(redirected from Turbo (cars)) Also found in: Dictionary.
a centrifugal compressor which boosts the intake pressure of an internal-combustion engine, driven by an exhaust-gas turbine fitted to the engine's exhaust manifold
An exhaust-gas-driven air compressor used to increase the power of a reciprocating engine. The exhaust gases drive a small radial-in-flow turbine to drive a centrifugal-type air compressor which, in turn, sends the compressed air into the cylinders. It is located between the air intake and the carburetor. Also called an exhaust-driven turbocharger.
