The present invention discloses an automatic cooling system based on stirling engine for combustion engine. The system is configured to utilize thermal energy from the temperature difference between the engine and a radiator to feed the stirling engine. The stirling engine drives a coolant pump to circulate a coolant between the engine and the radiator. If the temperature difference between the combustion engine and the radiator is high, the stirling engine automatically drives the coolant pump and circulates the coolant at high speed. If the temperature difference between the combustion engine and the radiator is low, the stirling engine automatically drives the coolant pump and circulates the coolant at low speed, until the temperature difference between the engine and radiator within a threshold point. Therefore, there is no need for a thermostat and a water pump coupled with the engine.

The invention relates to a method of fluid exchange using a separation apparatus, in controlled fluid communication with an inlet and an outlet. Opening of the inlet enables fluid communication with the separation apparatus, exchange of fluid (a first fluid exchange) of a first volume of fluid, sealing/closing preventing further fluid communication. Opening of the outlet to be in fluid communication with the separation apparatus enables exchange of fluid (a second fluid exchange) through the open outlet of a second volume of fluid. In the method, the outgoing volume of fluid and the incoming volume of fluid in each exchange are substantially similar and there is substantially no loss of pressure by virtue of the exchange. The invention also relates to a separation apparatus, including a separation chamber and a control system.

The present invention provides a method of operating an engine (14) having one or more cylinders (16) each having a piston (18) within the cylinder (16) and each piston (18) having an expansion stroke and a return stroke and a top dead center (TDC) position and a bottom dead center position (BDC) and said engine (14) employing a working fluid (WF) and a heat exchange fluid (HEF), comprising the steps of: introducing the HEF during the return stroke of the engine; introducing the working fluid (WF) during the expansion stroke of the engine; causing the exhaust valve to be opened at or near bottom dead center of the piston BDC; delivering the HEF to the cylinder (16) after the exhaust valve has been opened; and closing the exhaust valve before TDC, such as to allow the working fluid to be compressed by the piston within the cylinder. The invention also provides an engine (14) capable of being operated in accordance with the method.
