Gizmag has a very interesting piece about a new fuel injection system mod that has been developed at the University of Wisconsin, that promises to offer a thermal efficiency of 53%: http://www.gizmag.com/diesel-spark-plug-gasoline/12484/?utm_source=Gizmag+Subscribers&utm_campaign=9224d606ed-UA-2235360-4&utm_medium=email This is an amazing gain as the article explains and the US Department of Transportation is offering to fund further research into this promising area in a big way.
I would hope that someone at tata is watching - as the biggest manufacturers of diesel trucks in India and a company who export their trucks and cars to many other countries, they would be a fantastic fit to this technology. The technology has been tested on caterpillar diesel engines - don't Tata have the Indian representation for Caterpillar and Poclain? Someone please correct me if I am wrong here!
In any case, this blog aims to watch this development and look at where it is implemented. If the Tatas don't care for it, maybe someone else could license it in India. I am not sure if Mahindra would - they have a long relationship with AVL. Please watch this space. I shall post any information that I get over here.
