Engine Control Modules & Units (ECM)/(PCM)/(ECU)
The modern internal combustion engine is quite a conglomeration of advanced parts that make it the choice form of transportation. Cars manufacturers continue to build cars with internal combustion engines because they are proven technology and versatile besides. Engines have come a long way since their inception. These days they run on several systems of electronic controls and computers. These newer developments in engine control have made some of the most efficient and powerful engines ever known. Engine control modules are like the central processing and control center for an engine. They help the engine to run at its best. Timing is a major component of the well run engine. Numerous sensor send information to the engine control module. The engine control uses this information to harmonize the workings of the engine so that they achieve optimal performance. They also are much more efficient so that gas mileage is better and emissions cleaner.
