Abstract
A piston system for a compression engine that detonates fuel during an appropriate part of the cycle includes a main piston and an inner piston that is within the main piston, and the head of the inner piston is preferably substantially smaller than the head of the main piston. In operation, the inner piston's path through the cylinder is offset by a predetermined amount with respect to the main piston's path through the cylinder such that at the point when the main piston is just past the zenith, the head of the inner piston becomes flush with the head of the main piston. This motion of the inner piston ensures that fuel will detonate when the main piston is just path the zenith, avoiding damage from untimely detonations. The ratio of the area of the main piston to the inner piston determines the timing of the detonation.
