Abstract:
A system (200) includes an emulsification device (210), a processed fuel tank (250), an emulsification recirculation line (254), and a control module (205). The emulsification device is configured to selectively receive a liquid mixture of water and hydrocarbon fuel and produce batches of emulsified fuel. The processed fuel tank is configured to selectively receive and store the emulsified fuel. The control module is configured to monitor one or more operating parameters and execute one or more operating modes. The operating modes include a bypass mode configured to provide an engine (102) with the hydrocarbon fuel, an emulsification recirculation mode configured to continually recirculate emulsified fuel through the emulsification device and the processed fuel tank via the emulsification recirculation line, a run mode configured to operate the engine with emulsified fuel, and a suck back mode configured to return semi-stable emulsified fuel back to the processed fuel tank.
Abstract:
Systems, apparatuses and methods ("utilities") for use in "internally" cooling the compressor of a gas turbine engine so as to approximate isothermal compression and thereby increase the power and/or efficiency of the engine. In one arrangement, a "cooling jacket" or heat exchanger having coolant circulating or passing therethrough may be mounted around an outer surface of the compressor to absorb heat or thermal energy generated from the compressor. In another arrangement, the stator blades of the compressor may include passages through which a coolant may be circulated or passed to absorb heat from air passing through the compressor.
Abstract:
An exhaust heat recovery system (18) includes first and second loop heat pipes (20 and 30). The first loop heat pipe (20) recovers exhaust heat downstream of a catalyst (5) in an exhaust passage (4) of an internal combustion engine (1) to exchange heat with the catalyst (5). The second loop heat pipe (30) recovers heat of the catalyst (5) to exchange heat with coolant that is once delivered from the internal combustion engine (1).
Abstract:
The present invention relates to a cooling structure for cooling an liquid-cooled internal combustion engine where said engine comprises an EGR passage interposed between an exhaust manifold structure and an inlet manifold structure of said engine. Said cooling structure comprising a first cooling system and a second cooling system. Said first cooling system comprises at least one radiator and a liquid coolant circulatable through said radiator and said internal combustion engine for cooling said internal combustion engine. A flywheel housing for said internal combustion engine is provided with at least a portion of said second cooling system.
Abstract:
An anti-explosion and anti-fire system (5) is disclosed, system (5) comprising an encapsulant (20) disposed to cover high temperature surface portions (10) of a component (15); a conduit (25) in thermal connection with encapsulant (20); and a heat transfer fluid (30) disposed within conduit (25). A diesel engine (15A) is disclosed for an underground mine, engine (15A) comprising an encapsulant (20) disposed to cover high temperature surface portions (10) of a cylinder head (15B); a conduit (25) in thermal connection with encapsulant (20); and a heat transfer fluid (30) disposed within conduit (25). A method for encapsulating high temperature surface portions (10) of a cylinder head (15B) is disclosed, the method comprising positioning a conduit (25) adjacent head (15B); positioning an encapsulant (20) in thermal connection with head (15B) and conduit (25); and transferring heat from high temperature portions (10) to prevent gasses, coal dust, fuel, oils or other combustible material in an underground mine from contacting portions (10) at temperatures above an explosion or fire safety limit.

Abstract:
Water of low temperature from a feed pump (15) is divisionally fed to an auxiliary evaporator (17) covering an exhaust port (16) extending from the combustion chamber of an internal combustion engine (E) and to a main evaporator (11) located downstream of the exhaust port (16). The direction of water flowing through the auxiliary evaporator (17) is parallel with the direction of exhaust gas flow, whereby the upstream portion of the exhaust port (16), which tends to be high in temperature, is effectively cooled by water of lower temperature, thus inhibiting the heat from escaping from the upstream portion of the exhaust port (16). The direction of water flowing through the main evaporator (11) is opposed to the direction of exhaust gas flow, thereby securing the temperature difference between water and exhaust gases throughout the length of the water passageway of the main evaporator (11), and increasing the heat exchange efficiency.
