A system and method are used to assess future possibilities of downtime due to a mismatch between a demand of loads requiring electrical power and power resources capabilities to provide such power. Accordingly, a periodic determination of the capacity available by the power resources, the demand of the loads, as well as the current and predicted environmental conditions are performed. Based on the evaluation a future prediction of downtime, i.e., lack of sufficient power supply versus demand is determined. An alert is generated as to the nature and reason of such mismatch. In an embodiment, suggestions as to ways to mitigate such mismatch are also provided.

A piston rod portion may be connected to the piston and extend from a location within the combustion chamber to an area external to the cylinder. A recess in the piston rod portion may form a passageway to continuously communicate gas flow between the combustion chamber and the area external to the cylinder when the piston is in the momentum stroke portion.
A linear reciprocating engine may include a cylinder having a first combustion chamber at one end and a second combustion chamber at an opposing end, first and second cylinder heads located at an end of the first and second combustion chambers, respectively, and a double-faced piston slidably mounted within the cylinder. The engine may further include a first piston rod portion extending from a first face of the double-faced piston through the first combustion chamber, and a second piston rod portion extending from a second face of the piston through the second combustion chamber. Passageways in the piston rod portions may be configured to communicate gases between the combustion chamber and a location outside the cylinder and configured to prevent gases from being exchanged between the cylinder and a location outside the cylinder via a path that crosses both face of the piston.
An internal combustion engine may include an engine block, a cylinder within the engine block, and a piston within the cylinder. The piston may have an outer peripheral wall, and a groove in the outer peripheral wall of the piston may have a first edge and a second edge spaced from the first edge. The piston may have a piston ring in the groove, and the piston ring may have a shape that meanders within the groove, such that the shape of the piston ring differs from a shape of the groove and such that the piston ring does not substantially fill the groove. The piston ring may be constructed of a material that when subjected to heat causes a shape of the meanderings to change, thereby enabling the piston ring to expand in an axial direction of the piston, between the edges of the groove.
An engine may be configured to have a piston reciprocate in a cylinder in which blow-by gases pass from a combustion chamber in the cylinder to an area external to the cylinder. The piston may be connected to a rod configured to reciprocate in a linear path. The engine may comprise a gas exchange chamber configured to trap the blow-by gases in a space between the cylinder and a chamber housing an actuator connected to an end of the rod.

An engine may have a piston linearly reciprocating along an axis in an adjustable cylinder. There may be a piston rod connected to the piston, the piston rod also linearly reciprocating along the axis. A first chamber that includes a combustion chamber in the cylinder may be separated from a second chamber that includes an air chamber. The air chamber may be between the first chamber and a third chamber configured to accommodate lubricant. The engine may be configured to prevent blowby gases escaping from the first chamber into the second chamber from entering the third chamber, and recirculate blowby gases into the first chamber. A passageway may be configured to bring the first and second chambers into communication. The cylinder may be adjustable to change a compression ratio of the combustion chamber. The third chamber may include a mechanism to convert linear motion to another form.

An internal combustion engine for providing a linear reciprocating movement of an output shaft along a longitudinal axis. The engine has a double sided cylinder that is bounded by an engine head at each side of the cylinder. An exhaust unit is positioned at each side of the cylinder. A piston is positioned within a cylinder inner space and freely slides with respect to the cylinder along the longitudinal axis. Two piston rods are aligned with the longitudinal axis. Each piston rod is connected at a different side of the piston. Each of the piston rods has exhaust openings.
An internal combustion engine may include an engine block, a cylinder defining a combustion chamber, and a piston in the cylinder, The piston may travel in a first stroke from one end to an opposite end of the cylinder, and may be sized relative to the cylinder to enable an expansion stroke portion of the first stroke while the piston travels under gas expansion pressure, and a momentum stroke portion of the first stroke for the remainder of the first stroke following the expansion stroke portion. A piston rod portion may be connected to the piston and extend from a location within the combustion chamber to an area external to the cylinder, A recess in the piston rod portion may form a passageway to continuously communicate gas flow between the combustion chamber and the area external to the cylinder when the piston is in the momentum stroke portion.
