Abstract (en)
[origin: WO9532360A1] A process allows waste heat from an internal combustion engine to be recovered. At least part of the thermal energy contained in the exhaust fumes from a first stroke and in the engine block are used to evaporate a liquid injected into the combustion chamber and the exhaust fumes of the preceding stroke before a second stroke begins. The thermal energy is thus used to increase the total pressure of the mixture of exhaust fumes and liquid vapour and is transformed into mechanical work during the following stroke. The disclosed process, illustrated as a six-stroke engine in the figure, enlarges the combustion chamber during the fourth and fifth strokes in order to avoid the very high temperatures and pressures that result from recompression during the fourth stroke, and also converts the residual energy into mechanical work.
