A cooling system may include an intercooler configured to heat-exchange a coolant and air, a radiator configured to cool a coolant heated in an engine through heat-exchange with air, a low temperature radiator configured to cool the coolant of the intercooler, a thermostat selectively fluid-connected to the radiator or the intercooler to supply the coolant from the radiator or the intercooler to the engine, a first control valve configured to selectively supply the coolant which has passed through the intercooler to the radiator, a second control valve configured to selectively supply the coolant which has passed through the engine to the intercooler or the first control valve, and a controller configured to control operations of the thermostat, the first control valve, and the second control valve according to a temperature of the coolant of the engine and a temperature of intake air.
摘要:
A heater valve for a diesel fuel system for a vehicle having a main body portion with a fuel inlet and a fuel outlet adapted to be coupled to the vehicle fuel system. A fuel inlet line and a fuel outlet line from the valve are adapted to be coupled to a heat exchanger. A fuel distribution chamber in the valve is in fluid communication with the fuel inlet and the fuel outlet line and a fuel mixing chamber in the valve is in fluid communication with the fuel inlet line and the fuel outlet. A port opens into the mixing chamber and a spring biased valve in the mixing chamber has a restrictor normally restricting the size of the port opening with a valve shaft extending through an opening in a partition wall into the distribution chamber into engagement with a calibrator. A temperature sensor is associated with the valve for sensing the temperature of fuel in the mixing chamber and moving the valve to open both the port and the opening in the partition wall to allow fuel to flow into the mixing chamber from the distribution chamber.

摘要:
According to the method, the gases are circulated in a liquid/gas heat exchanger (2, 12) prior to their entering the internal combustion engine (58) and a high temperature liquid and/or a low temperature liquid is circulated in the liquid/gas heat exchanger (2, 12) in order to heat and/or cool the gases (84) as required. The liquid/gas heat exchanger may comprise a single stage or two stages, that is a high temperature stage and a low temperature stage. It can also be used to cool the recirculating exhaust gases prior to their entering the engine.
摘要:
A water-cooled combustion engine has a pump-operated cooling water circuit passing through the cooler when the engine is hot. The cooler is rendered inoperative by a thermostat-controlled by-pass line when the engine is cold. The heating means for the intake system for the engine has a cooling water chamber whose supply line is fed with heated cooling water. The circuit of the heating means is arranged parallel with the cooling circuit through the by-pass line. This heating means is automatically switched off without additional aids as the engine temperature rises, when the by-pass line is shut off by the thermostat valve.

A temperature control device for the engine may include an air heater configured to heat air introduced into a throttle valve by a flow of engine cooling water, and a valve apparatus configured to cut off the flow of the engine cooling water passing through the air heater at a set temperature range or more, without being supplied with a separate control signal.

摘要:
A continuous hot air intake for carburetor and fuel injection supplied engines that regulates the temperature of air mixing with fuel that is mixed in the carburetor or fuel injector prior to introduction to the cylinders of the engine. The invention includes preferably a heater and associated filter located at the air intake side of the carburetor that is activated by circulating heated fluid contained within the engine cooling system. The heater, in preferred form, is conveniently sized and circular in configuration so as to encircle the filter positioned at the air intake side of the carburetor, however, a circular filter can be used to encircle the heater. The heater and filter are encompassed by a releasably securable cover to hold these components together and in place and to block the entry of dust, dirt or other invading elements.

摘要:
A system, method, and apparatus for controlling intake manifold air temperature (IMAT) of a dual fuel engine are provided. A determination regarding whether IMAT is to be modified is performed, followed by modifying the IMAT by changing flow of coolant in a cooling circuit in fluid communication with a separate circuit aftercooler (SCAC) of a SCAC circuit from a first flow path to a second flow path when it is determined that the IMAT is to be modified. A portion of the first flow path overlaps a portion of the second flow path.
