What are the disadvantages of a turbocharged engine?

[ErinFitz]

Turbocharged engines have the following advantages and disadvantages: 1. Advantages: Effectively utilizes the exhaust energy of the engine to provide boost for the intake system, resulting in good energy-saving effects. 2. Disadvantages: In the low-speed range, the exhaust energy is insufficient, and the boost effect is not obvious. The turbocharging intervention can only be felt after reaching a certain speed, leading to a delayed and inconsistent acceleration feeling. Below is additional information: The main function of turbocharging is to increase the engine's air intake, thereby improving the engine's power and torque, making the car more powerful. On another level, it also improves fuel economy and reduces exhaust emissions. When properly matched and operating under conditions where the turbo is generating positive pressure, it can reduce emissions and exhaust noise, significantly increasing power without a substantial increase in volume. The disadvantages are slow acceleration response and less linear and smooth operation.
