Title: Exhaust gas purifying device for engine
Inventor: YAMAUCHI HIROBUMI
IPC: F01N3/02
Filed: 1986-01-14
Abstract: PURPOSE:To improve the reproduction efficiency of a filter, by a method wherein, when liquid, serving to promoting combustion of collected particles, is injected and fed in an exhaust passage on the upper stream side of a particulate filter, bypass is controlled so that a flow rate to the filter is adjusted to an about specified value. CONSTITUTION:During operation of an engine 1, it is decided by a control circuit 22 whether the back pressure of the engine 1 detected by a back pressure sensor 24 is higher than a given back pressure. When higher, a particulate filter 7 is decided to be in a choked state, and an injection amount Q of liquid serving to promote combustion is decided. When an exhaust gas temperature T1 detected by an exhaust gas temperature sensor 23 is lower than a crack resistant allowable exhaust temperature TA of the filter 7, an injector 8 is driven and controlled. When an exhaust gas amount determined from said back pressure is higher than a proper passage amount to the filter 7, the opening of a flow rate control valve 14 is increased, an exhaust bypass passage 13 is opened, and an amount of exhaust gas passing through the filter 7 is maintained at a set valve.

Title: Liquid droplet injector
Inventor: MATSUDA YASUMASA
IPC: B05B1/02
Filed: 1980-01-23
Abstract: PURPOSE: To discern the case of fault in liquid droplets injection characteristics by providing a piezoelectric converter between a liquid trap and a nozzle part in a liquid droplet injector capable of rapidly changing the volume of a pressure chamber supplied with a liquid.  
     CONSTITUTION: When applying a driving pulse under a condition that a liquid is filled up in a pathway from a tank 8 through a trap 6 and conduit pipes 4 and 2 to  a nozzle part 1, a piezoelectric element 14 is deformed and a diaphragm 13 is  warped. And, the volume of an electricity-sound converter 3 is rapidly reduced and  a resultant pressure wae blows off liquid droplets from the nozzle part 1. Then, a  fine hole 15 leading to the conduit pipe 2 is provided in the base 12 and led to the  pressure chamber 21 of a small-size piezoelectric converter 20. The volumetric  change of the chamber 21 is so controlled that the change is smaller than that of the  converter 3 and that no deterioration of liquid droplets injection characteristics  occurs. Thus, the clogging of the nozzle part and the intermixture of gas bubbles in  the conduit pipe can be judged from the waveform of output of the converter 20.

Filed: 1980-01-25
Abstract: PURPOSE:To feed operating power and transmit the information signal simultaneously with a cheap constitution, by causing the slave station to separate and take out power and the information signal by the turn-on and off signal based on the information signal transmitted from the master station. CONSTITUTION:When the digital information signal is applied to terminal (a) of master station 10, this signal is sent to switching circuit 12. Since the power source voltage is applied to terminal (b) of this circuit 12, circuit 12 turns on or off the power source voltage according to the information signal and outputs it. The output of master station 10 is transmitted to slave station 14 through transmission line 13. Slave station 14 smoothes this signal through smoothing circuit 15 and takes out it from terminal (d) as operating power and utilizes it, and obtains the information signal through receiver 16 from terminal (c). By this system, the constitution for superposition and separation between operating power and the information signal is easy, and the cost required for this constitution is cheap.
