What is the method of turbocharging?

Turbocharging is a technology that improves the air intake efficiency of an engine by using exhaust gas to drive a turbine. Exhaust gas discharged by the engine drives the turbine to rotate at high speed, and the turbine drives the compressor impeller via a coaxial shaft. The compressed air is then delivered into the cylinders, increasing the intake air density and oxygen content, which allows more fuel to burn and significantly enhances power output. Modern technologies have led to the development of twin-turbocharging systems, where two turbines work in synergy to optimize the boosting effect at different engine speeds. Meanwhile, twin-charging technology combines mechanical supercharging and turbocharging to balance low-speed torque and high-speed power. Turbocharging not only increases power output by 30%-40% but also reduces fuel consumption by approximately 15% while lowering carbon emissions. For daily maintenance, it is essential to use high-temperature-specific engine oil (such as 5W-40 fully synthetic oil), replace it every 5,000 to 8,000 kilometres, and regularly clean the air intake system to prevent carbon buildup on the turbine blades. For instance, the locally common 1.5T engine can deliver approximately 180 horsepower, comparable to a traditional 2.4L naturally aspirated engine but with superior fuel efficiency.
