A hybrid vehicle has an internal combustion engine and an electric drive, each with a cooling circuit with a heat transfer medium and a cooler. A pre-heating circuit is provided between the cooling circuits and it is thermally coupled to the cooling circuit of the electric drive via heat coupling element as a shared component, for a controlled heat exchange between the heat transfer media of the two cooling circuits. The pre-heating circuit has an electrical auxiliary heater, which is connected to the heat coupling element in series, such that the heat transfer medium of the first cooling circuit likewise flows through the electrical auxiliary heater. The electrical auxiliary heater is arranged and designed such that heat generated by the electrical auxiliary heater can be transferred, where necessary, into at least one of the two cooling circuits.

An engine system is provided, including an engine, a circulation system that circulates coolant through a water jacket, and a controller. The circulation system includes a radiator passage including a heat exchanger, a bypass passage, a flow rate control device, and a thermally-actuated valve. The engine has a spark plug that forcibly ignites an air-fuel mixture. The engine switches between a first combustion in which the air-fuel mixture combusts without the forcible ignition, and a second combustion in which the air-fuel mixture combusts by the forcible ignition. The controller is electrically connected to the flow rate control device, and when the engine performs the first combustion, the controller controls the flow rate control device to adjust the flow rate of the coolant flowing through the water jacket according to the engine load, by closing the radiator passage and adjusting the flow rate of the coolant flowing through the bypass passage.

An engine cooling system has a coolant control valve unit and includes a cylinder head disposed on a cylinder block. The coolant control valve unit is configured to receive coolant from a coolant outlet side of the cylinder head to control coolant distributed to a heater and a radiator and to control coolant exhausted from the cylinder block. A control unit is configured to determine a heating priority mode according to operation conditions and to substantially open a first coolant passage corresponding to the heater by controlling the coolant control valve unit in the heating priority mode.

A control apparatus in a cooling system has an opening schedule of a degree of opening of each of a plurality of outflow ports in a control valve including at least a heater cut mode, a heater passing water mode, a fully closed mode, and a switching mode in which the opening and closing of an air conditioning outflow port is switched in a state in which at least one outflow port of a radiator outflow port and a bypass outflow port is opened and switches the heater cut mode and the heater passing water mode via the switching mode.

An integrated coolant heating module for a vehicle includes a water-cooled condenser having a plurality of refrigerant inlet/outlet ports and a plurality of coolant inlet/outlet ports, and exchanging heat between coolant and refrigerant that circulate therein, a water heater having a plurality of mounting parts, the water heater being coupled to the water-cooled condenser and selectively heating the coolant passing through the water-cooled condenser, a multi-way valve coupled to a mounting part of the water heater, and controlling a direction of flow of the coolant, and a water pump coupled to a mounting part of the water heater, having a first side connected to the multi-way valve and a second side connected to a second coolant inlet/outlet port of the water-cooled condenser, and creating a pressure of the coolant between the multi-way valve and the water-cooled condenser.

A method of controlling a fluid heater control system for a locomotive, the fluid heater control system including a heater assembly including a water pump and a heating element, the method including determining if a fuel pump of the locomotive is on, if the fuel pump is off, activating the heater assembly, running the water pump for a first predetermined period of time, determining if a temperature of the fluid is greater than a first predetermined threshold, and if the temperature of the fluid is greater than the first predetermined threshold, deactivating the water pump for a second predetermined time period.

A heater comprises a combustion chamber and a jacket extending about the combustion chamber. There is a fan having an output which communicates with the combustion chamber to provide combustion air. There is also a fuel delivery system having a variable delivery rate. A burner assembly is connected to the combustion chamber. The burner assembly has a burner mounted thereon adjacent the combustion chamber. The burner receives fuel from the fuel delivery system. There is an exhaust system extending from the combustion chamber. An oxygen sensor is positioned in the exhaust system to detect oxygen content of exhaust gases. There is a control system operatively coupled to the oxygen sensor and the fuel delivery system. The control system controls the delivery rate of the fuel delivery system according to the oxygen content of the exhaust gases.

A vehicle comprising an interior; a heat source in thermal communication with the interior; a source of ultraviolet light disposed to emit the ultraviolet light into the interior; and a controller in communication with the heat source and the source of the ultraviolet light, the controller configured to cause (i) the heat source to increase a temperature of the interior, (ii) the source of the ultraviolet light to emit the ultraviolet light into the interior, or (iii) both (i) and (ii) upon receiving a command from a remote user interface. The vehicle can further include a combustion engine that combusts fuel to propel the vehicle. The vehicle can further include a battery in electrical communication with the source of the ultraviolet light and in communication with the controller, the battery having a voltage.
