Abstract
An engine includes a fuel injector support element to support a fuel injector and define a first opening through which the fuel injector can inject fuel. A first piston defines a substantially cylindrical inner chamber and a portal into the substantially cylindrical inner chamber. One or more second pistons are arranged to reciprocate inside the substantially cylindrical inner chamber and to define, in cooperation with the substantially cylindrical inner chamber, a combustion chamber. The first fuel injector support element and the first piston are arranged such that, during engine operation, the first piston reciprocates relative to the first fuel injector support element to thereby cause the first opening and the first portal to move in and out of alignment with one another.
