Turbocharger is a common power boosting device in modern automotive engines, which increases intake pressure by utilizing the energy of the engine's exhaust airflow, thereby increasing the engine's output power and torque. However, if the turbocharger malfunctions or is damaged, it will have a negative impact on the engine.

A damaged turbocharger can reduce the output power and torque of the engine. This is because the main function of a turbocharger is to increase intake pressure, thereby increasing the combustion efficiency of the engine and generating more power and torque. If the turbocharger malfunctions or is damaged, the intake pressure will decrease, resulting in a decrease in engine output power and torque.

Damaged turbochargers can reduce the fuel economy of the engine. The function of a turbocharger is to increase intake pressure, thereby improving the combustion efficiency of the engine and correspondingly reducing fuel consumption. If the turbocharger malfunctions or is damaged, the intake pressure will decrease, leading to a decrease in combustion efficiency and an increase in fuel consumption, thereby reducing the engine's fuel economy.

Damaged turbochargers can increase the engine's emission levels. The function of a turbocharger is to increase intake pressure, thereby improving the combustion efficiency of the engine and correspondingly reducing the amount of exhaust emissions generated. If the turbocharger malfunctions or is damaged, the intake pressure will decrease, leading to a decrease in combustion efficiency and an increase in exhaust emissions, thereby increasing the emission level of the engine.

In summary, a damaged turbocharger will have adverse effects on the engine, such as reduced output power and torque, reduced fuel economy, and increased emission levels. Therefore, car owners should pay attention to the maintenance and upkeep of the turbocharger during daily use of the car, and promptly detect and eliminate faults to ensure the normal operation of the engine.
