turbocharger
C1Technical, automotive engineering, industrial, informal (metaphorical)
Definition
Meaning
A device that uses a turbine driven by exhaust gases to force more air into the combustion chamber of an internal combustion engine, significantly increasing its power output.
A mechanism for forced induction; metaphorically, any person, process, or technology that dramatically increases efficiency, speed, or performance.
Linguistics
Semantic Notes
Primarily a technical noun; metaphorical use is common in business and tech contexts to denote a performance booster.
Dialectal Variation

Memory Aids
Mnemonic
Think: 'TURBO' (fast spinning) + 'CHARGER' (fills up with power). It's a charger that uses turbo power.
Conceptual Metaphor
A PERFORMANCE BOOSTER IS A TURBOCHARGER (e.g., 'The software update was a turbocharger for the old laptop.')
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Not to be confused with 'турбина' (turbine) alone; a turbocharger is a specific assembly incorporating a turbine and a compressor.
- The metaphorical verb 'to turbocharge' is best translated conceptually as 'резко ускорить/усилить', not literally.
Common Mistakes
- Misspelling as 'turbocherger' or 'turbochargar'.
- Using 'turbo' and 'turbocharger' interchangeably in very formal technical writing (the former is less specific).
- Confusing with 'supercharger' (a different forced induction device mechanically driven by the engine).

FAQ
Frequently Asked Questions
Both are forced induction systems. A turbocharger is powered by exhaust gases, while a supercharger is mechanically driven by the engine's crankshaft (usually via a belt).
Yes, it's commonly used metaphorically in business, technology, and economics to mean 'to make something much more powerful or effective very quickly.'
In informal and enthusiast contexts, yes (e.g., 'a turbo diesel'). In precise engineering writing, 'turbocharger' is preferred for clarity.
A brief delay between pressing the accelerator and the turbocharger delivering increased power, caused by the time needed for the exhaust flow to spool up the turbine.
