What are the three functions of a turbocharger?

The three main functions of a turbocharging device are to increase the engine's air intake, thereby enhancing the engine's power and torque, making the vehicle more powerful. Below is additional information: Disadvantages of turbocharging devices: 1. Lag in response: The inertia of the turbine wheel causes a delayed response to sudden changes in throttle, meaning there is a time lag between stepping on the accelerator to increase power and the turbine wheel spinning to force more air into the engine for greater power. Even with improved turbocharging, it takes at least about 2 seconds to increase or decrease the engine's power output. Therefore, vehicles equipped with turbochargers have a driving experience that is somewhat different from those with naturally aspirated large-displacement engines. 2. Effects of high temperatures: After pressurization, the pressure and temperature during engine operation significantly increase, leading to a shorter engine lifespan compared to naturally aspirated engines of the same displacement. Additionally, mechanical performance and lubrication performance are affected. 3. High maintenance costs: Maintaining a turbocharged engine is more expensive than maintaining a naturally aspirated one.
Speaking of that turbocharger box, it took me quite a while to fully understand it through my car modding experience. The turbo housing has three core functions: First, it compresses intake air by using exhaust gases to drive the turbine blades, forcing more air into the cylinders. Second, it boosts the engine's overall power output—compressed air has higher density, allowing more fuel combustion and significantly enhancing acceleration kickback. Third, it helps improve fuel efficiency, especially in small-displacement engines, by recycling exhaust energy to save fuel and reduce emissions. I recently installed an upgraded turbo and noticed quicker acceleration on highways without much increase in fuel consumption. But maintenance is key—regularly check the intake pipes to avoid clogs. This thing really lets the car 'breathe' better, like giving the engine a performance booster.
