Title: Apparatus for controlling injection pressure of fuel in individual injection type engine
Inventor: BETSUSHIYO HIRONORI
IPC: F02D41/04
Filed: 1983-09-26
Abstract: PURPOSE:To lower the specific fuel consumption of an engine, by increasing the difference between the pressure of fuel supplied to an injection valve and the pressure in an injection space or controlling the absolute pressure of fuel supplied to the injection valve to keep it at a relatively high level at the time of operating the engine under a relatively low load, and controlling the absolute pressure of fuel supplied to the injection valve to keep it at a relatively low level at the time of operating the engine under a relatively high load. CONSTITUTION:A control circuit 30 consisting of a micro-computer or the like judges the load regionof an engine from the output signal of a throttle switch 48, the engine speed detected by a crank-angle sensor 40, etc. While the engine load is relatively low, the pressure of fuel supplied to a fuel injection valve 26 is controlled at a relatively high level for completing fuel injection within a short while, so as to promote stratification of air-fuel mixture in a combustion chamber 14 and to extend the lean limit of mixture. Thus, it is enabled to lower the specific fuel consumption and to purity the exhaust emission. In a high-load ragion, on the other hand, the fuel pressure is controlled a a relatively low level for prolonging the fuel injection period, so as to hinder stratification of air-fuel mixture and to promote cooling of intake air by the heat of vaporization so that the air-fuel ratio of mixture in the vicinity of an ignition plug may not become over-rich. By thus raising the charging efficiency of an engine and preventing knocking of the same, it is enabled to increase the output of the engine.

IPC: G01S7/40
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To avoid the repeated addition of the electric field of a ray with the same path history and to calculate electric field strength with high accuracy by recording only one ray with the same path history at a path history table. SOLUTION: A CPU 12 controls the entire device and calculates the path history of a ray and electric field strength, a ROM 14 stores a program executed by the CPU 12, and a RAM 14 stores path history data 17 of ray being calculated. A path history where each ray radiated from the wave source of an electric wave at every constant angle reaches a structure is obtained and the ray passing a specific signal reception area at a signal reception point is selected from rays which are radiated from the wave source and rays which are branched by the structure. When the same path history as the path history of the selected ray has not been stored, the path history of rays is stored at a path history table 23.  Then, electric field strength at the signal reception point of each ray is calculated based on the path history stored at the path history table 23 and the electric field strength of all calculated rays is added.

Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To measure the concentration of nitride with high sensitivity through simple structure by forming a mirror face of metal having high reflectance on the inner wall of a reaction bath. SOLUTION: A reaction cell 2 comprises a reaction bath 23 and a photoelectric detecting section 25 coupled integrally therewith. The reaction bath 23 is provided with a capillary 21a for feeding NO gas and a capillary 21b for feeding O3 gas. The reaction bath 23 is made of aluminum (Al) and the inside thereof is cut into dome shape thus forming a reaction chamber 23b covered by the inner wall 23a. The inner wall 23a is mirror finished. The light to be emitted through chemical reaction of NO and O3 has wavelength band of 590-2500nm.
