The so-called heat exchanger water out of the present invention can be used as the exhaust outlet of water, also this water out can be communicated with the firing chamber of burst emission engine after the heat exchanger heats vaporization through high-pressure service pump or through high-pressure service pump again.
The so-called liquifier water out of the present invention can be used as the exhaust outlet of water, also this water out can be communicated with the firing chamber of burst emission engine after the heat exchanger heats vaporization through high-pressure service pump or through high-pressure service pump again.
Beneficial effect of the present invention is as follows:
The closed motor of nitrogen liquefied carbon dioxide disclosed in this invention has been realized efficient, the low emission of motor, has improved the feature of environmental protection and the energy saving of motor greatly.
