In one embodiment, a method for cooling an engine damper, including converting a gas to a liquid, and cooling an engine damper by passing the liquid through a tube portion located between fan air flow and the engine damper.

A split cycle internal combustion engine includes a combustion cylinder accommodating a combustion piston and a compression cylinder accommodating a compression piston. The engine also includes a controller arranged to receive an indication of a parameter associated with the combustion cylinder and/or a fluid associated therewith and to control an exhaust valve of the combustion cylinder in dependence on the indicated parameter to cause the exhaust valve to close during the return stroke of the combustion piston, before the combustion piston has reached its top dead centre position (TDC), when the indicated parameter is less than a target value for the parameter; and close on completion of the return stroke of the combustion piston, as the combustion piston reaches its top dead centre position (TDC), when the indicated parameter is equal to or greater than the target value for the parameter.

An apparatus of decreasing intake air temperature of an engine includes: a first cooling circuit including a compressor, a condenser, a first expansion valve, and an evaporator disposed along a first cooling line through which refrigerant flows; a second cooling circuit including the compressor, the condenser, a second expansion valve, and a chiller disposed along a second cooling line through which the refrigerant flows; and a third cooling circuit including an electric water pump, the chiller, an intercooler, and a radiator disposed along a third cooling line through which coolant flows.

A condensation cooling system for motor vehicles is presented. The system, in principal part, comprises a liquid-to-liquid heat exchanger for circulating a first coolant, a coolant tank for circulating a second coolant, and a condensing panel or surface, where the condensing panel is part of the coolant tank and also functions as a vehicle body panel. These components are arranged in two circuits, i.e. an engine cooling circuit in which a first coolant is circulated and a vapor condensing circuit in which a second coolant is circulated. The two cooling circuits are interconnected by the coolant tank where the heat exchanger is positioned within the coolant tank such that it is immersed in the second coolant. The coolant tank may also be equipped with pressure release valves, electric fans and diffuser plates to control pressure and manage air and vapor flow internally within the tank.

A connector for an engine cooling system is provided. The connector may be located in a chamber with two inlets and an outlet. The connector may include a thermostatic valve. A temperature sensitive element may move the thermostatic valve between an open and closed position. A pressure relief valve may also be incorporated into the thermostatic valve. An engine cooling system comprising the connector is also provided.
