TVS’ RANGE TOPPER LAUNCHING SOON
APACHE RTR 160 4V
Having developed parts for racing motorbikes and competed in the Dakar Rally, TVS, to date, has the distinction of developing plenty of firsts for the Indian motorbike industry and is known for their technical innovation and expertise. TVS Auto Bangladesh Limited is all set to introduce the brand new TVS Apache RTR 4V in the country, with an exciting spec sheet that promises quite a bit. The 160cc segment has a number of significant competitors, but the RTR 160 4V looks sharp, has the goods and has the performance to match. There’s no doubt about TVS’ engineering ability, but what are the facts?
Bangladeshi engineer-led team develops “cool burn” combustion tech at University of South Carolina
INTER VIEWED BY ROBIN GAZI
Tanvir Farouk graduated from BUET in 2002, and then went on to earn a Ph.D. from Drexel University. Currently he’s an Assistant Professor at University of South Carolina. His research work is focused on high-efficiency combustion, emission control, non-thermal plasma-based energy systems and reacting flow in general.
How does the engine work?
I would like to clarify that we have not developed an engine but a combustion methodology. Our experiments have shown that “Cool Flame combustion can be attained for diesel-like fuels. In the “Cool Flame” burning mode the temperature is typically In the 700 – 800 K range and no visible flame is observed, rather the fuel-oxidizer mixture undergoes a homogeneous burn. The dynamics of the flame evolution and vaporization of the liquid spray allows a self-sustaining Cool Flame” burn to be attained.
What are the advantages of cool burn of diesel?
It greatly reduces heat loss and emissions in diesel engines.
How efficient is such an engine compared to traditional diesel engines?
In comparison to a gasoline engine which has an efficiency of 35% a conventional diesel engine has an efficiency of 45%. An engine employing “cool burn” enables it to achieve about 65% efficiency.
When do you think this technology would be ready for commercial use?
We are currently working with one of our collaborators to conduct and analyze a series of engines tests. I cannot provide a definite timeline for commercial use at the moment.
Why do you think cool burn of diesel is relevant in a world moving towards EVs and fuel cells?
The world is moving towards EV’s and fuel cells vehicles because they scale up perfectly for small, personal vehicles. Long distance freight hauling still depends on diesel or even heavier fuels. As a consequence, the cool burn of diesel will contribute to these sectors by not only providing higher efficiency but also lower emissions.
