1. The displacement of 1.5 refers to the volume of fluid inhaled or discharged by the cylinder per stroke or cycle. The larger the displacement, the higher the power. With large displacement, the energy released by the engine per unit time (that is, the chemical energy of the fuel is converted into mechanical energy) is large, which means good power performance. In the current automobile market, the displacement of vehicles is divided into 1.5T and 1.5L.
2. 1.5L: The displacement of 1.5L engine is the sum of the working volume of each cylinder of the engine, which is the volume swept by the piston from TDC to BDC times the number of cylinders.
3. 1.5T: T stands for turbocharging, short for Turbo. It refers to the 1.5L engine with intake turbocharging device, which is derived from 1.5L engine plus turbine.
