What are the three types of turbos?

Turbocharging technology is mainly divided into three core types: mechanical supercharging, exhaust gas turbocharging, and pressure wave supercharging. Its advantages include fast and linear power response, but it consumes part of the engine power, and it is commonly used in 3.0T engines of models such as the Audi A6L. Advanced technologies such as low-inertia turbines (Toyota Corolla 1.2T) and variable geometry turbines (Porsche 911) can mitigate this issue. Pressure wave supercharging relies on exhaust gas pressure waves to compress air; it delivers excellent supercharging performance but is bulky, making it primarily suitable for diesel-powered industrial vehicles. Additionally, compound supercharging systems (e.g., mechanical + exhaust gas dual supercharging) combine the benefits of both technologies, but their complex structure and high cost limit their application to high-performance models. Turbocharging technology enhances the power output of small-displacement engines-for instance, a 1.8T engine can match the performance of a 2.4L naturally aspirated engine while maintaining fuel efficiency. However, adequate heat dissipation under high loads and regular maintenance are essential to prolong its service life.
