Apparatus and method are provided for two-phase dielectric cooling of an electronic device. The apparatus includes a coolant flow path, a vapor condenser and one or more vapor fans. The coolant flow path is in fluid communication with the electronic device, where liquid dielectric coolant within the flow path vaporizes upon contacting the electronic device, forming dielectric coolant vapor, and thereby facilitating cooling of the electronic device. The vapor condenser is also in fluid communication with the coolant flow path and facilitates condensate formation from the dielectric coolant vapor. The one or more vapor fans are disposed within the flow path to actively move dielectric coolant vapor into contact with the vapor condenser, and thereby enhance cooling of the electronic device by facilitating coolant condensate formation and thus recirculation of the coolant condensate as liquid dielectric coolant.

A Fuel Fractionation System (FFS) and associated methods to generate and store a fuel for internal combustion engines is provided. FFS provides a distillation column assembly to distill liquid fuel to form a volatile light fraction secondary fuel. The distillation column assembly includes a vaporization module to vaporize a feed fuel in the distillation column and includes a condensation module to condense heavy fraction components of the vaporized feed fuel. FFS also provides a controller positioned to control the vaporization of feed fuel in the distillation column to thereby control the separation of the feed fuel into light fraction fuel and heavy fraction fuel components, and positioned to control the condensation of the heavy fraction components so that fuel exiting a light fraction output port in the distillation column is substantially light fraction fuel components by volume.

A combustion control method for the rich pulse control of Diesel engines with Lean NOX Trap systems includes identifying areas within a Diesel engine operating regime in which reduced recirculated exhaust gas and air with increased pre-mixed combustion is effective in providing fuel rich combustion, and a second, lower load, region in which low temperature combustion is particularly desirable.

A turbocharged engine control system is provided that comprises an exhaust gas after-treatment system and a variable-capacity turbocharger. The turbocharged engine control system is configured to estimate a clogging ratio of the exhaust gas after-treatment system based on an equivalent surface area of the exhaust gas after-treatment system. A correction value is determined based on a turbine outlet pressure and the correction value is added to the clogging ratio. A target nozzle opening value is corrected such that the nozzle opening value increases as the exhaust gas after-treatment system becomes more clogged. Consequently, as the exhaust gas after-treatment system becomes clogged, the increase in pressure on the inlet side of the exhaust turbine (which acts as back pressure with respect to the engine) is suppressed and the increase in the internal EGR ratio caused by residual gas is also suppressed.

A system and method for putting a fuel cell vehicle into a performance mode by preloading sub-systems in the fuel cell system so that high power is available from the fuel cell stack quicker than during normal fuel cell system operation. For example, if a driver activates a vehicle performance mode, the fuel cell system can respond by, for example, increasing the compressor speed, increasing anode recirculation, increasing air and cooling fluid flow through the radiator, increasing battery state-of-charge, etc. Thus, when the driver requests the high power after the system is in the performance mode, the system is able to deliver the desired power immediately or at least quicker and for a longer time period.

The invention relates to a process and apparatus that treats waste water, in particular waste water containing surfactants and including grey water, for local reuse. According to the invention, the process comprises a) collecting waste water in a reservoir; b) injecting gas into waste water from the reservoir to form bubbles in the waste water; c) separating the bubbles, and any entrained contaminants, from the waste water; d) drying the separated bubbles and returning any water recovered from the dried bubbles to the waste water undergoing treatment; e) optionally repeating steps b) to d) to achieve the desired purification of the waste water; and f) collecting the purified waste water. The invention provides a robust process and a mechanically simple apparatus that does not require regular replacement of chemicals or filters, yet is capable of treating waste water locally, and in particular grey water for household reuse.

A burner is provided which includes a tile surrounding an opening of the tile extending along a burner axis, the tile including a front side and a rear side, wherein the rear side has an air inlet connected to the opening for feeding air into the opening, and the front side has a discharge outlet connected to the opening for discharging a flame into a surrounding area. The burner includes at least one oxygen lance extending along the burner axis in a first recess of the tile, and the oxygen lance having an ejection nozzle at an end region of the lance for ejecting oxygen, wherein the at least one oxygen lance is mounted with the ejection nozzle positioned along the burner axis to be adjustable between an uppermost position and a lowermost position via a zero-position in between the uppermost position and the lowermost position.

A fuel cell system comprising a fuel cell stack, a fuel recirculation line provided with a jet pump and a valve controlled by a control unit based on the anode-cathode pressure differential such that the valve is closed to reduce or stop fuel supply when the anode-cathode pressure differential reaches a predetermined value, and opened again to circulate more fuel through the jet pump when the pressure differential is below a predetermined value, to create a pulsed fuel supply that improves the fuel recirculation at low loads and ensures adequate water removal from the anode flow field channels.

Combustion chamber structure of a direct injection type diesel engine arranged such that generation of black smoke or degradation in fuel efficiency can be avoided as much as possible even if the recirculation quantity of exhaust gas is increased. In the direct injection diesel engine having a cavity (10) provided in the top surface of the piston (9) to constitute the majority of the combustion chamber and injecting fuel radially from the center of the ceiling portion of a cylinder toward the inner circumferential surface of the cavity (10) to cause it to self-ignite, a bored portion (24) recessed from the top surface of the piston (9) to form a step difference is provided in the outer circumferential part of the opening of the cavity (10). Outer circumferential part of the bottom face ofthe bored portion (24) ascends to describe a gentle curved surface toward the radial outside and reaches the top surface of the piston (9). An inlet lip (11) is formed at a position lower by one stepthan the top surface of the piston (9) by the inner circumferential portion of the bottom face of the bored portion (24) and the combustion chamber wall face portion (12) rising from the bottom face of the cavity (10).

A valve has a body, a fluid inlet duct and two fluid outlet ducts delimited by the body, an intersection formed at an area where the fluid inlet duct opens into the two fluid outlet ducts, and a butterfly valve disposed in the intersection. The butterfly valve is operable to be actuated between a first extreme position in which the butterfly valve directs the fluid mainly toward the first outlet duct and a second extreme position in which the butterfly valve directs the fluid mainly toward the second outlet duct. In the first extreme position, the butterfly valve has a first portion partially blocking the second outlet duct and, in the second extreme position, the butterfly valve has another portion blocking the first outlet duct.
