20150322874 | POWER GENERATION SYSTEMS AND METHODS - A number of exemplary power generation systems and methods are disclosed herein. In some embodiments, a compressed air energy storage system, optionally with split-cycle engine technology, is used to store energy obtained from the grid during off-peak hours and to supply stored energy to the grid and/or to an end user during on-peak hours. The system can include heat recovery features and can supply heat to the end user. In some embodiments, a generator system is used to provide power to an end user and to the grid. The generator can be maintained in a high efficiency operating range (e.g., at elevated or full load), even when the generator output exceeds the end user's demand, with any excess generated power being fed to the grid. | 11-12-2015 |
20140158102 | SPLIT-CYCLE AIR-HYBRID ENGINE WITH AIR EXPANDER AND FIRING MODE - A split-cycle air hybrid engine includes a rotatable crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression (XovrC) valve and a crossover expansion (XovrE) valve defining a pressure chamber therebetween. An air reservoir is operatively connected to the crossover passage. An air reservoir valve selectively controls air flow into and out of the air reservoir. In an Air Expander and Firing (AEF) mode of the engine, the engine has a residual expansion ratio at XovrE valve closing of 15.7 to 1 or greater, and more preferably in the range of 15.7 to 1 and 40.8 to 1. | 06-12-2014 |
20130298889 | OUTWARDLY-OPENING VALVE WITH CAST-IN DIFFUSER - Disclosed is an engine valve port including a valve opening, a first portion, and a separate second portion. The first portion and the second portion are separately connected to the valve opening, and the first portion and the second portion merge together at a location spaced from the valve opening. The valve port has a bifurcated, porpoise-like shape. The first portion and the second portion are generally arcuate in shape, and the first portion and the second portion have a generally semicircular cross-section. Also disclosed is an engine including such a valve port. A valve associated with the valve port may be an outwardly-opening valve. | 11-14-2013 |
