Title: Exhaust gas recirculation device
Inventor: SHIBATA HITOSHI
IPC: F02M25/07
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce adhesion of particulate to the interior of an intake pipe and to eliminate a need to perform after-processing of particulate accumulated at a filter by a method wherein the end part on the exhaust pipe side of an exhaust gas conduit, communicated with an intake system, is protruded in an exhaust pipe and the terminal opening thereof is pointed to the direction of a flow of exhaust gas. SOLUTION: A part of exhaust gas discharged in an exhaust pipe 3 from an engine 1 flows through the terminal opening 42 of an EGR conduit 4 to an intake pipe and is mixed with intake air. The maximum combustion temperature of the engine 1 is decreased by the mixture and oxidation reaction of nitrogen is suppressed. In this case, the end part 41 of the EGR pipe 4 is extended through an exhaust pipe 3 wall and protruded in the exhaust pipe 3, and bent in an L-shape to the opposite side to the engine 1 at the central part of the cross section of the exhaust pipe 3, and a terminal opening 42 is pointed to a spot situated downstream of an exhaust gas flow. This constitution reduces an amount of particulate adhered and accumulated on the intake pipe and eliminates a need to mount a member for capturing the particulate in the EGR conduit 4.

CONSTITUTION:A recess 8 formed on the gate arranging part of a silicon substrate 1 is formed by etching the substrate before a first gate oxide film 51 is formed. It is desirable to form the depth of the recess 8 in the degree of the thickness of a floating gate 52. The width of the recess 8 is formed larger than the width of a gate 5. After the recess is formed, a first gate oxide film 51 is formed in the bottom of the recess 8 by a thermally oxidizing method, and the gate 5 is formed thereon. With such structure, the film 51 and the gate 52 of the gate 5 are disposed substantially in the recess, and the size protruding form the surface of the substrate 1 is reduced. Thus, the surface of a PSG film 6 is flattened as shown. Since the shape of a aluminum wirings 7 is formed along the surface of the flattened film 6, wire faults are reduced.

Abstract: PURPOSE: To reduce noise and carry out downsizing by providing a communicating part for communicating a hollow part for accumulating high pressrue fluid and each cylinder with each other on a position near a confining part where a piston attains from a suction port to a bottom dead point. CONSTITUTION: When each piston 20 attains a bottom dead point and becomes in a confining condition, a high pressure fluid which is packed in a hollow part 13 is supplied from a communicating part 16 into a cylinder 12 corresponding to the piston 20, and pressure is applied on inner pressure of a cylinder 12. At this time, since a small hole 18 is provided in the vicinity of one piston 20 which precedes the other piston 20 in a confining condition, the small hole 18 is communicated with a notch, and thereby, the high pressure fluid is supplied from the notch of a discharging port 10 into the hollow part 13 through the small hole 18, and the high pressure fluid which is discharged for pressurization in the confining part is replenished.  When the piston 20 is rotated, an intake/ exhaust passage 17 is communicated gradually, discharging pressure is increased smoothly following with pressurization effect. It is thus possible to prevent generation of reverse flow in the confining part.
