Well, then I ask once again to think sensibly!
What is the treaty that Pak has signed regarding pollution control? To make vehicles upto Euro 3 standards? Do you think so? Name even one locally assembled Petrol car which is even Euro 2 compliant in the form it is sold in!
An therefore I repeat, 2c can be upgraded to comply with Euro 2, (as most of the petrol cars can be too), but that requires new diesel fuel! Without that, nothing can be done!
So the point is that a new motor will be good, no question, but would NOT reduce the pollution!
And I sense that they are really (after all these long years) going to reduce the diesel sulphur content, but sadly because India has already done so! with the mentality whatever India does, we have to do the same!
