A famous mechanic named Smokey Yunick made a similer device for car engines years ago but unfortunately patent and law suits killed it.Glad to see folks making use of these kind of efficient technologies. This is the kind of green shit I can get behind any day.

In europe Citroen Peugeot have been fitting particle filters for 10 years, they also carry some nasty fluid to burn it up every so often, mercedes use urea in their blue tec engines, (is that taking the piss?) I have read that introducing small amounts of butane into a diesel improves everything. Technology is good but misdirected into reducing CO2 and real benifits are a side effect. The cat is bullshit, introduced to limit CO and unburnt hydrocarbons, both of which are minimised by the ecu’s these days so they have to make the motor run badly to get the cat to work. Like the climate sciences the science it perverted by politics and money.
