One of the biggest controversies in recent times in the domestic automobile industry may have come to an end with two-wheeler major Bajaj Auto Ltd getting a patent for its ExhausTEC technology to improve the efficiency of a two-wheeler engine.
ExhausTEC along with Bajaj’s other patent for DTSi technology have been a bone of contention for the Pune-based company with maker TVS Motors.
“The Indian Patent Office granted Bajaj Auto a patent for its ‘ExhausTEC’ invention vide Patent No 231498 dated March 5, 2009. This grant was published in Patent Gazette, dated March 27, 2009,” said S Ravikumar, vice-president (Business Development) Bajaj Auto Ltd (BAL). “With this, we will have the right to seek legal remedy against possible infringements.”
The technology improves low- and mid-range torque in a single cylinder four-stroke engine, employing a chamber of predetermined volume attached to the exhaust pipe. This combined with DTSi delivers unbeatable fuel efficiency and performance combination, Ravikumar said.
Bajaj has been using this technology on its bikes since August 2004.
Bajaj and TVS had clashed on issues related to technology infringement in 2007 when TVS developed the 125cc Flame using a technology similar to Bajaj's. What followed was a protracted battle between the two companies played out both in public as well as in courtrooms.
TVS on its part said the grant of this patent to Bajaj does not impact its products or business in any way. “There is no correlation between DTSi and ExhausTEC technologies and the patents are separate as well,” said Cecil Dewars, vice-president, corporate communication, TVS motors. “These are two independent technologies and are not used by TVS in any of its products.”
