CYLINDER DEACTIVATION ON TWO DIFFERENT CUBIC CAPACITY ENGINE

Cylinder deactivation is a fuel consumption reduction technology for throttled internal combustion engines and other engines with thermal efficiency loss at part cylinder. Dynamic skip firing, which in its ultimate form incorporates anytime, any-cylinder deactivation, continuously varies the number of firing cylinders, along with cylinder load, obtaining flexible control of acoustic and vibrational excitations from the engine, and allowing an expanded operational envelope with fewer drive ability/NVH issues. This project comprises of two different cubic capacity 4 stroke (150cc-pulsar and 100cc-kinetic) engines coupled with use of sprockets and chains. Even though the cylinder deactivation can also be done by cutting down the fuel supply for any one cylinder depending on vehicle speed, still the deactivated cylinder produces frictional power loss. By adopting this method losses can be avoided and the engine will also run at prefect balanced condition. Thus the engine will be operated at its maximum efficiency and reduce the fuel consumption and emission.
