What does 1.5t mean?

[VanPaislee]

1.5t refers to the displacement of the car being 1.5 liters, indicating that the car engine is turbocharged. The 't' in 1.5t stands for Turbo, which means turbocharging. Turbocharging, or Turbo Boost, is a technology that uses the exhaust gases generated by the operation of an internal combustion engine (Internal Combustion Engine) to drive an air compressor (Air Compressor). A turbocharged engine is a type of engine that relies on a turbocharger to increase the engine's air intake. A turbocharger (Turbo) is essentially an air compressor that uses the exhaust gases expelled by the engine as power to drive the turbine located in the turbine housing (within the exhaust passage). The turbine, in turn, drives the coaxial impeller located in the intake passage, which compresses the fresh air delivered by the air filter pipe and then sends it into the cylinder. When the engine speed increases, the speed of the exhaust gases and the turbine also increases synchronously, thereby enhancing the degree of air compression. Consequently, the engine's air intake increases accordingly, allowing for an increase in the engine's output power.
