharger changes the early lag, and the power output and torque output are very linear. As shown in the figure, it can be seen from the dotted line that the torque before 1500 ring increases, and the maximum torque output remains in the range. If the turbocharger starts to intervene in the transfer of 1500, the torque output will not increase linearly.

A single turbocharger is limited by the low exhaust speed at low speed, and the maximum pressurization at high speed is limited by the turbine itself. The application of double turbochargers further provides short steering of single turbocharger, low pulley lift, less exhaust gas to drive small turbine to generate sufficient intake pressure at high speed, and some small-displacement turbocharged engines can reach the maximum torque output at very low speed, because the turbine and the large turbine begin to intervene to ensure high-speed power output.
