As every day more fuel is being used by a growing number of vehicles, fuel dependency growth and a growing concern for our environment health, it is a crucial point to gain in fuel efficiency for ground transportation engines. Many approaches are being investigated, but we will focus in one kind that we call the HCTI, homogeneous charge thermal ignition engine. The goal with this new kind of ignition is to increase engine efficiency both by igniting the mixture using a much bigger surface that a spark plug kernel would be, thus lowering pumping losses, and also by burning leaner mixtures that are thermodynamically more efficient with a reticulated ceramic matrix, something that couldn't be possible with SI because such lean mixtures wouldn't burn with a spark plug. In this paper an SI engine will be monitored and also the same version of the HCTI to try to determine if there are gains in efficiency according to the theory.
