Piston and bowl for gasoline direct injection compression ignition (GDCI)

A piston for use in a GDCI engine cooperates with the wall of a cylinder defined in the engine and with a cylinder head to define a combustion chamber. The surface of the piston that faces the cylinder head defines a bowl that is configured to receive fuel that is dispensed from a fuel injector that is located in the cylinder head substantially along the central axis of the cylinder. The bowl is configured such that substantially all of the injected fuel associated with a combustion event reaches a localized equivalence ratio greater than 0.0 and less than or equal to 1.2 at a time immediately preceding initiation of the combustion event.

Compressed gas energy storage

Methods and systems for thermal energy storage and enhanced oil recovery are described herein. In some embodiments, natural gas may be injected down a well which has been previously hydraulically fractured to store thermal energy and to stimulate the well to greater hydrocarbon production.
