1.4T in cars refers to the engine displacement, where T is the abbreviation for turbo, meaning turbocharged. Displacement is the total working volume of all cylinders in the engine, which is the volume swept by the piston from top dead center to bottom dead center multiplied by the number of cylinders. Displacement is a crucial structural parameter that comprehensively measures the size of the engine, and the performance indicators of the engine are closely related to displacement. Here is additional information: 1. Generally, the larger the displacement of a car, the higher its power output. Unit displacement is commonly used as a basis for evaluating the size of different engines. Turbocharging is a technology that uses exhaust gases generated by internal combustion engine operation to drive an air compressor. The main function of turbocharging is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the car more powerful. 2. After installing a turbocharger, the maximum power of an engine can increase by 40% or more compared to when it is not equipped with one. This means that the same engine can output greater power after turbocharging. Taking the most common 1.8T turbocharged engine as an example, after turbocharging, its power can reach the level of a 2.4L engine, but its fuel consumption is not much higher than that of a 1.8L engine. In another sense, this improves fuel economy and reduces exhaust emissions.
