What does Audi tfsi mean?

Questioner: Zhong Qiang's best answer TFSI is that Audi's patented technology refers to "in-cylinder injection stratified combustion turbocharged engine". Because stratified combustion technology must rely on in-cylinder direct injection, it can be simply called "stratified combustion turbocharged engine", in which "FSI" refers to stratified in-cylinder direct injection fuel, that is, in-cylinder direct injection and stratified combustion technology. Audi's TFSI is based on FSI, adding T, that is, turbocharging technology. However, because the quality of domestic fuel can not meet the requirements of stratified combustion, the domestic FSI model cancels the stratified combustion technology and only retains the direct injection in the cylinder. I hope it helps you.
