Turbocharged engine is an engine that relies on turbocharger to increase engine intake. The turbocharger is actually an air compressor. It uses the exhaust gas from the engine as power to drive the turbine in the turbine room, and the turbine drives the coaxial impeller to compress the fresh air sent by the air cleaner pipeline and send it to the cylinder.
The main function of turbocharging is to increase the air intake of the engine, thus improving the power and torque of the engine and making the car more dynamic. After the engine is equipped with turbocharger, its maximum power can be increased by 40% or even higher than that without turbocharger.
The maintenance cost is quite expensive, and the turbocharger doesn't work in most cities, because it is usually set at around 3500 rpm to start turbocharging. Moreover, the power output response of the vehicle with turbocharger is lagging, and there will be a delay when stepping on the accelerator, because the exhaust gas turbocharger needs the exhaust gas of the engine to drive it. When you step on the accelerator, the turbocharger does not improve the working efficiency immediately, and it takes more than two seconds to react.
