Abstract

The invention relates to an ambient temperature thermal energy cryogenic engine with constant pressure with continuous ''cold'' combustion at constant pressure and with an active chamber operating with a cryogenic fluid (A2) stored in its liquid phase, and used as a work gas in its gaseous phase and operating in a closed cycle with return to its liquid phase. The initially liquid cryogenic fluid is vaporized in the gaseous phase at very low temperatures and supplies the inlet (A4) of a gas compression device (B), which then discharges this compressed work gas, still at low temperature, and through a heat exchanger with the ambient temperature (C), into a work tank or external expansion chamber (19) fitted or not fitted with a heating device, where its temperature and its volume will considerably increase in order to then be preferably let into a relief device (D) providing work and for example comprising an active chamber according to international patent application WO 2005 / 049968. Application to land vehicles, motor vehicles, buses, motorcycles, boats, aircraft, standby generators, cogeneration sets, stationary engines.

Description

technical field

[0001] This invention relates to engines.

[0002] More particularly, the present invention relates to engines, operating especially with cryogenic fluids, using means for controlling the stroke of the pistons to have the effect of stopping the pistons at their top dead center for a period of time and spinning the engine, which engines also use A variable volume active chamber that does work, an integrated (or separate) compression device, and a device for recovering heat energy at ambient temperature. Background technique

[0003] The inventors have filed numerous patents and patent applications concerning drives and their devices, using gases, especially compressed air, for completely clean operation in urban and suburban areas:

[0004] WO 96 / 27737-WO 97 / 00655-WO 97 / 39232-WO 97 / 48884-
