What are the advantages and disadvantages of turbocharged engines?
2 Answers
Turbocharged engines have the following advantages and disadvantages: Advantages: Effectively utilizes the exhaust energy of the engine to provide boost for the intake system, resulting in good energy-saving performance. Disadvantages: Insufficient exhaust energy in the low RPM range leads to less noticeable boost effects. Turbocharging only becomes apparent after reaching a certain RPM, causing a delayed and inconsistent acceleration feel. Additional information: Main functions of turbocharging: Increases the engine's air intake, thereby enhancing its power and torque, making the vehicle more powerful. On another level, it 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 while significantly increasing power without a substantial increase in engine size. The downside is slower acceleration response and less linear and smooth operation.
I've been driving a turbocharged car for five years, and the most noticeable feeling is that the power comes on very strong when I step on the throttle, especially when overtaking on the highway, which gives me a lot of confidence. However, the throttle feels a bit sluggish at low RPMs, making it easy to get cut off in traffic jams. The technology has improved a lot now; for example, my friend bought a new car last year, and the turbo engagement is quite smooth. Maintenance requires attention to full synthetic oil and timely changes, as turbos are sensitive to high temperatures and impurities. When buying a used car, you need to pay attention to the turbo's condition, as replacing one can cost several thousand. Overall, I still prefer turbocharged cars—small displacement can deliver the acceleration feel of a larger engine, and they also offer advantages in terms of environmental friendliness and purchase tax.
