Engine Tuning

Engine tuning refers to the process of adjusting and modifying an internal combustion engine, and any modification done to the control-unit, which is otherwise called Engine Control Unit (ECU). This procedure is performed in order to generate optimal performance or improve on power output, durability, and economy of an engine.

These goals do not have to be mutually co-dependent, but an engine could get detuned in terms of output. Longer engine life or better economy then results from this detuning action since stress gets lessened on engine components.

Setting the fuel/air mixture, idle speed, carburetor balance, distributor, and spark-plug point gaps, and ignition timing were observed as routine tuning aspects for old engine types. They also marked the final, yet essential steps to setting up racing engines. For modern engines, however, which are equipped with fuel injection and electronic ignition, a part of these tasks, or all of them are automated, even though they still demand periodic calibration.

Engine tuning incorporates regular servicing that targets specifications set forth by a given manufacturer.

Engine tuning incorporates regular servicing that targets specifications set forth by a given manufacturer. It requires being done periodically as per recommendations made by the manufacturer which ensures that automobiles run as expected. Present-day motor vehicles typically require only a minor number of engine tuning exercises all through the course of approximately 250,000 km, which is equivalent to lifespan of 10 years.

Different forms of engine tuning exist including refastening done on cylinder head-bolts, adjustment of carburetor idle speed, as well as air-fuel mixture. Components of the ignition system such as contact breaker points, spark plugs, and the distributor rotor may be inspected and replaced if necessary. Engine tuning also involve replacing filters of air, inspecting emission controls, and adjusting the valve-train.

Contemporary engines come fitted with Engine Control Unit (ECU), or Engine management system (EMS). Engine tuning may be done on these leading to differential settings, which then produces varying levels of performance. Oftentimes, manufacturers produce few engines that may be used within other contexts. Such action permits manufacturers to sell motor vehicles in numerous markets. This excludes necessity of expending cash for designing and developing multiple engine-types that confer to the rules set. Engine tuning also permits the use of single engines by varied motor vehicle brands, attuned to specific buyer markets.
