What does E/T mean on a car?

[LondynLynn]

E: Stands for the engine using an electronically controlled fuel injection system. T: Represents Turbo, meaning turbocharging. The principle and function of turbocharging are introduced as follows: Principle of Turbocharging: A turbocharged engine relies on a turbocharger to increase the engine's air intake. The turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller compresses the fresh air delivered through the air filter pipe and then sends it into the cylinders. As the engine speed increases, the exhaust gas flow rate and turbine speed also increase synchronously, thereby enhancing the air compression level. This results in a corresponding increase in the engine's air intake, which boosts the engine's output power. Function of Turbocharging: The main function of turbocharging is to increase the engine's air intake, thereby improving the engine's power and torque, making the car more powerful.
