摘要： PROBLEM TO BE SOLVED: To prevent fluctuation of a fuel injection amount for the same valve open time of an injector by restraining pressure pulsation of fuel inside a fuel piping in a fuel supply system of an internal combustion engine. SOLUTION: In this system, pressure mitigating device 5 connected to a high pressure fuel piping is provided, and damper chamber 11 is formed inside the pressure mitigating device 5, valve bodies 12, 13 are provided to openings 9a, 10a of partitions 9, 10, respectively, whereby urging in a valve close direction is always performed by a spring 14. When a high pressure part comes to an inlet of the damper chamber 11, the valve element is positioned to open the valve, and the high pressure is enclosed and absorbed in the damper chamber 11. When a low pressure part comes to the inlet, the high pressure part is discharged gradually via a restriction opening 12a or 13a and the low pressure part is canceled. Accordingly, pressure pulsation of a fuel can be reduced.

摘要： PURPOSE: To prevent generation of deposite, while preventing adhesion of drops of lubricating oil included in blowby gas through the contraflow of intake. CONSTITUTION: A connection port 4 of a blowby gas passage communicated with a crank case of an engine is opened to a wall surface of an intake passage (serge tank) 3 on a downstream side of a throttle valve 2 provided in an intake passage 1 of an internal combustion engine. Plate-like guide ribs 7, 7 are projected from the wall surface of the intake passage inward so as to form a guide groove 8 for guiding intake flow passing near the connection port 4 from the opening position of the connection port 4 to the wall surface of the intake passage on the downstream side thereof. Spiral contraflow is not generated since the intake flow inside the guide groove 8 is guided by means of the guide ribs 7. Blowby gas containing drops of lubricating oil is scattered therein. The oil drops are not included in the spiral contraflow, so that deposite is not generated on a throttle valve 2.

摘要： PURPOSE:To efficiently separate water by turning the air contg. water in a cylindrical casing to centrifugally separate and discharge the large-diameter water droplet and introducing the remaining air into a small-diameter air discharge passage to separate the small-diameter water droplet. CONSTITUTION:A spiral flow generator 32 is coaxially provided at one end in the cylindrical casing 31, and the air introduced into the casing 31 from an upstream air passage 12 is turned by the spiral flow generator 32 to centrifugally separate water contained in the air. The separated water is discharged to the outside of the casing 31 through a discharge passage 34 formed on the inner peripheral wall of the casing 31. A cylindrical air discharge passage 33 having a smaller diameter than the casing 31 is provided coaxially with the spiral flow generator 32 with one end opened and opposed to the generator. At least the other end of the discharge passage 33 is communicated with the discharge passage 34, and a downstream air passage 41 is allowed to pierce the wall of the passage 33 and opened. Consequently the water in the air passage is efficiently separated and removed.

摘要： PROBLEM TO BE SOLVED: To make compatible both deposit restraint in an injection nozzle of an injector and excellent fuel consumption. SOLUTION: A micro-computer 21 brings an operation parameter to a value of moderate combustion, e.g. a timing lag side when in ignition timing, in accordance with lowering of an engine speed detected by an engine speed detecting sensor 301, i.e., in accordance with prolongaion of an injection interval, restrains solidification (depodit formation) of a liquid phase component by heating when the injection interval is long to bring the condition where fuel existing in the injector injection nozzle is evaporated during the interval easy to leave depositingly only the liquid phase component, and conducts fast combustion when the injection interval is short to bring the condition where the deposit of the liquid phase component is not allowed to progress excessively and washed away by the next injection. The deposit restraint and the excellent fuel consumption are made compatible by conducting moderate combustion where the deposit is hardly generated, only in the operation condition where deposit generating conditions are all present.

摘要： PROBLEM TO BE SOLVED: To maintain excellent controllability of an injection valve by preventing accumulation of a deposit, and preventing a change with the lapse of time of a fuel injection characteristic such as reduction in an injection quantity in a fuel injection valve. SOLUTION: A circular recess 18 and a radial directional fuel releasing groove 19 connected to the recess are formed by surrounding a fuel nozzle port 12 arranged in a nozzle plate 17. A hollow cylindrical cover 14 is installed around the nozzle plate 17. Since droplet-like fuel sticking to a peripheral part of the fuel nozzle port 12 is sucked and gathered to a corner part 18a by suction force by surface tension acting on the corner part 18a formed of a level difference around the circular recess 18 and is discharged in the radial direction by passing through the fuel releasing groove 19, the fuel does not remain just near the fuel nozzle port 12 so as to prevent residual fuel from accumulating in the vicinity of the fuel nozzle port 12 as a solid deposit by deteriorating at a high temperature after stopping operation.

摘要： PROBLEM TO BE SOLVED: To eliminate the formation of a deposit by paying attention to the fact that NOx which becomes a cause of the formation of a deposit becomes negative ions in gasoline and minus-charging the other bonding components (C=C, C=O, metal M on a surface of a nozzle hole) which are to be essentially bonded to repel them mutually. SOLUTION: A fuel amount adjusting hole 100 of a nozzle hole plate 2 is electrically connected through an injector power supply terminal 101 and a diode 8 because the diode 8 is connected to an electrically continuity part between the fuel amount adjusting hole 100 electrically continued to the injector power supply terminal 101 and the injector power supply terminal 101. Consequently, a minus voltage of the injector power supply terminal 101 is kept.
