Why cant someone come up with a device which can be fitted to the silencer of cars to cut out harmful emmision

Question

The device can be manufactured with existing cars and laws can be set to make it compulsory in every vehicle. It can be low cost too.

Answer 1

Because the emissions from cars that are hazardous are in the form of a gas, not a solid particulate. That being siad, a filter would be useless as the gasses would still pass through it. Containment would not help either as you'd be left with 1 of 2 options. 1: Empty the container when it's full thus defeating the purpose of containing it in the first place or 2: Dispose of the container that trapped the gas which would rapidly overflow our land fills causing an even greater hazard. The solution is not in trying to cut the emissions in an internal combustion engine, (The types that use gasoline as fuel) but in re-inventing the engine itself so that it will burn a fuel that has no harmful emissions at all. There are such engines out there now however the cost of them at this time is far to great for most people to afford.

Answer 2

Its called a tune up. my 1964 El Camino is tuned well enough that it meets 1998 California emessions without even a catiletic convertor. And gets 34-38 mpg on the hi-way

Answer 3

They did... in the mid 70"s ... But is wasn"t a total success...
It had many problems a a cost of over 800 dollars...

The best would be to be able to convert all cars to electrical power... no gaz...., but oil companies will do everything not to have the electrical car on the market... But it has started now in California.....

Also, I agree with you.... In fact, many of the cancers they accuse cigarettes of are actually caused by car gaz, but who would tell the truth when everyone wants to keep their cars....
including doctors...

Answer 4

Such a device exists and is called catalytic convertor. In some big cities in India it is compulsory to have catalytic convertors installed in your cars.

Answer 5

Um, because it would be logical. Hello?
