The engine uses pneumatic actuators rather than a cam to open and close the valves in the engine. The engineers behind this claim that it can provide "30 percent more power and torque, and up to 50 percent better economy" when applied to an existing engine designs. The article and some of the comments also mention that some work has been done with electromagnetic actuators to accomplish the same task. It may be a while before this tech is mature enough for passenger vehicles, but maybe if a racing series or two picked it up, it might give some of the manufacturers the opportunity to work the bugs out?

Not sure this is on topic for SoylentNews, but the article brought me back to my introduction to engineering course in college. One of my classmates was a car nut and I remember a discussion with an EE professor one day about the potential (or actually lack thereof due to performance issues) for using electric actuators to open and close valves."

    If all the pollution is in one location, you can more easily and efficiently filter it. You can also more easily pick where the population occurs. City smog and air quality would become and issue of the past.

    City smog and air quality are negligible compared to climate change. And no, you can't filter out the CO2.

      CO2 is not the only exhaust that comes from burning fossil fuels. It just happens to be the only one that anyone seems to ever talk about.

    True, but from what I've read, intensive lobbying by the power industry has resulted in a weakening or delay of those stack scrubbing requirements.
