摘要： A biomass thermochemical gasification apparatus is provided that can manufacture high-quality fuel gas out of solid biomass in an industrial manner. This fuel gas can be used as fuel for a gas engine and a gas turbine for example and also can be used as synthesis gas for methanol synthesis.A high-temperature combustion gas generation apparatus (101) for biomass operates entirely by biomass and the heat source thereof does not depend on fossil fuel. A coarsely-ground powder biomass (205) subjected to gasification and gasification agent (303) are introduced to a primary gasification reaction room (202) and generate gasification reaction by, as reaction heat, radiation heat from a wall face of the primary gasification reaction room (202) heated by combustion gas (109a) generated in the high-temperature combustion gas generation apparatus (101) and are dissolved. Consequently, the biomass (205) is converted to clean and high-quality generated gas.

摘要： A fuel feeding system is provided for an internal combustion engine to permit appropriate feeding of fuel in accordance with the state of operation of the engine. A fuel line is arranged as a recirculation circuit between a fuel injector and a fuel tank. A low-pressure fuel pump is arranged in an upstream part of the fuel line. A high-pressure fuel pump is arranged between the fuel pump and the injector. A high-pressure regulator is arranged in a fuel line portion on a downstream side of the regulator to control the pressure of fuel delivered from the pump. A bypass line connects another fuel line portion on an upstream side of the regulator and the fuel line portion each other. A switching valve is arranged in the bypass line to open or close the same. A low-pressure regulator controls the pressure of fuel in the fuel line portion at a pressure lower than a control pressure set by the regulator while the switching valve is open. ECU is arranged to perform open/close control of the switching valve so that the switching valve is closed in an ordinary operation state of the engine but is opened in a specific operation state of the engine.

摘要： A stratified burning internal combustion engine according to this invention is equipped with an intake port and a fuel feed device so that stratified tumble flows of different fuel concentrations can be formed in a combustion chamber. An ignition device is provided in the combustion chamber to ignite at least one of the tumble flows, said at least one tumble flow being rich in fuel. To promote the stratified tumble flows, a top wall of a piston has an inclined wall. This makes it possible to strengthen the tumble flows, whereby the stratification of an air-fuel mixture in the combustion chamber can be improved further to permit lean burn at a larger air/fuel ratio.
