Compression ignition Gas Engine

clicky

Just read an article in the March 14' Car and driver about huyndai's experimental "gasiel" engine. Interesting read although the link is to a different article on the same engine.

Thoughts???

LOL,

Nayan Engineer (yes, that’s really his last name), a powertrain engineer with Hyundai.

Nayan Engineer, engine engineer.

The idea is not new. It requires heavier components, as a diesel does. Injection pressure needs not be as high because the fuel is not as viscous.
Temps will be higher than diesel requiring better alloys in pistons etc or stainless capped pistons etc.
Operating ranges will be narrower as a diesel usually is, imo. They can engineer high performance versions but they will be heavier still.
The idea of the design is not performance but economy, of fuel consumption only. Cost, of everything, including fuel, including taxes will be much higher.

Well, I know of diesels that used a gasoline system for pre-heat, Those have indeed been out for a long time,, Drove one myself over 40 years ago for a bit (It was a skip loader).

Always wondered why that technology wasn't considered for civilian use. The US military had been using multi-fuel compression ignition engines for over 50 years.

If they can engineer something innovative, more power to them. This type of engine will work very well with turbos.

I'd like to see an engine go the next step and be able to run on either gasoline or diesel with the ECM doing all the work in getting the right mixture into the combustion chambers.
