What is the difference between engine T and TD?

[ArianaMarie]

Here is the introduction to the difference between engine T and TD: 1. T engine: The full English name of the common T engine is Turbo-Boost, which means turbocharging. Its main function is to increase the horsepower output of the internal combustion engine. It can significantly improve the power and torque of the engine without increasing the engine displacement. After installing a turbocharger, the maximum power output of an engine can increase by about 40% or more compared to an engine without a turbocharger. 2. TD engine: The full English name of TD is Direct-injection, which is direct injection technology. It allows fuel to be directly injected into the cylinder through the nozzle. This technology can further improve the thermal efficiency of gasoline engines and reduce emissions. The TD behind the engine represents the combination of turbocharging and direct injection technology. Different turbocharged direct injection technologies may have different corresponding names.
