Abstract
Highly efficient engine. The system includes an internal combustion engine having at least one piston in a cylinder, the cylinder including a cylinder head. The engine operates on an unsymmetrical expansion and compression cycle wherein the expansion portion of the cycle is greater than the compression portion of the cycle. The piston and cylinder head are lined with an insulating material having a selected thermal diffusivity. Apparatus is provided for injecting a supercritical mixture of fuel and water into the cylinder of the engine. The combination of these aspects results in a highly efficient engine.
Claims15
Engine system comprising:
- an internal combustion engine having at least one piston in a cylinder, the cylinder including a cylinder head;
