What does 300TGI mean?

[RhettMarie]

300TGI's 300 refers to the rounded number of the 1.5T displacement engine with a maximum torque of 275 N·m, and TGI stands for the engine's in-cylinder direct injection technology. Below are the relevant introductions: 1. Introduction one: In order to achieve the goal of energy saving and emission reduction, automobile manufacturers are developing technologies aimed at improving fuel efficiency, and the intelligent in-cylinder direct injection TGI is one of the most representative technical items. 2. Introduction two: The so-called in-cylinder direct injection is to install the fuel nozzle in the cylinder and directly inject fuel into the cylinder to mix with the intake air. The injection pressure is further increased to make the fuel atomization more refined, truly achieving precise proportional control of fuel injection and mixing with the intake air, and eliminating the shortcomings of external cylinder injection. At the same time, special designs such as nozzle position, spray shape, intake air flow control, and piston top shape enable the fuel and air to fully and evenly mix throughout the cylinder, thereby ensuring complete fuel combustion and higher energy conversion efficiency.
