Re-condensing power cycle for fluid regasification
To produce power using the cold in a stored fluid in a cold condensed state (for example, LNG or liquid air), the fluid is initially pumped, heated, and expanded to generate a first amount of power and form initially expanded fluid, which is then re-condensed, re-pumped, re-heated, and re-expanded to generate a second amount of power, where the initially expanded fluid is re-condensed against the pumped fluid from the initial pumping. The technique can be used to store excess energy in the cold condensed fluid using excess energy generation capacity for subsequent recovery when energy is either deficient or otherwise more expense to generate. |

Misfire determination apparatus and method for internal combustion engine
A CPU determines that misfires are occurring in a cylinder subject to determination of whether misfires are occurring when a value obtained by subtracting a rotation fluctuation amount ΔT30[n−2] from a rotation fluctuation amount ΔT30[n] is greater than or equal to a determination threshold. The rotation fluctuation amount ΔT30[n] is subject to the misfire determination. The rotation fluctuation amount ΔT30[n−2] is 360° CA earlier than the rotation fluctuation amount ΔT30[n]. When stopping fuel supply to a cylinder #1 and determining whether misfires are occurring in cylinder #4, the CPU determines whether misfires are occurring after executing a correcting process that corrects the determination threshold to a second determination threshold Δth2, which is less than a first determination threshold Δth1. |
