What does TDI stand for?

[CarsonLynn]

TDI stands for Turbocharged Direct Injection. Many turbocharged engines and naturally aspirated engines are equipped with direct injection technology. In engines with direct injection technology, the fuel injector is located inside the cylinder. This injection method allows for more thorough atomization of gasoline, ensuring better mixing with air. However, most direct injection engines have a drawback: they are prone to carbon buildup, especially on the valves and in the combustion chamber. Therefore, it is recommended that owners of vehicles with direct injection engines regularly clean the carbon deposits inside the engine. For carbon removal, the walnut shell blasting method is suggested, as it is quite effective.
