re dirty diesels nataraja rtsg mot com writes i heard the diesels are considered cleaner burning than gas engines because the emit less of carbon monoxide hydrocarbons and oxides of nitrogen co hc nox but they can put out a lot of particulate matter i heard something about legislation being discussed to clean up diesel emissions is there anything in the works to install scrubbers for diesels how about the feasibility of installing them on trucks and cars would it be any different than a catylitic converter i d assume easier since we re removing particulate matter instead of converting gasses let s hear people s opinions vw and mercedes have tinkered with particulate traps also vw uses a kind of turbocharger on their jetta ecodiesel that helps reduce particulates as well although i don t know the mechanics of it many diesel cars busses and trucks in europe are now being equipped with catalysts and traps in an effort to clean up diesel emissions already well below legal limits anyway it s a shame gm had to soil the diesel s reputation in passenger cars and prevent further resource devotion to research into making this outstandingly efficient engine even further ahead of gas engines in emissions erik
