Title: Adiabatic engine with turbocharger
Inventor: KAWAMURA HIDEO
IPC: F02B37/00
Filed: 1988-11-22
Abstract: PURPOSE:To improve air intake efficiency and suppress production of polluting matters by providing compressors to be turned by No. 1 and No. 2 turbines in downstream and upstream of an oxygen enrichment device, respectively. CONSTITUTION:When a signal for detecting the flow of fuel for an engine 1 is received from a load sensor 12, turbochargers 2 and 3 are started to blow air and an air pressure regulating mechanism 61 are controlled, both of which are related to enrichment action of an oxygen enrichment device 4, according to the detecting signals from a pressure sensor 15 for detecting the sucked air pressure for the engine 1 and an oxygen sensor 16 for detecting the amount of oxygen in the sucked air. By this, the sucked air in an oxygen density according to the load on the engine can be obtained and the production of nitrogen oxide and soot is suppressed since the air intake pressure is controlled at proper low level. Also, a cooler 5 cools a supercharger by means of air supplied from the oxygen enrichment device 4 by a compressor 32. Thus, sucked air temperature for the engine 1 becomes low and air intake efficiency is raised.

Abstract: PURPOSE:To obtain the real sense of acceleration close to a practical vehicle or the like by rotating or moving respective cockpits by a supporting body and controlling the postures of the cockpits by respective three-dimensional mechanisms. CONSTITUTION:When a main spindle 11 is rotated by the driving force of a radial driving part 41, the supporting body 1 rotates together with the main spindle 11 and vertically moved along the main spindle by the driving force of a thrust driving part 42 independently of the rotational motion. Many three- dimensional supporting mechanisms 3 are arranged between two disks 12 on the inside of the outer periphery of the supporting body 1 and respective cockpits 5 are fixed to respective mechanisms 3. The postures of respective cockpits 5 are determined by x axis to z axis driving parts 43 to 45 and the cockpits 5 are rotated and moved by the radial driving part 41 and the thrust driving part 42 to apply three-dimensional displacement, speed and acceleration to an operator. Consequently, the real sense of acceleration close to the operating state of a practical vehicle or the like can be obtained.

Abstract: PURPOSE:To correct an angular error due to the eccentricity of a connecting gear, by method wherein two gears are meshed with the connecting gear provided to a rotary shaft at 180 deg. opposed positions and the signals of the resolvers driven by the respective gears are superposed or averaged. CONSTITUTION:Large and small connecting gears 9, 10 are mounted to a rotary shaft so as to be integrally rotated. A gear 11 of a gear ratio of 1:1 is meshed with a gear 10 and gears 12, 13 of a gear ratio of n:1 are meshed with the gear 9 at 180 deg. opposed positions. The gears 11-13 are respectively constituted so as to driven resolvers and each of the resolvers outputs the analogue signal proportional to the sine and cosine of the angle of as resolver shaft from each orthogonal winding. By this method, the angle data of the gears 9, 10 are calculated. At this time, even when the center P of rotation of each of the gear 9, 10 is eccentric to the center Q of rotation of the rotary shaft, by connecting the resolvers driven by the gear 12, 13 in series to superpose the output signals of said resolvers, the angular shift of the gears 12, 13 is set off and, as a result, the real angle of rotation of the rotary shaft, wherein an error due to eccentricity is removed, can be obtained.
