Audi engines are known for their high performance, cutting-edge technology, and exceptional engineering. If you're wondering how to say "Audi engine" in English, it's simply referred to as an "Audi engine." However, if you want to be more specific about the type or model of Audi engine, there are several terms and acronyms you should know.
Types of Audi Engines
1、TFSI (Turbo Fuel Stratified Injection): This is an advanced form of a turbocharged gasoline (petrol) engine that features fuel stratification and direct injection. The term "TFSI" stands for Turbo Fuel Stratified Injection.
2、FSI (Fuel Stratified Injection): This type of engine uses fuel stratification and direct injection but without forced induction (turbocharging or supercharging).
3、TDI (Turbo Direct Injection): These engines feature turbocharging and direct fuel injection but do not use fuel stratification.
4、TSI (Turbo Stratified Injection): These engines combine turbocharging with stratified fuel injection.
5、TDV (Turbo Diesel Vantage): A type of diesel engine that uses turbocharging and direct fuel injection.
Key Technologies in Audi Engines
1、EA888: This is one of Audi's most popular engine families. The EA part stands for "Entwicklungsauftrag" in German, meaning "development assignment," and the number indicates the order of development. The EA888 series includes various iterations such as Gen3 BZ and Gen3, which incorporate technologies like hybrid injection (PFI + GDI) and variable cam lift (AVS).
2、AVS System: Audi Valvelift System allows for variable control of valve lift and timing. It enhances both performance and fuel efficiency by adjusting the actuation of the intake and/or exhaust valves depending on the driving conditions.
3、Budack Cycle: Named after its developer, Dr. Robert Budack, this cycle optimizes the expansion and compression phases in the engine's four-stroke process, improving thermal efficiency.
4、Hybrid Injection: Some modern Audi engines feature a combination of port fuel injection (PFI) and direct gasoline injection (GDI). This system improves combustion efficiency and reduces carbon build-up on the intake valves.
Specific Engine Models
EA113: A classic inline-four engine that was produced by Audi from 1974 to 1994.
EA837: Known for its 2.5-liter inline-five configuration used in the Audi Coupe.
EA839: A 4.0-liter V8 engine used primarily in higher-end Audi models.
Conclusion
Understanding the different types and technologies behind Audi engines can greatly enhance your appreciation for these sophisticated powerplants. Whether you own an Audi vehicle or are simply an automotive enthusiast, knowing these terms will help you communicate more effectively about Audi engines. So, the next time someone asks you what an Audi engine is called in English, you can confidently say "Audi engine" and elaborate with technical details if needed!
