Engine Tune-up
A tune-up usually refers to the routine servicing of the engine to meet the manufacturer's specifications. Tune-ups are needed periodically as according to the manufacturer's recommendations to ensure an automobile runs as expected. Modern automobiles now typically require only a small number of tune-ups over the course of an approximate 250,000-kilometre (160,000 mi) or a 10-year lifespan.
Tune-ups may include the following:
- Re-fastening of cylinder head bolts
- Adjustment of the carburetor idle speed and the air-fuel mixture
- Inspection and possible replacement of ignition system components like spark plugs, contact breaker points, distributor cap and distributor rotor
- Replacement of the air filter and other filters
- Inspection of emission controls
- Valvetrain adjustment
In early days, mechanics finished tuning up a performance car such as a Ferrari and would take it around a track several times to burn out any built-up carbon; this is known as an Italian tuneup.

Famous quotes containing the word engine:
“Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
—Aldous Huxley (1894–1963)
