50% Efficiency Boost From New Fuel Injection System

chudnall notes a Technology Review story on a new gas engine injection system that promises increased efficiency of up to 50%. "The key is heating and pressurizing gasoline before injecting it into the combustion chamber, says Mike Rocke, Transonic's vice president of business development. This puts it into a supercritical state that allows for very fast and clean combustion, which in turn decreases the amount of fuel needed to propel a vehicle. The company also treats the gasoline with a catalyst that 'activates' it, partially oxidizing it to enhance combustion."

I'm sceptical of anything which proposes to simply double the amount of energy extracted...

They claimed 50% increase of efficiency.

...the alternative would be that conventional engines were spewing out half the gas unburned. Which just isn't the case.

The efficiency of combustion engines are ~20% so you could say that more than half is lost (80% actually). An increase with 50% would but it in the 30% range which seems reasonable to me.
