Many people are wondering what tfsi means after Audi. In fact, some cars have signs like 1.4T and 1.8T on the back, but Audi cars do use tfsi. This is related to automobiles. T is a turbocharger, and the fsi behind it involves patented engine technology. Tfsi is a stratified combustion turbocharged engine
what do you mean by tfsi? In fact, he is Turbofsi, which is a turbocharged fsi engine. Everyone should be familiar with it. But at that time, FSI was actually Audi's patented technology, which meant direct fuel injection stratified and stratified combustion, full name in-cylinder injection.
actually, it is a special engine fuel supply technology, that is, the fuel is injected once in the intake stroke, and the mixture formed is so thin that the spark plug cannot be ignited, so the fuel is injected again during compression, and the mixer at this time is rich (12:1) and can be ignited. As long as the purpose of stratified combustion is achieved, the fuel can burn more fully and save energy.
Audi's patent is very advanced, but the quality of domestic fuel can't meet the requirements of stratified combustion, and only in-cylinder direct injection is reserved, which leads to Audi's patent not playing its due role. After all, this technology has greatly improved fuel economy, reduced engine weight, saved fuel and reduced manufacturing costs.
unfortunately, the mechanical supercharging and stratified fuel injection have been cancelled in China, leaving only turbocharging and direct injection in the cylinder, but the effect is still good, but it is not as good as the original tfsi effect. Therefore, the tail of the Audi tfsi is no longer just the original meaning, but also the G value of the acceleration of this car. The larger the value, the faster the acceleration.
