Title: Secondary air supplier for internal combustion engine
Inventor: IMAMURA YUKIO
IPC: F02M23/00
Filed: 1978-08-28
Abstract: PURPOSE: To attain perfect combustion by displacing residual gas with fresh gas by introducing secondary air from the outside into combustion chamber by pressure difference during engine operation.  
     CONSTITUTION: When negative pressure is produced locally and temporarity in the combustion chamber 22 during the explosion stroke of engine, secondary air put in the distributor 17 is passed through the introduction hole 21 of the noise suppressor 20 and introduced into the air passage 16 formed in the central electrode 10 provided at the firing point through the check valve 15. Through the air passage 16, the air goes into the deep of the combustion chamber 22 because of negative pressure produced immediately after the combustion of mixed gas. On the other hand, because of negative pressure produced during the rear period of exhaust stroke, secondary air is likewise introduced into the combustion chamber 22 and the comparatively low temperature secondary air replaces the residual gas. Also, overheating of the ignition plug A can be prevented by injecting secondary air from the central part by positioning the central electrode 10 below the earth electrode 3.

Abstract: PURPOSE: To omit an induction shunt unit in the control device for the electric motor vehicle and to obtain the control device which is inexpensive and relatively light by utilizing a current smoothing reactor becoming unnecessary upon shortcircuit of a chopper as an induction shunt unit.  
     CONSTITUTION: The induction shunt unit is omitted in the control device for the electric motor vehicle, a switch S 3  is instead provided, and a resistor RF and a current smoothing reactor MSL are connected in series with each other upon closure of the switch S 3 . When the current flow rate of the chopper CH becomes maximum, switches S 2 , S 3  are closed, and a switch S 1  is successively opened. The series unit of the resistor RF and the DC smoothing reactor MSL is connected in parallel with the field winding F of the motor in this state. The motor current does not flow through the switch S 2  to the chopper CH, but operates in the state that the chopper CH is shortcircuited. Accordingly, the smoothing reactor MSL serves also as the function of the induction shunt unit, and can resultantly suppress the deterioration of rectification of the motor current caused by the increase in the motor current.
