摘要:
There is provided a scroll compressor having high overall efficiency and reliability in a wide pressure operating range. A backside excess-suction-pressure region is provided such that pressure higher than suction pressure by a constant value is applied to a backside of scroll members to produce an attractive force to attract both scroll members. A control bypass is also provided for communicating compression chambers with a discharge system only when pressure in the compression chambers is high.
摘要:
An isolated hyperthermostable .beta.-galactosidase gene derived from Pyrococcus furiosus is described. Examples include DNA sequences shown in SEQ ID NO. 2 and SEQ ID NO. 4 and DNAs hybridizable with these DNAs. A method of cloning the hyperthermostable .beta.-galactosidase gene in which each of the above sequences or portions thereof is used as a probe or primer is described. A process for producing a hyperthermostable .beta.-galactosidase by culturing a transformant into which a plasmid containing each of the above genes has been introduced is described. A particularly preferred gene encodes an SDS-resistant hyperthermostable .beta.-galactosidase.

摘要:
In an engine system with a reformer being installed in an exhaust pipe to reform a fuel, a control valve for controlling a flow rate of exhaust gas is provided downstream from an installed position of the reformer in the exhaust pipe. In the engine system with the reformer, since a part of the exhaust gas can be trapped in a space between the reformer and an engine chamber by closing the control valve during an exhaust stroke, the reforming efficiency of the reformer can be heightened.

Disclosed is an engine system with a reformer, the engine system comprising a reformer and driving an engine using, as a fuel, a reformed fuel produced by reforming pre-reformed fuel with the reformer, in which the reformer is connected with both a pre-reformed fuel supply adjustment unit which adjusts the amount of the pre-reformed fuel supplied to the reformer and a reformed fuel supply adjustment unit which adjusts the amount of reformed fuel supplied to the engine, and the reformer is installed adjacent to the engine combustion chamber via the reformed fuel supply adjustment unit.
摘要:
An engine system includes a medium which chemically repeats storage and release of hydrogen to provide an engine system where CO2 emissions can be suppressed and system efficiency is excellent. The engine system includes a hydrogen supply device for producing hydrogen rich gas from a medium which chemically repeats the storage and release of hydrogen, and drives an engine using the hydrogen rich gas produced in the hydrogen supply device as one of the fuels. This engine system is characterized by comprising a waste heat supply device for supplying waste heat of the engine to hydrogen supply device, a generator which generates electricity by power of the engine, an energy storage device for storing electric power produced by the generator, and a motor for converting electric power discharged from the energy storage device into power.
摘要:
An engine system with a reformer, wherein an unreformed fuel is reformed by the reformer mounted in an exhaust pipe, and wherein a reformed fuel containing hydrogen is supplied to an engine. The engine system with a reformer includes a controller which, when the hydrogen generated by the reformer is supplied to the engine, determines a target heat generation beginning timing in accordance with a load applied to an engine, an engine speed, and an air excess ratio of an air-fuel mixture, and which controls an ignition timing of the engine so that a difference between a current heat generation beginning timing and the target heat generation beginning timing of the engine is within a predetermined range.
摘要:
A control apparatus of an engine having a compression ignition combustion mode and a spark ignition combustion mode selects the spark ignition combustion mode when operation conditions fall within a spark ignition operation area set in a spark ignition operation area/compression ignition operation area setting map memory part and selects the compression ignition combustion mode when the operation conditions fall within a switching stable area set in the memory part upon operation by the spark ignition combustion mode. The control apparatus controls to continue the compression ignition combustion mode as long as the operation conditions fall within a compression ignition operation area set in the memory part upon operation by the compression ignition combustion mode.
