An engine (400) is disclosed and comprises: a compressor (428) which periodically defines a chamber and carries out a pressurization process wherein the chamber volume is decreased to produce pressurized air; a combuster (426) which combusts fuel with the pressurized air to produce primary exhaust; an air motor (408) which is driven by the primary exhaust to produce power and secondary exhaust; an expander (410) which expands the secondary exhaust to produce tertiary exhaust and power; and a shaft (314) which directs power produced by the motor (408) and the expander (410) to the compressor (428) and any load. The combuster (426) is adapted to receive varying amounts of fuel, thereby to vary the power to the load. The compressor (428), during pressurization. releases air from the chamber such that the chamber pressure during pressurization and the primary exhaust pressure is substantially constant at steady state conditions, said constant being a function of the load being driven by the power.

One or more component braces may be installed into the upper valley of a V-styled engine block to provide resistance to deformation of the block when used in an operating motor. The component braces include first and second mounting portions separated by a body portion, where the mounting portions may be constructed as arms extending from the body portion. An intermediate mounting portion may also be included that is centrally located with respect to the first and second mounting portions, but below a line defined by the first and second mounting portions. The securing of the component brace at the mounting areas provides rigidity to the upper portion of the engine block to resist deformation, such as would occur as relative movement between the cylinder banks. The resistance to such deformation aids in the prevention of cylinder bore wall distortion as well as engine block cracking.

The present invention is an oil burning system, capable of burning various waste oils with high efficiency burn, reduced emissions, and without producing sludge within the system.
