no it is % by volume...
14.7 :1 is ratio means 1litre of petrol= 14.7 litre of air

If we do comparison of emission norms and emission factor...
Which one is greater? And why?
As per me.. emission factor must be more than norms... but I did comparison... and see the results are emission norms are greater than standards..
