World’s cleanest internal combustion engines?
 
PSA Peugeot Citroën has sold more than 3 million HDi diesel engines fitted with a Diesel Particulate Filter

Hi,

I think that this engine design has a legitimate shot at being the cleanest, simply by virtue of it's superior efficiency: 39.5%

The most efficient ICEs today are very, very large engines, such as this 25000 liter two-stroke turbo diesel ship engine with ~50% thermal efficiency. I would guess that large, stationary diesel generators are also efficient, since weight isn't much of a concern and they can add waste heat recovery systems, etc.

Or if by "cleanest", you mean you'd survive the longest while locked in a garage with one running, I'd go for the Honda 1.0L 3cyl that came in the Insight with CVT. I don't know of a car with lower NOx, CO, and HC emissions.

Huh ? That slipped past me. What is 'froggy' crap ?

I saw a show a few days ago about trains.
I was surprised to see that miners use small underground trains that run on diesel.
The engines have a particulate filter that filters the exaust so well that there are practically no emissions at all.
At first, I wondered how this would work on a street car, but then realized that the fuel economy and acceleration would be horrendous.
It looks like it is possible in the article above though.
It's good to see someone sucessfully using the filters on cars.

Citroens are French cars, and "frogs" is a derogatory term for the French.
