摘要： A method of modifying the oil cooling system of a diesel engine includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having a configuration adapted to match the mounting configuration of the oil passages of the original equipment liquid-to-liquid heat exchanger. The manifold has an oil outlet port directed to a remotely mounted oil cooler. The manifold also has a water passage having a configuration that is adapted to match the mounting configuration of the water passages of the original equipment liquid-to-liquid heat exchanger. The water passage causes the entirety of the flow of water to be discharged back to the water cooling system of the engine where it is circulated by the water pump through the water cooling passages in the engine.

摘要： An aircraft propulsion system comprising a reciprocating liquid cooled engine housed within the fuselage driving twin fuselage mounted ducted-fans is disclosed. The propulsion system may be liquid cooled with a liquid cooled exhaust and at least one turbocharger. The ducted-fans may run fan blade tip speeds of up to 97% Mach driven by a near constant RPM engine through a continuously variable transmission. The propulsion system may be low noise and may meet environmental standards typical in the automotive industry.

摘要： An internally cooled internal combustion piston engine and method of operating a piston engine is provided, with the combination of liquid water injection, higher compression ratios than conventional engines, and leaner air fuel mixtures than conventional engines. The effective compression ratio of the engines herein is greater than 13:1. The engines may employ gasoline or natural gas and use spark ignition, or the engines may employ a diesel-type fuel and use compression ignition. The liquid water injection provides internal cooling, reducing or eliminating the heat rejection to the radiator, reduces engine knock, and reduces NOx emissions. The method of engine operation using internal cooling with liquid water injection, high compression ratio and lean air fuel mixture allow for more complete and efficient combustion and therefore better thermal efficiency as compared to conventional engines.

摘要： A heat transfer system has an energy converter, a heat transfer medium, a transfer part, and a heat exchanger. The energy converter converts an energy of an energy source into an energy in a different state and generates a heat while converting the energy. The heat transfer medium is in a liquid state and receives the heat from the energy converter. The heat exchanger dissipates the heat from the heat transfer medium to an outside of the heat transfer system. The heat transfer medium contains H2O and a solute compatible with the H2O. The solute has a molecular structure including two hydroxyl groups. A length of a binding chain between an oxygen atom of one of the two hydroxyl groups and an oxygen atom of an other of the two hydroxyl groups is shorter than a length of a binding chain between two hydroxyl groups of an ethylene glycol molecule.

摘要： The cooling device according to the present invention includes an electric water pump for circulating cooling water through an internal combustion engine of a vehicle, and controls the discharge flow rate of the electric water pump as follows. Until the cooling water temperature. TW reaches a warm-up completion determination temperature, the cooling device increases the discharge flow rate along with an increase of the cooling water temperature TW. After the cooling water temperature TW reaches the warm-up completion determination temperature, the cooling device controls the discharge flow rate so as to bring the combustion chamber wall temperature TCYL toward a target temperature. Thereby, the cooling device can warm up the internal combustion engine more efficiently, and improve the combustion performance of the internal combustion engine after the completion of warm-up.

摘要： An air/oil-cooled internal combustion engine capable of increasing accuracy in detection of the temperature of the air/oil-cooled internal combustion engine by a temperature sensor and carrying out the warm-up operation after the start-up of the air/oil-cooled internal combustion engine favorably. The air/oil-cooled internal combustion engine includes cooling fins that are provided on the circumferences of a cylinder block and a cylinder head; and a cooling passage that is provided in a combustion chamber upper wall covering a combustion chamber of the cylinder head and is used for cooling the combustion chamber upper wall with lubrication oil. The air/oil-cooled internal combustion engine has a temperature sensor configured to detect the temperature of the air/oil-cooled internal combustion engine by detecting the temperature of oil. The temperature sensor faces a cooling oil outlet portion of the cooling passage.
