Abstract
Methods and systems for cooling a radial engine in a ground-based portable electric power generating system. The engine includes a plurality of cylinders extending radially from a central hub supporting a crankshaft. Each cylinder has a coolant inlet port and a coolant outlet port. The cooling system includes an inlet coolant manifold interconnecting at least two of the coolant inlet ports. The inlet coolant manifold is disposed external to the central hub.
Claims8
A ground-based electric power generating system, comprising:
- a generator coupled to a radial engine of the type including a central hub and a plurality of radially extending cylinder assemblies, each cylinder assembly comprising:
- an inner sleeve having a top flange, wherein the inner sleeve is configured to provide a path for a reciprocating piston;
- an outer jacket having a cylindrical jacket wall terminating at a horizontal step, a fluid inlet port extending through the cylindrical jacket wall, and a fluid outlet port extending through the cylindrical jacket wall;
- a fluid path defined between the inner sleeve and the cylindrical jacket wall of the outer jacket;
- and
- a cylinder head having a horizontal plate;
- wherein the top flange is clamped between the horizontal step and the horizontal plate to thereby secure the inner sleeve within the cylinder assembly;
- wherein the fluid inlet port is configured to communicate cooling fluid to the fluid path from a fluid inlet manifold disposed external to the cylinder assemblies;
- wherein the fluid outlet port is configured to communicate cooling fluid from the fluid path to a fluid outlet manifold disposed external to the cylinder assemblies;
- wherein the fluid inlet manifold is a regular, nine-sided polygonal structure having rotational symmetry about an axis defined by a crankshaft of the radial engine wherein each vertex of the polygonal structure is coupled to a corresponding inlet port of the cylinder assemblies.
