Take you to understand what is a turbocharged engine

Turbo is referred to as Turbo. If you see Turbo or T at the rear of the car, it means that the engine used in the car is a turbocharged engine. I believe that everyone has seen many such models on the road, such as Audi A6 1.8T, Passat 1.8T, Bora 1.8T and so on.

A turbocharger is actually an air compressor that increases intake air by compressing air. It uses the inertial momentum of the exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipeline to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the speed of the wheel also increase synchronously, and the impeller compresses more air into the cylinder. The increase in the pressure and density of the air can burn more fuel, and the corresponding increase in the amount of fuel can increase the engine. output power.

The biggest advantage of the turbocharger is that it can greatly improve the power and torque of the engine without increasing the engine displacement. Generally speaking, the power of the engine after the supercharger is installed And the torque should be increased by 20%-30%. The disadvantage of the turbocharger is the lag, that is, due to the inertia of the impeller, the response to the sudden change of the throttle is slow, so that the engine delays to increase or decrease the output power. a feeling of.
