摘要： The exhaust gases flow through a duct (1) housing a diesel particle filter (4) and a dust collector electrode (3) to which fine particles adhere. The charged electrode has a central charge electrode (20) and a support connector (21) with a glass insulation sleeve (22) attached to the wall through an insulated bush (11).

摘要： According to the present invention, a fuel injection apparatus includes a casing having a control pressure chamber for storing fuel supplied from fuel passage, a needle valve to which fuel stored in the control pressure chamber applies pressure in the valve closing direction, a valve device for interrupting communication between the fuel passage and the control pressure chamber to seal fuel in said control pressure chamber, and volume changing device for expanding volume of the control pressure chamber after fuel is sealed in the control pressure chamber by the valve device. According to the above fuel injection device, pressure in the control pressure chamber is reduced while the fuel is stored therein by the volume changing device, the nozzle needle is lifted, and injection is started. For this reason, it is not necessary to supply surplus fuel in addition to the injection fuel during the fuel injection. In this way, the fuel supply pump is made smaller in size, and efficiency for use of supplied fuel can be improved. Further, since high-pressure fuel is not discharged from the fuel injection apparatus, pulsation within the common rail can be suppressed, and fuel injection can be stabilized.

摘要： The unit (10) has a valve element (21) to open and close a valve seat (13) in a fuel injection hole (14). A moving core (22) is formed in one piece with the valve element. A first coil (32) at one end of the moving core magnetizes a first fixed core (31) and pulls the moving core to open the valve. A second coil (42) at the other end of the moving core magnetizes a second fixed core (41) and pulls the moving core to close the valve. The second coil is excited before the end of the excitation of the first coil. A valve closure stroke ends the excitation of the second coil, before the valve element sits on the valve seat.

摘要： To provide a fuel injection pump which can sufficiently and stably supply fuel to a fuel pressurization chamber during a fuel intake stroke, a plunger chamber (23), a spill port (29) and a spill passage (33) are mutually communicable, while a reflux passage (34), an intake gallery (15), an intake passage (31), an intake port (27) and the plunger chamber (23) are mutually communicable. A reflux passage (34) communicates with a damping chamber (35) through a communication passage (35a). The spill passage (33) and the reflux passage (34) communicate with each other, and when a spill valve (40) opens, high-pressure fuel within the plunger chamber (23) spills from the spill valve (40) and into the intake gallery (15) through the reflux passage (34), causing pulsation having a pressure level difference to the spill fuel. When the pulsation wave passes through the damping chamber (35), as the level difference in the pulsation wave is reduced, a sufficient quantity of fuel can stably be supplied from the intake gallery (15) to the plunger chamber (23).

摘要： Exhaust gas emission control system for an automobile engine (1) with an exhaust pipe (9) equipped with a nitrogen oxide reduction catalyst (36) comprises a reducing agent generator (28) with a semipermeable membrane for separating a low-carbon component from fuel from the engine's fuel tank (25) and an injector (37) for injecting the low-carbon component into the exhaust pipe upstream of the catalyst. An independent claim is also included for purifying exhaust gases by supplying fuel to a reducing agent generator with a semipermeable membrane for separating a reducing agent from the fuel, injecting the reducing agent into the exhaust pipe of an internal combustion engine upstream of a nitrogen oxide reduction catalyst, and purifying exhaust gas from the engine with the catalyst using the injected reducing agent.
