Innovation with Automobiles, Cars: Fuel exhaust collector in-built

I thought of this idea of fuel exhaust collector when there was a lot of hue and cry in New Delhi to ban the Diesel Cars as they were found to be more polluting because of their exhaust content than their Petrol counterparts. Ideas presented may be weird but should not be impossible.

I think the problem of pollution by any automobile is a result of oversight at the time of ther initial development. If we compare an automobile with a human being (which is often done by auto fans and designers all the time), it is easy to spot that human beings exhaust (read excrete) only CO2 all the time in atmosphere and other stuff in confined and well regulated manners (read POTs). However automobiles manufacturers seems to have hardly explored this exhaust system in all its efficacy and therefore they allow the vehicles to defecate (read eminate exhaust fumes) all the time while they run. This was acceptable as long as atmosphere was pristine and there were a few vehicles on the road and their exhaust fumes hardly impacted atmosphere whichwas till the beginning of 20th century but not any more.

Therefore here's my suggestion. Do let me know your thoughts on the same. I promise to reply back.

We know that exhaust fumes of a car add to air pollution because of suspended particulates and gases being a part of it. Now, cars companies slog hard to work out the best fuel efficiency and reducing emissions and even designing hybrids which is a major innovation of the auto industry. But I wonder if they have ever thought about collecting a portion of these emissions in another filter/bin which can be a part of the automobile itself. What I mean is that once fuel has been made best use of, the particulate matter of the exhaust fumes can be again filtered and collected in a collector (I have seen mufflers of bikes collecting some of it and local mechanics burning the inner silencer time and again but I wonder if that collection is done purposefully and whether it is enough). These collectors can then be emptied at the time of servicing of these automobiles oror at smaller intervals at fuel stations which they anyway visit so often.

This waste collection has to be taken up by Municipal bodies and ways need to be thought of of maing best use of it and/orbes way of disposing it finally in a safer place to minimise its impact on human lives. If this can be done then a lot of harmful particulate matter can be saved from mixing in environment "red-hot" and we might have cleaner air to breathe.

Do tell me what do you think of it! CYA
