This system gives hydro-carbon levels that would meet 1975 kinds of problems. It would give carbon monoxide levels meeting the 1975 requirements. It won't do the job on oxides of nitrogen...
Another approach we can take with essentially the engine we have today is the so-called catalytic approach. And this amounts to putting a catalyst essentially in place of the present muffler. This is usually an oxidizing catalyst because we have to somehow burn up the carbon monoxide, hydro-carbon.... Right now, for example, one of the major problems of lead in gasoline, is coating the catalyst and the catalyst doesn't last very long...
...eliminate lead we more than double spark plug life. When the spark plug misfires, it tremendously increases the amount of hydro-carbons that go out into the atmosphere...
Again, the steam engine does very well on hydro-carbon and carbon monoxide, but will not pass the oxides of nitrogen requirements...
...kind of programs that we have here we think that we are responding to the requirements of the regulatory agencies and the government. Right now we have reduced pollutants 80 per cent from where we have started. What we are working on is the last 20 per cent in hydro-carbons. Now it depends on how much lower that should be at what ultimate price to the consumer...
