What is the engine model of the Audi A8?
1 Answers
Audi A8 offers four displacement options, equipped with a 2.5L V6 FSI direct injection engine, a 3.0L V6 TFSI supercharged direct injection engine, a V-8 cylinder 4.0L V8 TFSI turbocharged direct injection engine, and a 6.3L W12 FSI engine. FSI engine: The FSI engine stands for Fuel Stratified Injection, which is a technology based on GDI (Gasoline Direct Injection). Compared to conventional port fuel injection engines, the FSI engine directly injects fuel into the combustion chamber. Due to the vaporization effect of the spray, it optimizes the air charging efficiency. By achieving quality regulation of the gasoline engine, the throttle is no longer needed, significantly reducing intake losses. Stratified combustion reduces the engine's heat transfer losses, thereby increasing full-load output power and reducing fuel consumption under partial loads. TFSI engine: The TFSI engine is short for Turbocharged Fuel Stratified Injection engine, which can be considered a combination of the FSI engine and a turbocharger, i.e., Turbocharger + FSI.
