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 10000-kilometre (6200 mi) or a 1-year lifespan.

Tune-ups may include the following:

 

  • 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

 

"Tuning for better MPG." Tuning for economy. With the rising price of fuel one question At Al-Rafay  frequently gets asked is how can a car be tuned for maximum economy. 

First off you need to see if your car is operating within normal parameters. So get your makers stats out and work out if you are getting the right fuel consumption to start with. (Your driving habits and use of air conditioning may also be partly to blame so take the diving boot of the right foot and affix a helium balloon.) Baseline factors for consideration. First off we need to rid ourselves of problem areas that can rob us of fuel economy. You need a good strong spark to ensure that the engine burns the fuel effectively. Clean plugs are an essential so regularly ensure that any glazing is removed from the electrode tips, all leads and hi-tension electrics need to be in perfect working order. The fuel system also needs to be in tip top condition. Over time, on injection engines, the injectors - the little nozzles that spray the fuel into the engine become silted up. Instead of spraying a fine mist of fuel into the combustion chamber, which would burn very well, it squirts a jet of fuel which sits in the bottom of the cylinder and much fuel is wasted. The addition of an injector/carb cleaner and use of high quality fuel will help with this problem but on an older car it is worth considering fitting new injectors. A simple compression test will reveal much about the condition of the engine and it efficiency. An engine which loses combustion pressure will not be efficient. The cost of the work to correct the faults outlined above may well be more than covered by the fuel savings over the next year or so.-- Read more at: https://www.alrafyauto.com
