Title: Oxygen enriching air controller for oxygen enriched engine
Inventor: SUGIURA YASUHITO
IPC: F02M33/00
Filed: 1988-09-30
Abstract: PURPOSE:To hold idling speed down as well as to keep off any wasteful consumption of fuel by installing a control valve, opening or closing an oxygen enriching air passage, in the point midway in this oxygen enriching air passage, opening this valve only at time of idling, and making oxygen enriching air so as to be fed to an oxygen enriched engine. CONSTITUTION:At time of driving of an oxygen enriched engine 2, each detection signal out of a throttle sensor 36, an intake pressure sensor 38 and a crank angle sensor 44 or the like is inputted into a control part 46, and when a fact that it is at time of idling is judged, both first and second control valves 22, 26 are opened, while a fan 24 is started, and oxygen enriching air is inhaled by intake pipe negative pressure via an oxygen enriching air passage 16. In addition, according to each detection signal out of a water temperature sensor 32 and an oxygen sensor 40 or the like, fuel injection quantity of an injector 10 is controlled to carry out optimum leanness and complete combustion. On the other hand, when the engine 2 is shifted to a running state, these first and second control valves 22, 26 are closed, while the fan 24 is stopped, thus any suction of the oxygen enriching air is checked.

Abstract: PURPOSE: To prevent high temperature steam from flowing into a condenser by calculating a supply water flow rate required for a temperature decreasing unit depending on the operating output to flush tank pressure regulation valve and controlling the steam temperature for the condenser through a damp steam temperature regulation valve. CONSTITUTION: Pressure regulation valve 15 for a flush tank 13 is operated through an PI operating unit 23 based on the difference between the outlet pressure of the flush tank 13 detected by a pressure detector 20 and a set value in a pressure setter 26. Operating output to the valve 15 is inputted to a function generator 27 where a flow rate of supply water being used as cooling water corresponding to the operating output is calculated and a damp steam temperature regulation valve 18 is switched with an opening converted signal thus controlling the temperature of steam flowing into a condenser 6. High temperature steam having temperature not decreased sufficiently by a temperature decreasing unit 16 is prevented from flowing into the condenser 6 due to lag of a temperature detector for steam flowing into the condenser 6 thus protecting the condenser 6.

Filed: 1986-10-17
Abstract: PURPOSE:To obtain a distinct image which is free from a spot and fog, by specifying an area of a projecting part in a minute uneven part on the surface of a toner supply roller. CONSTITUTION:A projecting part area on the surface of a toner supply roller 12 is set to <=30% of a toner carrying area (= width of a toner carrying area S X a diameter D of the roller X pi).
