Sep 05: The patent war of Digital Twin Spark Plug ignition, DTSi technology between TVS and Bajaj is taking several twists as TVS has claimed that Twin Spark technology has been already patented by Honda Motor Company of United States, while Bullet making company Royal Enfield has also claimed to using similar technology to DTSi in its new model that is going to enter in the market by the end of the year.
From the confirmed sources, Lakshmi Kumaran, has told that DTSi technology had been already patented in the US by Honda Motors Company. So, “We have contended that the grant of patent to Bajaj is wrong", said Kumaran, TVS patent attorney.
While on the other hand Royal Enfield, the maker of the Bullet brand of lifestyle bikes, has claimed to use similar technology to Twin Spark Plug, but also said that their technology is something different as Royal Enfield uses valves while Bajaj Auto and TVS Motors primarily use overhead cams in their engines. “The twin spark plug technology is already in use for many decades and we have used it in our engine architecture to make it more efficient and make combustion easier”, said R L Ravichandran, CEO of Royal Enfield. Royal Enfield is developing a new twin spark engine for its 350cc engine for its new Thunderbird model that is expected to come in the market by the end of the year.
On the other hand Bajaj has accused TVS to use the DTSi technology for ‘Flame’ model of TVS that is going to launch in the coming November. Flame has 125 cc of engine having Controlled Combustion Variable Intelligent, CC-VTi technology on which Bajaj has objected to.
Earlier Bajaj has asked TVS to not to use DTSi technology as Bajaj has the only authority to use it. But TVS has refused to accept it by quoting, “why petition was filed just days before when TVS is going to unveil its new 125 cc bike Flame”. In the reply Bajaj has threatened to file suit against TVS of worth Rs. 250 crore for infringing the patent of Bajaj.
DTSi technology is an advance technology in which two spark plugs has been used in stead of one spark plug per engine cylinder.
