Abstract

Spark Ignition Engine is widely to power motorcycles. Single spark plug is used\nin igniting the air-fuel mixture is not so efficient during high speed and heavy loading\ncondition. Moreover, the process of burning of the fuel is also not always instantaneous.\nHowever, an alternate solution to it is by making the combustion of fuel as fast as possible.\nThis problem was resolved by introducing the revolutionary twin spark ignition system. By\nusing two spark plugs which spark alternatively at a certain time interval, the diameter of\nthe flame and instantaneous burning of the fuel increased. This system is called DTS-i (Digital\nTwin Spark Ignition system). Due to DTS-i system it was possible to combine strong\nperformance and fuel efficiency. The improved engine efficiency modes have also resulted in\nlowered fuel consumption. The efficiency of the small displacement engines was enhanced\nwith increased power output just by increasing the number of fuel igniting element i.e.\nSpark Plug. Thus a good design and control of the system parameters becomes most\nessential for optimum performance of an engine. DTS-i offers many advantages over\nconventional mechanical spark ignition system. This paper reviews the eminent work and\nresearches done for enhancing the performance of Twin Spark Ignition System.\nResearchers have studied and developed the DTS-i engine on various parameters such as\nspecific fuel consumption, thermal efficiency, exhaust gas emission and engine performance.\nAlthough this technological trend proved to be sufficient, a new well-improvised ignition\nsystem was given birth and named as “Triple Spark Technology” involving the use of three\nspark plugs rather than one or two. This paper also reviews the use of DTS-i with different\nfuel feeding system.
