Self-cooled engine including a cylinder and cylinder head with a turbo-piston which freely reciprocates inside the cylinder. The cylinder head has a valve that achieves circumferential suction of air-fuel mixture into the cylinder. The valve mechanism is closed and opened by cylindrical cam by means of cam shaft. Circumferential suction of air-fuel mixture enables the cylinder to cool itself and to burn the fuel at the energy center effectively. An incoming stream of air-fuel mixture rotates the impeller on the piston which acts as a fan to cool the cylinder walls. The impeller blades deflect the flame from reaching the cylinder walls and acts as a thermal barrier between the energy center and cylinder walls. A high intensity compression swirl (HICS) is created at the end of the compression stroke to ensure that the fuel combustion is efficient and instantaneous release of maximum energy.

The present disclosure is directed to various embodiments of systems and methods for cooling a combustion chamber of an engine. One method includes introducing fuel into the combustion chamber of an engine having an energy transfer device that moves through an intake stroke, a compression stroke, a power stroke, and an exhaust stroke. The method further includes monitoring a temperature of the combustion chamber. When the temperature reaches a predetermined value, the method also includes introducing coolant into the combustion chamber only during at least one of the power stroke and the exhaust stroke of the energy transfer device.

A thermoelectric power generator is disclosed for use to generate electrical power from heat, typically waste heat. An intermediate heat transfer loop forms a part of the system to permit added control and adjustability in the system. This allows the thermoelectric power generator to more effectively and efficiently generate power in the face of dynamically varying temperatures and heat flux conditions, such as where the heat source is the exhaust of an automobile, or any other heat source with dynamic temperature and heat flux conditions.
摘要:
In a motor vehicle having exhaust-gas recirculation, the fluid of the air-conditioning circuit is used to cool the coolant of a dedicated hydraulic circuit, which in turn cools the recirculated exhaust gases in a two-stage (HT,LT EGR) heat exchanger, thus increasing engine gain by replenishing in order to reduce NOx emissions. The method comprises differentiated control strategies for these circuits, as a function of vehicle driving conditions, continuous modes and transient braking and acceleration modes, in order to compensate for the consumption of the compressor (C) of the air-conditioning circuit. The circuits comprise a heat exchanger (EXCH STORE) for heat exchange between the air-conditioning fluid and coolant, provided with a bypass, capable of accumulating and releasing cold energy, and, optionally, a line for condensing the water vapour of the exhaust gases and for reinjecting the condensed water to the intake.
