A cooling apparatus of a vehicle of the invention comprises an engine cooling system, a device cooling system, and a connection apparatus configured to connect an engine circulation circuit of the engine cooling system and a device circulation circuit of the device cooling system to each other such that heat exchanging liquid cooled by a device radiator of the device cooling system, is supplied to an engine passage formed in an internal combustion engine without flowing through a device passage formed in the device including at least one of a motor of the vehicle, a battery for storing electric power to be supplied to the motor, and a power control unit for controlling a supply of the electric power from the battery to the motor.

Methods and systems are provided for a vehicle coolant circuit. In one example, the coolant circuit includes a heater core isolation valve (HCIV) where a status of the HCIV may be diagnosed by intrusively activating a positive temperature coefficient heater in a cooling loop in which the HCIV is arranged. A response of coolant temperature to heater activation may be used to determine a position of the HCIV.

Methods and apparatus consistent with the present disclosure may provide electrical energy and thermal to extraction or separation equipment. Methods and apparatus consistent with the present disclosure may extract and concentrate essential elements plant matter. An amount of wasted heat energy collected from a engine that powers an electrical generator may be provided to an evaporation or separation process when electrical power is provided to extraction or separation processing equipment. Computers or electronics that control equipment consistent with the present disclosure may be remotely controlled via a mobile electronic device, when desired. Such computers or electronics may receive sensor data related to the operation of plat matter extractors, related separation equipment, or other equipment may be used to manage a production line. As such, methods and apparatus consistent with the present disclosure may extract essential elements from cannabis plant matter and process those essential elements into cannabis extracts or isolates.

An engine promoting activation of a catalyst is provided, including an exhaust manifold, an exhaust lead-out path led out from a manifold exit of the exhaust manifold, a catalyst case provided on the exhaust lead-out path, and a catalyst housed in the catalyst case. The exhaust manifold and the catalyst case are extended in the front-back direction of crankshaft extension and disposed side by side orthogonally to the front-back direction. The engine may further include a supercharger attached to the exit of the exhaust manifold, and the catalyst case is attached to a turbine exit of the supercharger. The engine may further include an exhaust relay pipe attached to the exit of the exhaust manifold, and the catalyst case is attached to a relay pipe exit of the exhaust relay pipe. The engine may further include an exhaust throttle device provided on an exhaust downstream side of the catalyst.

An EGR (exhaust gas recirculation) cooler includes a cylinder block having a mounting space and having a coolant inlet in which a coolant can flow into the mounting space and a coolant outlet in which the coolant can be exhausted. A cover plate covers the mounting space and forms an exhaust inlet though which the exhaust gas can flow in and an exhaust outlet through which the exhaust gas can be exhausted. Tubes are mounted in the mounting space and through which the exhaust gas can flow. An inlet tank is mounted in the mounting space and is configured to distribute the exhaust gas flowing through the exhaust inlet of the cover plate to the tubes. An outlet tank is mounted in the mounting space and is configured to guide the exhaust gas exhausted from the tubes to the exhaust outlet of the cover plate.

A cooling arrangement for a WHR-system in a vehicle, includes a first cooling circuit including a first radiator in which a circulating coolant is cooled, and a second cooling circuit including a second radiator in which a coolant is cooled to a lower temperature than the coolant in the first radiator. A condenser inlet line directs coolant from one of the cooling circuits to a condenser to provide cooling for a working medium flowing therethrough. A cooling adjusting device adjusts the temperature of the coolant in the inlet line to the condenser by the coolant in the other cooling circuit based on information received about the coolant such that the coolant in the condenser inlet line provides the estimated suitable cooling of the working medium in the condenser.

A charge air cooler includes a battery of round tubes that extend between a first header plate and a second header plate arranged at a first end and a second end, respectively, of the charge air cooler. Stresses in corner tubes caused by differential thermal expansion between the tubes and side plates of the charge air cooler are reduced by having a reduced thickness over a portion of the header plates, or by directing a portion of the coolant through the side plates, or both.

An EGR cooler includes a tube assembly formed by stacking a plurality of tubes in which exhaust gas flows and a cover plate having a mounting portion formed concavely to mount the tube assembly thereon. A baffle is mounted at the tube assembly and adjusts flow of coolant inflow from a cylinder block. An inlet cover is installed on a first side of an outer surface of the cover plate to supply the exhaust gas to each tube and an outlet cover is installed on a second side of outer surface of the cover plate to exhaust the exhaust gas from each tube. At least one coolant passage in which the coolant flows is formed between the plurality of tubes.

An EGR (exhaust gas recirculation) cooler includes a cylinder block having a mounting space and having a coolant inlet in which a coolant can flow into the mounting space and a coolant outlet in which the coolant can be exhausted. A cover plate covers the mounting space and forms an exhaust inlet though which the exhaust gas can flow in and an exhaust outlet through which the exhaust gas can be exhausted. Tubes are mounted in the mounting space and through which the exhaust gas can flow. An inlet tank is mounted in the mounting space and is configured to distribute the exhaust gas flowing through the exhaust inlet of the cover plate to the tubes. An outlet tank is mounted in the mounting space and is configured to guide the exhaust gas exhausted from the tubes to the exhaust outlet of the cover plate.

A cleaning system is disclosed that includes a vehicle that has a cooling system for circulating a coolant, a diverter coupled with the cooling system that is configured to divert the coolant through a heat exchanger, a pump configured to pump a cleaning solution through the heat exchanger so that the heat exchanger heats the cleaning solution without mixing the coolant and the cleaning solution, and a rotary head cleaner in fluid communication with the heat exchanger for receiving the cleaning solution and applying the cleaning solution to a floor.
